Hey guys, I've got a question regarding a search engine I have to write....
Basically what I have is this..

I have a table with a serialized array in it. I'd like to take that array
and search for keywords... I've got a mySQL database and this is how I'm
doing it...

SELECT a FROM b,c WHERE(b.serializedarray LIKE CONCAT('%', c.keywords,'%'));

Where b is the table containing the serialized data and c is a single column
HEAP table with the list of keywords...

Now... My question is kind of two fold...

A) Is this the best way to do it? By Best I mean considering I am dealing
with a serialized array....

and - thiis is my real question

B) How do I show limited page results? I want to break up the results into
groups of 5 per page and have x pages (count % 5). My problem is that the
origional query gets lost once the page has returned the first set of
results and I have no real way of keeping them... There can be too many to
append to the <A HREF> of the link to the next page and I don't want to use
form POSTS since I have to have buttons for all of them....

Any suggestions?

John

What you really need to understand is, that PHP is a SERVER-side scripting
language. The only way to execute a statement when pressing a button is to
use a CLIENT-side scripting language (JavaScript or VBScript if you're using
Explorer only).

PHP is only run when a page is requested, such as when pressing a link or
submitting a form or the like.

That was a typo. I have IIS 5 on my Win 2K and my friend has IIS 4 on the NT
4 box. Something that I believe is at the heart of the problem is the fact
that in the ISAPI Filters, PHP is associated with php4isapi.dll and the green
up arrow does not come up; there is a red down arrow instead.

I'm wondering how I can do the following (if it is possible at all):

I have 2 values. The first is a constant while the second is not. The second value, in this case, is a unix time stamp and as such will change every time it is set, down to the second.

I need to somehow merge the two values so that the new, merged value would be as (semi) unique as the timestamp value.

I was thinking I could do something like this:

( var1 & var2 )

But that generates an identical value every time.

Is there a way I can do this? And no, I cannot just use the timestamp value. :P And microtime() isn't really an option either. :(

Any help at all would be greatly appreciated! :)

But that would give me a value of a variable variable. And I need a numerical value so

$var1 ="joe"; $var2 = date( "U" );

echo "$var1$var2";

won't do me any good.

I've a very odd predicament...

Hi,

Is the first value a numerical value (real/integer?) or a string value?

If it is numerical, then one of the things you could do for using a numerical value of (say) less than 100 could be:

$finalVar = ($var2 * 10) + $var2;

This is one of the simplest things you could do and meant only as a rough example. A faster way would be to right-shift by 4 (if that can be done in PHP) instead of multiplying by 10. This well essentially multiply the number by 16.

I am relatively new to PHP, so the syntax I have used may not be correct. Sorry about that.

Does this come anywhere close to what you would like to do?

It can be done, but it is not fast enough to do in real time.

The way I create thumbnails is ImageMagick. I keep my thumbnails in a hidden directory (.s) and create them like this:

mkdir( "imagedir/.s" 0700 ); system( 'cp imagedir/*.jpg imagedir/.s' ); system( '/usr/local/bin/mogrify -geometry 150X150 imagedir/.s/*' );

The last command will take an image of any size and aspect ratio, maintain the aspect ratio and resize it so the largest dimension is 150 pixels. There are MANY other commands available.

Your thunbmails have the same names as the full size files, but are stored in imagedir/.s/.

I have a user database where a year has to be put in.

Is there a way to do this beyond coding for each year:

SELECT * FROM students WHERE year = '1983' ?

You could try something like this:

SELECT year, count(studentID) FROM students GROUP BY year

...where studentID is the primary key column/field in your students table.

I have a Cobalt Raq 2 with with 2.0.34 kernel installed. When I compile PHP and then try to execute it, it will dump core with the following message:

Floating point exception (core dumped)

I'm untaring the files, cd'ing to the directory and running './configure' and then 'make'. The compile appears to work fine, yet when I run the php executable in the php directory, I get the above error.

The only change I have made to the system is to install all the Cobalt security patches and then install flex 2.5.4 and bison 1.28. Otherwise it's a stock Raq2.

One other thing: configure sees my system as mipsel-unknown-linux-gnu.

Anyone have any suggestions?

It is possible (I've done it) to find out all the variables that make up a form on a particular site, generate a similar form on your site with that form's action being the CGI/PHP script that the particular site uses to process the form once submitted, modify the values for the form variables to be anything you want and submit the form that resides on your site. This will basically submit totally fabricated data to the foriegn site and possibly screw them up somehow and/or in some way.

Is there any way to defend against this? Is there any way to ensure that when a form is submitted that the submission request originated from your site/domain and not somewhere else?

Any help would be greatlyl appreciated.

Knowing that $HTTP_REFERER cannot be relied on as containing valid data (as some browsers don't support it)?

No. There is no way to tell a clever programmer from a live human on the other end of an Internet connection. You may be able to make it harder, say making sure your form page is hit before the results are returned, but that is easy to defeat.

I can think of one way that you can take in an attempy to prevent this. It is not totally fool proof but it will make it more difficult to send spoof data:

1) Check your HTTP refereer when the form is submitted. If the referer is not from your host then don't process the form. Of course this can be faked quite easily if this person knows what (s)he doing.

I would think you should be able to write a random string to a file when the form page is accessed, and carry a variable with the action then have the recipient compare. Presents other challenges but should give you that comforting feeling he was looking for.

Well, this was part of what I was going to do. I was going to check to see if the request method was post and if the referer was from our host (not just the form/page). If all that was true, then process the form. If not, don't. However, I know that the $HTTP_REFERER variable is not at all reliable. On that note, what browsers/versions would not send this information for Apache/PHP to set? I know it is because of the browser that the client is using that this variable is unreliable. But what those browsers/versions are, I don't know and am hoping someone can answer.

Don't bother with checking the HTTP_REFERER - it can be easily forged.

There is a very simple solution to this problem -- validate the data from the form!

I.e. if you're expecting $foo to be an integer from 2 to 5, look at intval($foo) and see if it's >=2 and <=5.

You should be doing this anyway, since who knows what the user could type in your input box. Nevermind if somebody makes a copy of your form. Never never never trust the client.

Would it not be possible to have both the form page and the script page that handles the form be generated o the fly with random filenames?

The form page would point to the random generated script page, and the script page could delete itself after it is proccessed. You would also want a cron to delete any files in case they never bothered to submit the form.

Can anyone see a problem with this?

I'm already doing this. However, if I have a hidden variable containing a value of the current user I'm working with, that value can be changed to something else and it would pass the test. However, I need to find a way to determine if something like that has happened. That's where my description of what I was thinking of doing came from.

That is not going to solve the problem, because a cracker can just copy and paste the random filename of the script page into their form page.

Bogus form data is a problem for everyone working with html forms. You're trying to find an esoteric solution to the problem, while overlooking the obvious: just check if the data is valid.

Does the user have a password? You need to check if the password matches as well.

Yes, but that's not going to do me any good because it is valid for one user to act on behalf of another (as a broker, if you will). So the currently logged in user might not be the one who's ID is in the hidden field...

No wait, I see what you mean. You're right, sometimes the obvious is missed, but it sounded cool.

It has to exist long enough for your form to post to it, which is long enough for their form to post to it as well.

So how do you verify that the logged in user is allowed to act on behalf of the other ID? You just have to keep reverifying that the client is allowed to do what they're doing.

It's a chore I know - security usually is :(

ALl that means is that I have to load your form, identify your magic number, and send it when I return the form data. That makes it a little harder, but only a little. The magic number will be in a hidden field, but hidden fields are not all that 'hidden' when you View Source.

I'm working on a chat of sorts, and in the main frame that shows the actual messages, there is an infinite loop (while(1)) ... now, for whatever reason, when the browser is closed, the loop/thread/whatever just won't die. There are sessions involved, and the loop basically just checks a MySQL DB for new posts, and updates a timestamp in a user database. Any idea of why the loop/thread/whatever won't die?

Thanks,

PHP is server-side. It doesn't know anything about a (client-side) browser window being closed.

If you don't want the admin or web server user to see your code, you may want to consider Zend's Encode product (http://www.zend.com/zend/products.php#encoder) which encodes your PHP code for you. BUT, this can be rather expensive (depending on your use) and you probably still need your Administrator to install it for you, so I'm not sure if this does you any good or not.

Hey!

I'm sending this e-mail only to you, since it's way off-topic from being in the php-general mailing list.

I have downloaded Netscape 6, it seems that Logical Hebrew isn't support yet - only Visual. So if Netscape 4.x (except for the 4.61 version developed by IBM), Netscape 6, and Opera does not support Logical Hebrew why should I use it??

What do other Hebrew web sites do regarding this matter? Do they make two versions of the same web site, one for Netscape and one for IE?

For conclusion -

I'm working on a Hebrew website. I want this website to look ok in both browsers (IE and Netscape), and I want this to be done the easiest way possible.

What should I do? Use Logical Hebrew and ignore the fact that Netscape does not support it? or maybe I should use Visual Hebrew (reverse all the Hebrew words using some utility such as - "EasyHEB"), or maybe I should use Logical Hebrew in the HTML itself and turn it to Visual using a PHP script? (doing that would be rather complicated.. hebrev() and hebrevc() aren't enough..)

Thank you in advance -

Postgres also has a nasty show-stopping bug they don't seem to want to fix. Try making a stored procedure with many parameters, and send a single null to it. I dare you. I so love having all of my other parameters, and the return value of the function turned into null because postgres can't tell where a null occoured.

I also love the fact that you can't drop foreign keys, modify columns, drop columns without rebuilding the entire table, etc. We use it here, but it makes me want to pull my hair out. If someone would just combine postgres and mysql, we'd have the best database in the universe. Fast and stable, with all of the RDBMS anyone could want.

But as it stands, postgres is still a bit player with an incomplete feature set. But I don't want to start a holy war here, so I'll drop it.

This only occours if you don't know how to optimize Oracle. Oracle is *very* picky about *everything*. You need index tablespaces on separate disks from the data tablespaces, and yet another one for system tablespaces. You should also have one for archive logs, redo logs, and of course your temporary tables. Setting it to threading mode is also nice for connection pooling and to stop killing your machine under heavy load.

That, and the machines you've quoted are in no way powerful enough for production Oracle databases, period. You should also run oracle on some kind of Solaris/Sun combo. Raw mount points direct to the actual disks is ideal, but loopback filesystems work just as well. Remember to cluster your raid into 4 - 6 arrays of 3+ disks, too. There is no such thing as a default Oracle install, because installing oracle on a single user machine with one disk and only a little ram (yes, anything under 512 is very little for Oracle) will make Oracle look like a piece of crap.

The point about Oracle is that it *lets* you do all of those optimizations, and if you're good at it, it will outperform almost any other database you throw at it. Trust me on this one.

I'm sorry, I can't trust you very much on this. Having worked as a high-end Oracle tuner on a 1 terabyte database for 3 years and having recently been involved in a new DB2 app, I find DB2 to be as good if not better than Oracle in very many important ways.

Not even including a cost that's about 1/4 of a highly discounted Oracle cost model for an identical HA envioronment.

Hi. I use this function with the strings I'll be showing in tables to cut strings too long without spaces. To make it clear:

The table will be 50px width if $str isn't too long. Let's say: $str="aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" The table goes to hell. So: function cut_text($res,$long=15,$max=20){ if ($max<=$long){$max=$long+2;} $ant=""; while ($res!=$ant){ $ant=$res; $res=addslashes($res); $res= preg_replace ("/(\w){".$max.",}/im","'.substr (\\0,0,$long).' '.substr (\\0,$long,strlen('\\0')-$long).'",$res); $res=" return '$res';"; $res=eval($res); } return $res; }

For example: $str="Hello Howwwwwwwwwwwww arrrrreeeeeee yyyooooooouuuuuu"; echo cut_text($str,7,10); Results in: Hello Howwwww wwwwwwww arrrrre eeeeee yyyoooo ooouuuuuu

The idea is: any word longer than 20 chars will split into a chunk of 15 and a chunk of 5. If you have a 45 chars string, it will leave you with 20, 20 and 5. It works fine with simple text, but with characters like ", / , $, etc. sometimes I have problems. I tried with quotemeta instead of addslashes but the problem persists. Anyone have an idea?. If you want to test the code, just try with Testing \" quotes

Thanks in advance

Hi. I use this function with the strings I'll be showing in tables to cut strings too long without spaces. To make it clear:

For example: $str="Hello Howwwwwwwwwwwww arrrrreeeeeee yyyooooooouuuuuu"; echo cut_text($str,7,10); Results in: Hello Howwwww wwwwwwww arrrrre eeeeee yyyoooo ooouuuuuu

I dont know how to do this, but Ive tried several things with no success. I need to validate several form fields and here is the script I'm working with...

<?php if($HTTP_SERVER_VARS["REQUEST_METHOD"] == "POST") { (eregi("^[a-z0-9\._-]++[a-z0-9\._-]+\.+[a-z]{2,3}$", $Email))? header("Location: http://www.site.com/thanks.php"): header("Location: http://www.site.com/error.php"); } ;?>

I need to check at least two more fields, possibly 3 but I keep getting errors when trying to loop through a bunch of if statements. The above works fine but I need to check eregi() against more strings from fields which then redirects as shown above. Anyone?

I am looking into sessions at the moment and havn´t got it all working properly to continue my journey.

I´m having problem with the session_destroy(), and after some searching in the archive, I found out that other people have had this problem aswell, but I didn´t find a fix...

Here is the error message I get: Warning: Session object destruction failed in E:\Inetpub\wwwroot\testscript\sessions\test.php on line 5

Here is my code: <?php session_start(); session_register("value"); session_unregister("value"); session_destroy(); ?>

Is this error caused by php.ini, my webserver or other?

My configuration: IIS 5 for Win2k PHP 4.0.3 PL 1

Why would you want to create and destroy the session data during a single request? That simply doesn't make sense - session persistence is designed to keep registered session data available across _a_series_ requests.

I believe PHP chokes at session_destroy() since the session save file has not yet been created, and thus deleting the session data returns an error code.

Try this - it should work:

<?php if ($isset($value)) { echo "thanks"; session_destroy(); } else { $value = 12; echo "<form><input type=hidden name=value value=$value>"; echo "input type=submit></form>"; session_start(); session_register($value); } ?>

This I know, but it was just to show what I wanted to do.

I first got the problem when I tried this tutorial at Zend: http://www.zend.com/zend/tut/session.php

I found it funny that a tutorial about sessions had such a "bug", since it was supposed to cover this feature.

Complete source can be downloaded here: http://www.phpwizard.net/resources/tutorials/session_intro.html

I had to change some in your code (lines marked with >>)...

<?php // removed $ from $isset >> if (isset($value)) { echo "thanks"; session_destroy(); } else { // These were below the echo before... >> session_start(); >> session_register($value); $value = 12; echo "<form><input type=hidden name=value value=$value>"; echo "input type=submit></form>"; } ?>

Error message: Warning: Trying to destroy uninitialized session in E:\Inetpub\wwwroot\testscript\sessions\test.php on line 4

Just a thought... Could it have anything with the session.save_path? session.save_path =e:\Temp\sessions

Okay - Im writing an object to wrap a database. The key problem is this: - it declares a connection var as an object property - the open() function opens the connection to the database and stores the handle in $this->connection - the executeQuery() method complains about not having a valid handle, because by then, somehow, $this->connection==null!!!

Any ideas?-i swear its just something stupid ive missed ...

HELP!

open() is simply supposed to open the connection to the database and store it in $this->connection. As you can see - it gets the connection info from either the objects properties or from parameters passed to it. Can you see what Ive done wrong...if anything?!?!

What happens if you do:

<?php $db = new PostgreSQLDataSource("host", "port", "user", "pass", "db"); $db->open();

echo $db->connection; ?>

Well, you already have code to PostgreSQLDataSource ... the other object just encapsulates it ...

ok heres some more code:

class AbstractDataSourceManager { var $dataSourceName; var $dataSource; var $error_handler;

...

function open() { <make $dataSource object with connection params>

if (is_Object($dataSource)) return $dataSource->open(); else return false; }

function executeQuery( $queryString ) { return $this->dataSource->executeQuery($queryString); } }

-------------------- Test Code:

if ($HTTP_GET_VARS["testno"]==7) { $manualNameTest = new AbstractDataSourceManager("PostgreSQLDataSource","","","wwwuser","","rp2"); $result = $manualNameTest->executeQuery("select * from requirements;");

$db = new PostgreSQLDataSource('','','wwwuser','','template1'); $db->open(); echo $db->connection."<BR>"; echo $db->executeQuery("select * from issues;"); }

---------------------- Test Output:

The connection in open() is :Resource id #1 The connection in executeQuery() is :''

Warning: Supplied argument is not a valid PostgreSQL link resource in /var/wwwroot/php/PostgreSQLDataSource.php on line 67 <this is the pg_pConnect line...> The connection in open() is :Resource id #2 Resource id #2 The connection in executeQuery() is :'Resource id #2' Object ----------------

So in other words, the one using the encapsulator doesnt work - it seems to lose $this->connection in PostgreSQLDataSource when its contained in AbstractDataSourceManager !

... theres something screwball here - i mean - an object should be able to access its own properties in any scope at any time shouldnt it ?

This is totally screwing me here ...

Ahh dont worry - figured it out!!!

If anyone cares:

In the encapsulating class i had two copies of the same variable and i was calling the local copy of open() not the object version ...

Hi,

I'm trying to truncate a txt-file which I in my script use "http://mydomain/path/to/my/file.txt" as a reference but I get this error message:

Warning: can't truncate sockets! in domains/mydomain/www/path/to/my/phpfile.php on line 47

Does it mean I'll have to use "real" path e.g. c:\\domains\\mydomain... (etc.) or is it something else I should focus at? I'm working on a remote server (Linux/Apache) but this works 100% on my local server (Win2k/IIS5).

well, because you are using "http://" PHP will have opened a tcp/ip socket :)

try using both fread() AND fclose()

from the manual: http://www.php.net/manual/en/function.fread.php

// get contents of a file into a string $filename = "/usr/local/something.txt"; $fd = fopen ($filename, "r"); $contents = fread ($fd, filesize ($filename)); fclose ($fd);

then truncate $contents

not sure, but should work...

I'm trying to use the example of mail() from php.net:

<? mail("equick-laughlin", "testing php mail function", "Line 1\nLine 2\nLine 3"); ?>

and I've configured my php.ini with the following:

[mail function] sendmail_path = /usr/sbin/sendmail -t -i ;for unix only, may supply arguments as well (default is 'sendma il -t -i')

Yes it still doesn't send for me. I've checked that sendmail is running, and I did a which sendmail to confirm it's location.

When I run the php script and do a tail -f /var/log/messages, it doesn't show up.

How can I further troubleshoot this?

Greetings, fellow PHP hackers!

The current project I'm working on is porting software written in Tango to PHP4. Because these programs heavily rely on information held in (off-site) databases, the tango programs were written to have a set of array variables declared from SQL queries, which then any user hitting the site would have access to.

Ie...

User 1 hits the webapge.. the server realizes this is the first user and populates the arrays with data from the source database. The page is able to use these arrays.

User 2 hits the webpage.. the server already has the arrays packed with data, and user 2 is able to hit the pages quickly, due to no queries being made. All users are this way.

Some events would require that these arrays be re-hashed such as when a user updates, inserts or changes the value of an item in the database. These changes.

When this update happens, the changes would be made to the server-wide variables, so ANY user on the machine (independant of sessions) would have the fresh data when it next pulls from the arrays.

....

Ideally, this would be like settings HTTP_SERVER_VARS[school_array] to contain the data, where every page would have $school_array there without any additional work, and a refresh being a small function that creates the arrays needed and sticks them into HTTP_SERVER_VARS[array_name]. (Along the lines of PHP_SELF, but not dynamic in that sense.)

Some of this could be handled with sessions, but my concern is that carrying ALL of this data with each user is a waste of resources, and will require more database calls than needed.

If anyone has ANY ideas, PLEASE share them! :)

Regards,

Michael

Hi Michael,

I've never used it myself, but this may be of some use:

http://www.php.net/manual/en/ref.shmop.php

If I understand it correctly, this lets you write a string into an area of memory which can be accessed from any process - i.e. another httpd process.

If you wanted to save an array you would need to serialize() it first.

Cheers

Hello again :-)

First, thanks for your help !

but it doesn't work, i think i don't make the right things !!! because i don't understand very well what i must do :-)

For best explain, i must use PHP because my server disallow .htaccess files, this is the .htaccess files i must transform in PHP files :

<limit GET> HTTP_REFERER require valid-user Satisfy any order deny,allow deny from all allow from 198.143.15.0/24 allow from 202.139.84.0/25 allow from 210.176.142.64/26 </Limit>

The script allow all users who are connect with an IP Address between 198.143.15.0 and 198.143.15.255 or between 202.139.84.0 and 202.139.84.255 or between 210.176.142.0 and 210.176.142.255

All other users with other IP Address are disallow and redirect to http://www.yahoo.com/ for example or 403 Page.

Information about network : 198.143.15.0/24 (255.255.255.0) 202.139.84.0/25 (255.255.255.128) 210.176.142.64/26 (255.255.255.192) numbers "0/24" or 64/26 is the range from 0 to 255 for the IP Address

Could you help me once again, please.

Thank you ! Have a nice day.

Anthony.

I know I've been posing some funky wierd questions all day, but today has just been one of those days... I'm just trying to get a sense of other possibilities. And to find out what's plausable and what's not.

Ok, here's my situation. I've a script that generates a variable number of HREFs/anchors. Each of those HREFs can go to variable pages and also have a variable number of GET variables. So, for the sake of this example, lets say my script generates the following HTML:

-----------

<a href="/hispage.php?var1=xxx&var2=yyy">Here<a/><br> <a href="/otherpage.php">There<a/><br> <a href="/thatpage.php?joe=bob">This Place<a/><br> <a href="/lapage.php?this=that&his=hers&here=there">That Place<a/><br>

-----------

As you know, those variables are being passed to the linked page via GET variables. Now, here comes the oddball question:

How can I (is it even possible) pass those variables to each page w/o using GETs and w/o using Cookies. Ultimately, the plan they are pushing is to make our site(s) free of all GET variables (including the SESSID; yes, you read that right) and of cookies. Also those GET variables above should be turned into session variables if and when possible, but only if the user clicks on the actual link.

This is basically the environment that has been presented to me. Is such an environment possible? If so, how? What is necessary to make it work this way? If it is not, to what extent is it possible?

Thanks for reading this far. Thanks, also, for fielding this question and offering any help and any insight you can on my dilema.

Hi Chris,

For my own edification, how are you creating the links dynamically - I need to do something similar ..?

As far as removing GET variables, you could just flag variables in a database, that would eliminate the majority of the inter-page stuff.

You would still need to leave one session on the client, though...

So basically each one of my links would have to be it's own form with each one of the variable number of GET vars as hidden elements along with the SESSID? And no, I couldn't make it one big form because:

a) the GET variables can have the same name but different values

b) these links could be right next to or miles apart from each other, depending on positioning.

And if they each have to be their own form, that would do some funky things with regards to display... Lining them up would be a bitch. :p

Also, how would I set the (previously GET) vars up as session variables? I'd have to post to yet another script which would set the session variables and in turn SUBMIT (with just the SESSID this time) to the actual page (remember, I can no longer use any GET variables so the header() function would be out) that is the final destination...

Like I said, it's been one of those days and the above is the only solution I can come up with to my environment scenario/dilema.

I'm hoping there is a better way.

Just include the SID as a hidden input. It'll be POSTED to the next page right along with your other variables. There's even a way to configure your php.ini file so that PHP includes the hidden SID for you. I forget which setting it is--maybe "trans-id" or something like that...? Poke around in the the "configuration" chapter of the manual; it's in there.

Thanks, Smarty looks like it will do the trick and has some really neat features, like being able to nest dynamic blocks, I think this was my problem with FastTemplate.

i built a script to generate passwords:

function passwort($laenge) { $allowed = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890:-+="; $allowed_length = strlen($allowed);

$i=0; $pw = "";

while ($i<$laenge) { $pos = rand(0,$allowed_length); $pw.= substr($allowed,$pos,1); $i++; } return $pw; }

My questions is, if this is a good or bad way?

It's a whole lot better than using real words. As long as you encrypt the passwords using a good one-way hash when you store them on the server, you should be fine.

That's possible.

You might like to try manually downloading the file using a utility like wget or curl. This will show you if PHP is outputting any errors (which would thus result in a broken image).

Create a new file called test.php and in it put:

<?php phpinfo(); ?>

FTP it to your web server and then look at it in your browser. It should tell you a whole lot of stuff about how PHP has been configured on your server.

create a file called phpinfo.php and add to that file <? php_info(); ?> then load up that page in your browser. In regards to FAQ's visit www.php.net should also look at phpbuilder.com and there are many more. On php.net in the links section they have even more links to FAQ's

Hello,

Are there any good examples of producing embedded javascript code in a php file?

I am having a weird problem with some javascript that simply will not execute, even though I've properly used slashes to prefix quote marks etc.

I don't get javascript errors, it simply doesn't run like it should.

Me thinks this is simple, but I can't seem to figure it out. Thanks

I wish to trigger a small php script from a button on the displayed page without changing the page. Specifically, I wish to destroy the session.

I can't create or manipulate jpegs, but pngs work fine. I am using a hosting service. They installed GD 1.8.4 with jpeg support a few days ago, but I'm thinking they did it wrong. I'm using code I know works because it's straight out of the PHP Cookbook. What do I need to tell them to correct the problem?

phpinfo() tells me this: './configure' '--with-gd=/opt/local/src/gd-1.8.4' '--with-config-file-path=/usr/local/lib' '--with-ttf=/opt/local/src/freetype-1.3.1' '--with-jpeg-dir=/opt/local/src/jpeg-6b' '--libdir=/usr/local/lib/'

This is the code I've tried: <?php header("Content-type: image/jpeg"); if (($im = ImageCreateFromJpeg("test.jpeg")) == "") { echo "error opening file"; exit; } $red = ImageColorAllocate($im, 255, 0, 0); ImageString($im, 3, 20, 10, "Hi", $red); ImageJpeg($im); ?>

They probably didn't build jpeg support into their gd library.

I'm experiencing strange behavior with my user authentication scheme in my PHP app, with users using IE 5.5 (PC and Mac).

I am using browser authentication (WWW-Authenticate and 401 headers), "no cache" headers, and PHP 4 sessions.

I am finding that even when the user totally quits IE, if he then restarts IE, one or both (haven't isolated for sure yet) of the following happen:

- The browser still knows the user and password, and so will send it to the server upon an authentication request under the same realm, without prompting the user. (The user does NOT have "save this password" checked on the user/password prompt when it first comes up.) - The session is still active. A call to session_start() returns the pre-existing session, instead of getting a new one.

If the user restarts his machine, IE no longer remembers his user and password, and so a prompt is displayed upon authentication headers being sent. And I presume (not 100% certain) that a new session gets created.

Both of these are behaving like IE is still running. Is this a known issue with IE 5.5? Does it just stay running? These symptoms make it sound like this, and less like a logic problem in my PHP app. (I have verified that the username and password are sent when the user gets an authentication prompt, without the user typing anything. I'm assuming there's no possible way that a PHP session can retain this information; I am reading $PHP_AUTH_USER and $PHP_AUTH_PW...there's no way these can be set unless the browser were already running and the user had previously entered them into their prompts, right?)

Has anyone else run into this? My application works perfectly under Netscape 4, IE 4, and Opera 5.

Thanks, Ken
