Hi all,

My company had just ordered a SQL 2000 Server. I need to make a webpage
that collects data from the Server's database. I guess I need to use PHP
with SQL. My question is what is the difference between SQL and mySQL? I
brought a book that teaches you how to use PHP with MymySQL, I am just
wondering if this book will give me a good enough idea of how to do my job,
since I know a little bit of SQL already. Please advise, thanks.

SQL Server 2000 has a book's online sort of thing, it's a help manual
that is installed
while your installing the SQL Server client (Enterprise Manager) or

invaluable in figuring out functions specific to MSSQL. I highly
recommend just using
that.

Please advise, thanks.

You'd want a book that's specific to MSSQL. Yes, the underlying SQL is the same in each one, but each has a list of functions and features that are specific to it. Having a book on what you're actually using is going to be most useful.

Don't chuck the MySQL book, though. Read it in conjunction with the other and you'll get the best of both worlds...

I'm using the following code to parse the structure of the mail messages, function parse($structure) { global $type; global $encoding;

// create an array to hold message sections $ret = array();

// split structure into parts $parts = $structure->parts;

/* iterate through parts and create an array whose every element represents one part each element is itself an associative array with keys representing the - part number - part type - encoding - disposition - size - filename */ for($x=0; $x<sizeof($parts); $x++) { $ret[$x]["pid"] = ($x+1);

$this = $parts[$x]; // default to text

if ($this->type == "") { $this->type = 0; } $ret[$x]["type"] = $type[$this->type] . "/" . strtolower($this->subtype);

// default to 7bit if ($this->encoding == "") { $this->encoding = 0; }

$ret[$x]["encoding"] = $encoding[$this->encoding];

$ret[$x]["size"] = strtolower($this->bytes);

$ret[$x]["disposition"] = strtolower($this->disposition);

if (strtolower($this->disposition) == "attachment") { $params = $this->dparameters; foreach ($params as $p) { if($p->attribute == "FILENAME") { $ret[$x]["name"] = $p->value; break; } } } }

return $ret; }

and when i use to show the the contents with the following code

if(is_array($sections)) { echo sizeof($sections); for($x=0; $x<sizeof($sections); $x++) { if(($sections[$x]["type"] == "text/plain" || $sections[$x]["type"] == "message/rfc822") && ($sections[$x]["disposition"] != "attachment")) {

$text.= htmlspecialchars(stripslashes(trim(imap_fetchbody($inbox, $id, $sections[$x]["pid"])))); $text.= "<br>"; } } } else { $text.= htmlspecialchars(stripslashes(trim(imap_body($inbox, $id)))); }

$headers = imap_header($inbox, $id); $structure = imap_fetchstructure($inbox, $id);

// if multipart, parse if(sizeof($structure->parts) > 1) { $sections = parse($structure); $attachments = get_attachments($sections); }

if i only have text it works fine, but if i have attachements it only shows the attachements and not the body text.

Any thought on why does this happens?

Hi Chris,

Thanks for the info. I probably need to make myself more clear, as I'm not referring to a database abstraction layer in terms of drivers (e.g., "dbx" in PHP, DBI in Perl).

I think the best example of what I'm talking about is in Tim Kientzle's "Perl and Rapid Database Prototyping" article of December's TPJ: http://www.chipcastle.com/tpj/TPJDecember2002.pdf

The first few paragraphs should give you the basic idea, so let me know if you have any suggestions.

Thanks!

Okay, so if I understand it correctly, you'd try to call a method such as $class->method() where method() doesn't actually exist. You'd want to catch that error, look for a column named 'method' in a table, and either set, return, or do both for the value in the column?

If you call an unknown function, it produces a fatal error, so I don't think that can be trapped by set_error_handler and acted on.

In order to do this, I think you'd have to do something like $class->method("phone","555-1212");

method() will look for a "phone" function and call it if it exists. Otherwise, look for a "phone" column and set/retrieve the value...

Hi all,

I'm about to create a site where visitors will be able to search, view, surf and add items to a shopping cart without logging in to the site, but will need to do that in order to complete the transaction of course. What I wonder, is what to use to collect information about the items the visitor has chosen in order to show them in the cart section... Should I use the no-so-secure old cookies method or should I start a new session every time a client drops in and handle each cart by session name or ID?

Of course I would rather store every visitor's temporary cart in a long MySQL DB and not in their Hard Disks because of those 4 Kb of limit cookies have.

Any suggestions? Thanks in advance,

My advice is to only use cookies to identify a Web client. Any data you want to associate with that Web client (user data, for example) should be stored on the server - database, session store, etc.

Chris

attached mail follows:

Agreed. Sessions are much more secure and convienient to use too. Since it's not reliant on the client to have cookies enabled, that's another benefit. Plus it's MUCH harder for a client to spoof/alter a session variable if you use the $_SESSION['myvar']

This got long, but I structured it so one can stop reading when one gets bored or mired in minutia, and constructively answer based on what was read so far.

So feel free to stop reading after only a couple paragraphs and fire off a response :-)

"+++" marks good stopping-points for this cumulative post/response deal.

I'll take any other random suggestions for how to drasticly improve full-text index/search performance, of course! I examined the PostgreSQL contrib/ directory solutions -- fulltextindex didn't help, and the other option required software/processes we're not able to maintain at this time.

THANKS!!!

---------------------------------------- Under what real-world conditions does a read-only replication of a DB on a RAM disk make sense?

Any quick tips for what NOT to do if I just want to run a quick crude benchmark trial sort of thing using PostgreSQL and PHP?

+++

A Google for "PostgreSQL RAMdisk" turned up only one brief article that seemed geared toward a very small dataset for a hobbyist type site where performance was more about principle than real-world need. (Though it was a VERY nice article with very concise directions and great warnings about "what if")

Perhaps I should have Googled for "MySQL RAMdisk" and hoped the parallels were accurate? I'll give it a shot, but am leery of invalid information from that cross-db assumption. Any comment on the likelihood of non-PostgreSQL info being applicable?

Mailing List archives turned up some interesting discussions, but were generally not conclusive.

+++

Or, to make this easier to answer, if somewhat less useful generally in the archive, do you predict it would significantly boost performance (and why or why not) for:

Intel Pentium III, 1.4 G MHz RAM 1G PostgreSQL 7.3 currently *NEEDS* shared_buffers = 256M, has 512M as safety also set sort_mem = 16384 - not sure it helped/hurt also tried to turn query/perofrmance logging on, but never did find the darn log files to view anything useful (Help!) PHP 4.2.3 The database itself is sucking down 2.6 Gig of hard drive space: du -hc . 3.6M ./base/1 3.6M ./base/16975 4.0k ./base/16976/pgsql_tmp 2.3G ./base/16976 4.0k ./base/3087869/pgsql_tmp 120M ./base/3087869 2.5G ./base 140k ./global 113M ./pg_xlog 720k ./pg_clog 2.6G . 2.6G total

+++

Obviously I cannot currently replicate that whole thing in RAM.

However, a large chunk (1 Gig-ish) of that is a 12 million row table of (int4+int4+int4) == 96 byte records that I was hoping would allow a self-join of word position (concordance) which would be faster than the RegEx across 18000 articles of 0 to 270K in length.

Another large chunk (750 Meg-ish) is a 10 million (int4+int4+smallint) = 80 byte records which are currently being used (and probably must remain) to cross index a dictionary with each article and its frequency in the article.

This 750 Meg table took queries ranging from two minutes to an unknown time down to the 10 second magnitude. I doubt that the RAM disk is going to be enough boon to beat that, right?

I believe that before I added these tables, we were looking at ~200 Meg of data, which makes a little more sense on a RAM disk.

+++

An answer that involves paying for more RAM and making it 40X as fast would be fine, of course.

So if I trade the 1.8 Gig concordance[s] for a RAM disk will the RAM disk give 4X to ??X performance improvement to "make up" for the concordance gains I've already achieved?

+++

Big Picture: It's a custom search engine of texts from over 50 years' worth of a magazine using some specific meta-data to provide searching.

Full-text index searching has been the biggest challenge. No surprise there -- But I had hoped for more definitive solutions "out there" in algorithms and such-like. There were off-the-shelf projects (eg ht://dig), but they didn't "fit in" with some of the meta-data and design constraints.

I've managed to create a concordance of article/word/frequency that has sped up most queries from minutes to ~10 seconds.

Alas, the support for "a NEAR b" is at risk, because the RegEx on 18000 rows of text from 0 to 270K takes too long. (We can drop NEAR if we have to, maybe, but would rather not.)

Only now am I realizing I probably underestimated that 12 million number -- It probably is closer to 20 million or even 40 million. Hard to say for sure until the actual text is indexed or I run a random sampling at least.

I don't even have real data in that table yet -- Just used semi-random numbers to populate it for benchmarking to see what sort of gains I might get. (Answer: 4X is great, but it's not enough.)

And the concordance with full positional information (eg word "foo" appears in article 57 at offset 42) requires an [under-]estimated 12 million row self-join.

A sample table of that magnitude clocks in at 30 seconds just for two words "a NEAR b" without even trying (yet) to correlate those with the actual articles via the dictionary/concordance lookup. And while 30 seconds sure beats two minutes, it's not good enough, particularly when I haven't even factored in the actual article lookup in that crude benchmark.

I think I've just about exhausted the query-munging solutions and am now casting farther afield (EG this RAM disk idea) for solutions.

As a long-time Open Source advocate, I am hoping to publish some of my experience, pending (A) successful resolution and (B) client->client approval. They've been pretty good on that sort of thing so far, but you never know. I'll post here if that works out.

Hi,

I have an application that uses sessions to allow customers to access a restricted area. That is, they are prompted for a user login and password. I then use sessions to track each customer. At the top of each page, I have placed the following PHP code:

session_cache_limiter('Cache-control: private'); session_start();

Everything works fine. However, I have a logout link that when clicked, runs the following PHP code (where userid is the login name):

session_cache_limiter('nocache'); if (isset($HTTP_SESSION_VARS['userid'])) { $HTTP_SESSION_VARS['userid'] = ''; session_unregister($HTTP_SESSION_VARS['userid']); } session_unset(); session_destroy(); Header('Location: ' .

I think the above is all that is needed to end the session. I use the Header() function to take the user back to the login page.

Here is my question: Once I click on the "logout" link and am taken back to the main login page, I can click on the browser BACK button and still get my previous page 'as if I was still logged in'. Please note that clicking on REFRESH tells me that I am not really logged in.

I know that browsers cache pages and there may not be anything I can do, however, I have seen sites that seem to work around this; i.e.., clicking on the back button loads a pages telling the user that they are no longer logged in. This is what I want to emulate. Is there a PHP method to always force a reload the first time a page is called?

Thanks, Don

I believe there something (a meta tag?) called meta-refresh or just refresh.

But I believe you have to set the refresh interval. and if you set the interval to small it might eat your server's resources.

OR I just thought of this, sometimes when you get to a page (usually with forms?) it says that the page is expired and must be refreshed. Maybe you can get that behaviour, so that when someone hits back, they have to refresh.

Don,

The only method that I have discovered to protect the login against the back-button is to validate the session at the top of each and every protected page. Forgive the psuedo code..

<? if active session { // validate privs for this page // session start }else{ // logout } ?>

When the back button is pressed it goes through this process, sees that there is no active session, goes to else and shunts back to the login screen.

Hope that helps, Kevin

I think the method Kevin mentioned is the best.

In other words, on every secure page you have a script that checks is a session registered. IF it is, it lets you go through and execute the rest of the script if not, simply tells you to login that's it. Very simple, if interested I can show example.

Well then pseudo-code a bit not correct; I think it should be like: <? // session start if session registerred { // Do whatever you need } else{ // logout } ?>

But what about such case: Let we have 3 pages: 1) login page(user enters credentials and redirected to page2) 2) secure page (where we validate user, register sess. vars. etc). Than user clicks "logout" and redirected to page3. 3) logout page. We destroy session and logout user.

If at this point user clicks Back button he/she will get message "Warning: page expired" (this is secure page). Because browser still has credentials entered on page 1(login page) pressing refresh button starts new session and secure page is accesible. How this problem can be fixed? Stas

Hi all,

Following Chris's idea on how to handle visitors sessions, I'm trying to setup a cookie with a randomly generated session ID but it throws me the "headers already sent" notice but there's nothing above the setcookie function. Here's part of my code:

<? if (!isset($sessid)) { require_once("PasswordGenerator.php"); $Password = new PasswordGenerator(10, 10); $RandPassword = $Password->getHTMLPassword(); setcookie("sessid", "".print($RandPassword)."", time()+3600); } else if (isset($sessid)) { echo "$sessid"; } [---snip---]

and after all this is then called the header and main files... What is getting outputted to the browser?

Look for white space in the include file ...

I found that the Header already sent problem was caused by the Random Password Generator I'm using, even if I place this function on the bottom of the same file I'm trying to open an just call for the result.

So, to avoid this issue, I need another method of generating a random number or string of some sort like using the actual time which I can place inside the setcookie function directly... anyone knows what can I use?

If the function is the problem, then stop echoing or printing anything in the function, before it, or after it. Make sure there is nothing outside of the <? And ?> tags, especially an extra line break after the closing ?> of the file if it's an include file.

And, you can use uniqid() to create a random string.

Hello,

I try to move an Web application in Php-4.0.3 to php-4.2.3, and some programs don't work well on some pages. I make search in the code, and after tests, I find that the following code doesn't work in php-4.2.3, but works in php-4.0.3pl1 ------------------------------------------------------------------------------------

<html> <body> <form> <? $i = 0; while ($i<=3) { $selected = ""; $selectTab[$i] = "<option value='".$i."' ".$selected."> bla bla </option>\n"; $i++; } printf("<select name='filiere' multiple size='%d' class='textNoir'>\n", ($i-1) ); $j = 0; while ( $j <= $i ) { printf($selectTab[$j]); $j++; } printf("</select>"); ?> </body> </html> ------------------------------------------------------------------------------------

It's because there is an error in the code : this instruction is wrong while ( $j <= $i ), there is an "out of range" in the array selectTab[] when $j=$i=4 the good instruction is while ( $j < $i )

Is there something changed in the gestion of the error "out of range" in an array betwen php-4.0.3pl1 and php-4.2.4 ?

If the PDF forms you "print on top of" are forms, you can use FDF (Forms Data Format) to fill out the form. There are several FDF options. One is to use Adobe's FDF program thingie. Others are listed in the comments on this page (http://www.php.net/manual/en/ref.fdf.php). I used one of the ones listed in the comments with no problems, but it was for a super simple form. (i.e., your mileage may vary)

Another option is to have the suppliers form to be turned into an image and placed in the background (via pdf_place_image() if you're using PDFlib). This works well enough, but could be extremely troublesome for large forms. It also heavily increases the size of the PDF document.

PDFlib is really powerful, but to edit existing PDF documents, you may need to use their PDI (Pdf Import Library). That is an added cost module.

Otherwise, you could create a function (or possibly class) to basically redo the suppliers' form, and then pass over it (at the same time) with the data you need to put on the form.

Good Luck!

When I got this error it was because the server was rejecting the email, saying it wouldn't relay the message. Maybe check your relay setting in your SMTP server?

The email goes through, but it won't process any of the code after it. Is it waiting for a response from the mail server? Can I disable that?

It's already there, the session.gc_maxlifetime setting (default is 1440 seconds).

Actually, this will only work if garbage_collection works on your server. It's all explained on the session page.

If gc doesn't work on your system, then register a timestamp in the session that get's updated with each action. Then just look for timestamps over 30 minutes old and make them log in again.

Hopefully you've gotten the point that this isn't true. If you store your images in the database, it's going to make your main script execute one query to output something like <img src="file.php?id=xxx" ...properties...> for each image. Each one of those <img> tags will be a separate request where file.php would pull the data for _one_ image, send the headers and then send the data.

That makes sense. When Marek explained it I didn't realise that IMG tags can't use the raw data, and needs to make a seperate HTTP request for the Headers.

Now, I understand. Unfortunately the desicion has been made to go with the database.

After much testing, I think I may have it. It appears that MySQL is dropping a trailing space from the value being inserted into the database! For example if the encrypted string is "(.A®¢m¸"¼'À " MySQL stores the value without the trailing space (and it is a space). Why is that? I can duplicate this by entering "test " as the field value too.

# is used to start a comment in MySQL.

Show your actual code around this statement where you make your query. The only reason the data would be cut off is if MySQL is interpreting the # as the beginning of a comment. But, if that was the case, you'd have an invalid query, so it must be a combination of things.

Nevermind. When copying my code to show you I noticed I have HTTP_GET_VARS, instead of $HTTP_GET_VARS, and now everything works.

Time to go home I guess.

Are you using $HTTP_GET_VARS['id']? If it's in a function, then php scopes $HTTP_GET_VARS as a local variable, and thus there's nothing in it. While that's different then most other programming languages, it's how it is in php. If you want to reference the global $HTTP_GET_VARS in a function, then you must 'global' it:

function foo() { global $HTTP_GET_VARS; echo "Id is {$HTTP_GET_VARS['id']}<br>\n"; }

Now the php developers added a new set of arrays to help with that in 4.1.2 (I think), so use $_GET['id'] which always references the builtin global $_GET array. It's better.

i.e. Learn the new way and not the old way ...

checkout the most recent version of the help documents from php.net. it will tell you.

something to do with $_GET, i think...

Wash your mouth out with soap and go learn Javascript...

1. this has nothing to do with PHP

2. this has nothing to do with PHP

3. you could call a frameset html page with <a href="frameset.html" target="_top">

4. you could set individual frames to different sources from one link with javascript -- but you'd have to consult a JS list :P

Hi everyone.

I'm trying to get my PUT method upload to work. I tried the using the script from the manual, but it creates an empty file. <?php /* PUT data comes in on the stdin stream */ $putdata = fopen("php://stdin","r");

/* Open a file for writting */ $fp = fopen("myputfile.ext","w");

/* Read the data 1kb at a time and write to the file */ while ($data = fread($putdata,1024)) fwrite($fp,$data);

/* Close the streams */ fclose($fp); fclose($putdata); ?>

then i tried to sniff on the bugs.php.net (http://bugs.php.net/bug.php?id\20298) site and i found this:

$in = fopen("php://input","rb"); $out = fopen($outfile,"wb"); while(!feof($in)) { fwrite($out, fread($in, $bufsize)); } fclose($in); fclose($out); but that doens't work too...the headers i get are correct: Accept: www/source, text/html, video/mpeg, image/jpeg, image/x-tiff, image/x-rgb, image/x-xbm, image/gif, */*, application/postscript Content-Length: 21504 Content-type: application/x-www-form-urlencodedHost: zenderx

the length of my file is ok.

My question is that... Is this new method of handling uploads already working? How can I handle this kind of upload?

Hi all,

I'm trying to write a grid widget in php. When the user changes the value of a cell the totals must be recalculated at the client side. I can write a javascript when I use simple variables like A1, B1.

This javascript will do the trick:

function njrecalculate() { document.forms[0].mytot.value = Math.round(document.forms[0].A1.value) + Math.round(document.forms[0].B1.value) ;

}

But now I want to create a dynamice grid by using the array variable e.g. mycell[]: <?php echo "<tr><td><input type=text NAME='mycel[]' SIZE=5 MAXLENGTH=5 onChange='njrecalculate()' value=$mycel[0]></td></tr>"; echo "<tr><td><input type=text NAME='mycel[]' SIZE=5 MAXLENGTH=5 onChange='njrecalculate()' value=$mycel[1]></td></tr>"; echo "<tr><td><input type=text NAME='mytotals' SIZE=5 MAXLENGTH=5 onChange='njrecalculate()' value=$mytot></td></tr>"; ?>

Does anybody know how to access these mycell form fields on the client side using javascript.

Food for thought:

As I look through the Zend website, and applaud their efforts to create 'protected' php applications, I can't help but wonder about the impact (or lagality) or their efforts. Doesn't the use of the Zend Encoder (or any other PHP Encoders out there) violate the GPL License or the whole Open Source Concept?

As far as I understand it, the GPL License states that the source code of any product created from an open source solutions, or is derived from the work of an open solutions, must be made availabe to all users.

Since PHP itself is open source, then wouldn't that prohibit a developer from encoding any PHP product?

Please correct me, if I'm wrong. I'm just curious.

GPL isn't the only way to license open source. PHP is not GPL for just that reason. See the LICENSE file in your PHP source directory.

no.

Any modifications made to the PHP source code must be made available to anyone who wants it.

It does not cover programs, applications, websites, created with the programming language. They are covered under their own license (of the authors choosing).

If you created an application, enocoded it, but had made modifications to existing PHP engine code, or even PHP scripting code from other sources, you would have to include unencoded versions of said scripts, and also provide the PHP source (or just your modifications, imported via patch or whatever) to anyone who wants it.

I'm not sure what the deal is with your own custom PHP extensions. I think once again, extensions are separate "programs", and up to the individual to specify the licensing terms.

There are thousands of programs written in C and compiled by GCC. GCC is GPL software. Do you go around saying "You compiled your commercial application with an Open Source tool, therefore you must release all source code to the community"? No. Same principle applies to PHP
