Yes -- and it's called PHP!

The following is taken from the online manual page at http://www.php.net/manual/en/ref.session.php:

  The session module supports both methods. Cookies are optimal, but
  since they are not reliable (clients are not bound to accept them),
  we cannot rely on them. The second method embeds the session id
  directly into URLs.

  PHP is capable of doing this transparently when compiled with
  --enable-trans-sid. If you enable this option, relative URIs will be
  changed to contain the session id automatically. Alternatively, you
  can use the constant SID which is defined, if the client did not
  send the appropriate cookie. SID is either of the form
  session_name=session_id or is an empty string.

Cheers!

Mike

Hmm. I thought this should work as well. This morning, though, I had to fix
a bug where a combo box was displaying something like

"January"
"March"
"March"
"April"
"May"
"May"

...

The code was

<select name="lm">
  <?php
    for ($i=1; $i<=12; $i++) {
      echo "<option value=\"". $i. "\"";
      echo ($i == $lm) ? " selected" : "";
      echo ">". date ("F", mktime (3, 0, 0, $i)). "</option>";
    }
  ?>
</select>

When I changed the mktime parameters to (3, 0, 0, $i, 1, 2002) it all worked
fine.

I think it's because it's the 31st today, and any months that don't have 31
days were getting screwed up (wouldn't mind hearing any other ideas though).
It seems like it's always a good idea to pass at least the day parameter to
mktime(), unless you enjoy unpredictable results ;-)

It's not something you have absolute control over - some proxies are
configured to ignore your caching instructions anyway.

All,

I have a text field that a user can enter text into, I then explode it
into an array, and ultimatley build a regular expression such as:

/(advance|racingx)|(advance|racingx)/i

for use in:

preg_match ($reg_expr, $file);

however the expression above doesnot yeild the required result, it will
match a string with any word, whereas i want to match strings with BOTH
words present.

example of the contents of $file that might pass is:

advance_racingx_14_4_29.pdf

another might be, which would not pass is:

advance_fork10_3_4_11.pdf

Thanks in advance for your help...

If you need it to be in that specific order, use the following:

if(preg_match("/advance.*racingx/",$string)) {
//do stuff
}

If the order doesn't matter, do this:

if(preg_match("/advance/",$string) && preg_match("/racingx/",$string))
{
//do stuff
}

There may be some more efficient/elegant ways to do this, but the
above should yield the results you are looking for.

My company contracts for the National Institutes of Health and the National
Cancer Institute. A group of us are developing a website for State Cancer
Profiles - ie, you want to see the trend of lung cancer in the Total US v.
Kentucky kinds of things. All of the graphs that I'm working on are being
developed dynamically using PHP.

Unfortunately, the site isn't public yet, so I can't send you a link. We
should be live sometime this summer. At that point in time it will be a
link off of www.cancer.gov.

Good luck! If you want any more information, I'll see what I can get you
and your client. I know examples of the site have been shown to people on
Capitol Hill, so it is possible I could send you the password for the test
site. I'm not in a position to make those kinds of decisions :-)

Here are some random government PHP pages pulled off a quick Google search:

No. Do one query with count(*), one with limit. If you're smart, you'll save the total amount in a session somewhere so you only have to do that query once, anyway.

No. PHP is a server side application. The only way to run a function or php program is to send a request to the server. When you do that the server sends back a response and your broswer refreshes the page.

javascript onclick or whatever can call a PHP program on your server.

If Michael Sweeney is right that you can run PHP in a JS method that would work. I just do all of my "instant gratification" stuff in JS. I guess it depends on what is in the PHP function that he wants to run - it's possible that he could do it in JS.

you are missing header('Location: blah.html') :)

Hi, Jason.

I'm developing some really cool line/point and bar graphs. While the Image stuff is definitely quite different, I think you'd really like it once you get into it. Our graphs are generated dynamically from data in a database. I can't show you the graphs because they aren't ready for the public yet, but on the line/point graph we actually have the points as different shapes and stuff - circles, triangles, squares... Once we get the new version of PHP we'll be using styled lines (dot dash dash kinds of things) with a width, so they will be easily copied in to PowerPoint presentations.

It's a lot of work to get it started, because you have to figure out where you're going to want everything to go, but I recommend trying it. Start by drawing some rectangles and filled rectangles and stuff like that.

Oh, and when you use ImageTTFText, I recommend that for smaller fonts you use -$fontColor instead of just $fontColor - it comes out clearer. For bigger fonts sometimes the blurry one is better because it's less pixilated.

Good luck! If you need anything else, let me know!

-Natalie

Just want to run this by you all to check the feasibility of it.

I run a site that deals with cars, people can upload pics of their vehicle and tell everyone else its year, color, 'generation', and where they're located.

What I'd like to do is make some graphs on the front page that look like gauges you'd see in a car, i.e. speedometer, tachometer, oil, etc. but these would actually be graphs showing, for instance, how many of the cars on the site are red, or whatever the most popular color is. So if a majority of the cars were red, and red cars made up 57% of the total cars on the site, I'd want a graphic of a speedometer with a needle that would be in a position that represented 57%.

How difficult is this? I looked at some of the imagecreate() functions in the manual, but they look like a language all their own and I'd like to know if there's any easier way to do this that I'm overlooking. I'm thinking doing some kind of image overlay is the way to go, but not sure. Any ideas or pointers would be great, links to sample scripts would be excellent. Thanks!

Are you talking about five fields in the table containing up to five URI's for each project? That's not cool. You should "normalize" that structure. Put the project info in one table and then the URI's in anohter. This allows you to efficiently store as few or as many URI's as your heart desires.

Can anyone here shed some light on this issue?

I have a class which is responsible for it's own database access and (some of it) is initalised as below:

<? class myClass { var $conn; var $sth; // etc...

function myClass ($db) { $host = "localhost"; $user = "user_name"; $password = "password"; $this->conn = mysql_connect ($host, $user, $pwd) or die ("Unable to connect to database"); $sel = mysql_select_db ($db, $this->conn); if (!$sel) die ("Unable to select database"); return true; }

// rest of the class } ?>

Now, say for example the class is used as per the script below:

<? require ("myClass.class"); $c1 = new myClass ("first_database"); $c2 = new myClass ("second_database");

// error here $c1->doSomething(); ?>

When I try to work with the first instance of my class, I get an error which I finally tracked down to it trying to run it's SQL queries against the database defined in $c2. Now, I was under the impression that class variables were private to each instance, however, this seems to be acting like a static var.

Help?!?

You need to specify $this->conn in each mysql_* function you call otherwise it will be called against the last connection made.

I have the following issue:

I am making a "gas guage" based on a percentage. ie. - a 180 degree arc is created - the range will be 0 to n (undetermined ammount) - there will be x number of entries - the needle will pount to a a percentage for (int)floor((x / n) * 100)

The issue is, I have the starting pt for the needle (imagefilledarc needs the center of the 'circle' as the starting pt, which is where the needle will start too), but how would I get the x|y coordinates for the end of the needle based on a perentage of a half-circle (180 degree arc)? Appreciate any clues or ideas.

--- Michael Geier

attached mail follows:

I believe you will need to use sin and cos to do this...

I experimented with drawing circles in javascript (sorry, it's not PHP but you can see the concept) and ended up with this:

for (j = 0; j <= 360; j += (360 / 10)) { // x1 & y1 are offset values var s = x1 + radius * Math.cos (j); var t = y1 + radius * Math.sin (j); setLayer (layer_count, s, t); layer_count++; }

You would be able to work out the angle by making it a percentage of 180 degrees - although for horizontal gauges, you would need to offset it by -90.

Hope this helps...

Good day,

Wow, a high school math question.

You should use asin() and acos() of the angle to get the y and x differentials, respectively. Multiply the result by the size of the needle.

This assumes that your guage is oriented horizontally, and the needle sweeps from right to left, pointing upwards. Adjust the sign or switch the functions around if your gauge is different.

Note that the functions operate in radians (2*pi radians == 360 degrees).

Did I mention I hate math [grin]... ok...so here we go so far...

I am passing a variable diameter of the arc ($d), the total number of widgets possible ($n), and the number of current widgets ($x)

so let's say $d = 100 $n = 100 $x = 50

$perc = $x / $n (0.50 or 50 %)

degree conversion = # * (180/M_PI)

asin($perc) converted to degrees = 30 acos($perc) converted to degrees = 60

my arc runs from 180 deg. to 360/0 degree, or left to right, pointing upwards (upside down U). i guess I am not getting my head around the numbers...is there anywhere on the net that has a good thorough description about a process like this?

Hello to everyone. This email will probably be quite lengthy so please bear with me. What I am asking is quite important to me, so I will try to be as detailed as possible.

I have spent the last hour pouring over this list's archive. I have found some great information and a lot of you appear to be quite helpful. I just want to thank everyone in advance for their help. If I have missed something obvious or my question is redundant, then please point me towards the appropriate links and I will read them right away.

I, along with several other people am starting a business which will depend heavily on its web presence. Unfortunately, I am in the all too common position of having to make technical decisions that will have repercussions on the future well-being of said business, with little to no budget. It is crucial that the solution I pick, handle what we hope will become a very large load in the not-to-distant future (whether this happens or not is a question for another day, heh). To this end, I am very interested in using the LAMP (Linux+Apache+MySQL+PHP) approach. I have experience with all of these technologies, but I am definitely not in a position to vouch for their worthiness for use in a large scale application running beneath a heavy load.

To quantify LAMP's ability, is it appropriate for say, sites that generate on the order of 5 million unique hits per day? If not, where would you draw the line? At 500,000? Or 1 million? If so, how much higher could it go possibly? 10 million? 20?

Keep in mind that we have no problem heavily optimizing the application (code tweaks, cacheing, etc).

We looked into and even began development in JSP w/ Tomcat but found Tomcat to be exceedingly unstable for production use (not that it was ever really meant for it). And of course, the other available application servers were well beyond our budget. Also, time constraints have forced us to look for a faster-to-develop alternative.

Just a couple of details about the application we intend to develop. It will be very database intensive (many queries per page) and will also provide real-time payment support (for which transactions are a must).

So, what say you? Given all that I have said, is LAMP appropriate? Will PHP and maybe even more importantly, MySQL be able to scale well? I have no doubt that MySQL is fast, but just how scaleable is it? Will it die beneath the kind of loads I have described?

What would be *most* helpful to me is if you could provide web sites that exist currently and experience this load and are using LAMP (http://www.sourceforge.net?).

I hope you are still with me! Thanks a lot for taking the time to read this and I would appreciate greatly any help that can provide.

Thanks.

It's really difficult to answer this question without knowing a lot more about your application. But as a casual guess, if you reach that sort of traffic level, I'd say your stumbling block is going to by MySQL. At some point - granted, that point can be far away if you design your database and queries well - it will buckle under load.

I'm too busy actually working, unfortunately, to pay attention to the bleeding edge developments in MySQL. But as it stands, there's no serious support for clustering, which means that when you are pushing more transactions than can be handled by the most expensive single machine you can afford, you've hit a brick wall. And as you know, there is a point after which multiple lesser-powered machines are a whole lot cheaper than a single mighty one.

If your database transactions are mostly read-only, and you can segregate the infrequent write transactions to a separate server, you can do jury-rigged replication of the main data store and scale indefinitely.

Otherwise, you'll probably have to plan with an eye to a migration path toward Oracle, DB2, or whatever. This doesn't mean you can't start out with MySQL, but it does mean you should develop with a database abstraction layer and shouldn't depend on features that are fast in MySQL but poorly supported by other databases (or emulated in the abstraction layer).

As for Linux, Apache, and PHP, there's no limit to the transaction volume you can handle with even rudimentary load-balancing tactics, so that's nothing to worry about.

attached mail follows:

Given enough hardware and an appropriately designed application, yes you will be able to scale up as high as you want to go. The big questions are how much money can you spend vs. what performance, stability and fault tolerance do you want out?

You have lots of options - Three or four large smp web servers and a one or two replicated mysql servers in a round robin configuration or dozens of moderately powerful servers running both web server and mysql server with a smart load balancing switch in front.

Both have advantages and disadvantages. Partly it depends on how you write the application, how many sql calls per page you make, how many are writes vs. reads. It may also make sense to write it into a multi tiered app, having the web server make calls to a dedicated php app server that in turn talks to the database server.

I have ways I like to do things, but it really comes down to what you can afford dollar wise, complexity wise, uptime wise and management wise.

Start doing some research and testing. Can PHP and MySQL do that? Sure. Are there better solutions? Sure. Too many factors go into decisions like this that's it not a simple email question and answer.

For one, MySQL only supports transactions if you use InnoDB tables. How reliable are they? I don't know, you'll have to look into it. Do you have a good programmer? If you have a programmer that can write efficient code, then almost any program can be done in PHP. If you get a crappy programmer, then even a simple script can bring your server to it's knees with a little traffic.

Questions like this are posed every day and there are ariticles all over out there that discuss the benifits and disadvantages. Do some searching on Google.

Good luck.

Last night, I ran into a problem when using the MS SQL support in PHP under Apache/PHP module/MS SQL 2000. Everything worked well enough. I was able to connect to the server, query data, and a number of other things. However, I found that if I ran my test page (it connects to, queries and displays 20 rows of data, then disconnects) over and over very quickly (hold CTRL+R down basically) PHP would eventually (after about 6 seconds) fail to connect to the MS SQL server. In fact, the web server would have to be completely restarted before it could connect again.

Has anyone run into this? I mean, if there is no solution to this and is the cause of basically shaky MS SQL support, then the SQL server would be made useless for sites with even a modest amount of traffic (several requests per second). Is this a known problem? If so, could anyone help me out?

Thanks!

Hiya, were you using the appropriate free_query & close functions to free up the memory & more importantly the socket used to talk to the sql server?

You might want to try using the _pconnect function if it's available instead of the usual _connect statement.

I'd guess that PHP ran out of sockets to make outbound connections with. Also, I believe that MSSQL is setup to only have around 1000 max connections open unless you alter the value in the config.

I have been looking through the documentation for using Bzip2 or zlib compression and have a couple of questions for the group...

1. Which is best to use on terms of: resultant file size, availability of decompression clients & ease of use?

2. Both bzip & zlib documentation makes use of *write() functions to add strings to the file, but can this be used to add files?

3. I intend to add two or more zip files to the archive so that the client only needs to download one file rather than several- which is most suited to this - zlib or bzip2?

File size: bzip2 wins, hands down Client availability: zlib wins, hands down Easy of use: tie.

Im still green with writing with class, but I just want to check with you all. I started creating a class file that also using 2 other classes. class.php ----------------------------------- <?php

class foo { function foo() { require_once('./this.class.php'); $this->db_obj = &new abc($db);

require_once('./that.class.php'); $this->tpl_obj = &new xwy; } }

?> ----------------------------------

Then in my actual page I started this ---------------------------------- <?php

require_once('./class.php'); $bar = new foo();

$bar->db_obj->run_some_code($bar); $bar->tpl_obj->do_this_for_me($bar);

?> ------------------------------------

It works but was wondering if its 'legal' to use it like this -> $lcre->db_obj->run_some_code($bar); $lcre->tpl_obj->do_this_for_me($bar);

Im not extending the classes, just using them, so is what Im doing ok?? Thanks

I believe so - but why are you passing a the object a reference to itself?

If you need to access parts of the object from within, use the $this-> pointer.

> It works but was wondering if its 'legal' to use it like this -> > $lcre->db_obj->run_some_code($bar); > $lcre->tpl_obj->do_this_for_me($bar);

This looks like it makes more sense as you are passing a reference to $bar into $lcre - as long as your function is setup to accept this type of object and knows what to do with it.

actually:

If the php directive register_globals is on, then $HTTP_REFERER will exist. Otherwise it will not. (or course that assumes a value exists at all).

Regardless of the register_globals setting, you can do:

// Works since PHP 3 (forever)* print $HTTP_SERVER_VARS['HTTP_REFERER'];

// Works since PHP 4.1.0 print $_SERVER['HTTP_REFERER'];

Btw, $GLOBALS['HTTP_REFERER'] === $HTTP_REFERER. And lastly, since PHP 4.2.0 the register_globals directive defaults to off, which is what Jim was indirectly referring to. See also extract().

Regards, Philip Olson

* For versions older then 4.0.3 see also the track_vars directive, it should be on.

Another similar way, using an array (very simple to add tasks):

$tasks = array('ShowVersion','GetData','CreateImage');

if (in_array($_REQUEST['Task'], $tasks)) { // add some error checking here (function_exists()) $$Task(); } else { // maybe run a default task here print "unknown task"; }

Am using in case 'Task' doesn't exist at all, so no error will be seen (undefined variables create E_NOTICE level errors). Although you may want to check this before Task even reaches in_array(), with empty(). See also:

http://www.php.net/error_reporting

$$Task() is a variable function:

http://uk.php.net/manual/functions.variable-functions.php

And $_REQUEST is a PHP predefined/reserved variable that contains a mix of Get, Post and Cookie data. This may or may not be appropriate here: http://au.phpz.net/manual/language.variables.predefined.php

On a sidenote (picky), consider making variables all lowercase. Also when printing a single var, no need to surround it with quotes. print $foo.

Good day,

I don't have a piece of code off the top of my head, but you'll get lots of results and examples if you enter those variables into www.php.net 's search field and search the online documentation (which is very, very good, I should add).

Hi all,

anyone know of any good pre-written classes or functions to work with IP address space?

I'm looking for things which can verify correct notation of IP addresses (fine, that's easy enough), but also verify things like network addresses, broadcast addresses, and work out subnet masks when a start and end IP address is given...

Any ideas? I'm sure I can just write my own... But it's going to save me allot of time if something like this is out there already for me to use.

ip2long and long2ip and a bit of bitwise logic is really all you need.

I just tried to open the PHP link about the Navy. I'm running IE6 (freshly installed today, so no tweaks have been made) with Win2000. When I clicked on the link in the email, a "locate link" window came up (similar to an open file window). This does not happen on my coworker's machine. The only obvious difference between my computer and my coworker's computer is that I'm running Office XP and he's got Office 2000, so we've got different versions of Outlook.

We are currently redoing our website so that the URL has all of the unique identifiers for each graph, so the whole point is to have people graph something, copy it into an email, and send it to someone so they get the same graph.

Does this happen to anyone else? Is there something we can do to prevent it from happening?

Thanks!

Natalie, I'm using Outlook XP here and the link opens just fine. The only time I get that "locate link browser" window is if I hold the shift-key down when clicking on the link. (I typically link to open links in new windows, so I hold the shift-key when clicking links - It will open the link in a new browser window.)

If you weren't hitting the shift-key, it could be possible that one of your shift-keys are stuck, which is "emulating" the shift-click. Not much more I can tell you other than that, since the link (and all others) work just fine for me in Outlook XP.

My shift key isn't stuck. I don't know what's wrong. I found out that one other person had a problem with it at my company and apparently one of the techies put it on MS's technet group. Hopefully something will come of it.

Thanks for your help!
