Can anyone do this PERL in PHP? [I suck at pl..]

Manga27

I was trying to get help with a PHP problem here: http://www.phpbuilder.com/board/showthread.php?s=&threadid=10257645

I may have come up with a solution using JavaScript. I stumbled across AXS Hit Tracking Script (which I'm sure many here have used before). Basically, it tracks hits by using this JavaScript code:

<script type="text/javascript">
<!--
	document.write('<img src="/cgi-bin/axs/ax.pl?trans.gif&ref=');
	document.write(document.referrer);
	document.write('" height="1" width="1" alt="" />');
// -->
</script><noscript>
	<img src="/cgi-bin/axs/ax.pl?trans.gif" height="1" width="1" alt="" />
</noscript>

So, apparently his technique is to create an image on the page, where the img src points to a PERL script rather than a real image. And then in the PERL script, he must record where the requests come from.

But I am not a PERL coder. Can anyone show me how/if this same technique can be done in PHP? This would solve my problem in the original thread... and save my a**.

[If you are following the other thread, this would allow me to call the program without using a require...]

Thanks in advance!

So you are trying to keep track of who is linking to your page.
In the page you want to keep track of just store $_SERVER['HTTP_REFERER'], this may not be totally reliable as some browsers don't send this info.

To use the js solution you would need a script like this

<?php
header ("Content-type: image/png");
$im = @imagecreate (1,1)
    or die ("Cannot Initialize new GD image stream");
imagepng ($im);
imagedestroy ($im);


// You  will have to save the $_GET variables sent from the request here

?>

But then, how do you call this image script that you wrote? I tried using this:

and it didn't seem to call the PHP program at all, it just gave me a broken image. This is how the HTML came out:

<HTML>
<BODY>
<img src="track.php?whatever.png" alt="" />
</body>
</html>

Any ideas?

Thanks in advance!
