Pulling Image Source from HTML

[r0nd3L]

Hi,

 

I haven't done PHP in a while and never got around to learning string matching patterns and what not.

 

What I'm trying to do, is use preg to pull out an img src from HTML website.  This proves rather hard as there are a lot of images and I need specific one.  What helps is that the image all the time ends in pgallery.jpg, so that's something I need to fish for.

 

Here is a sample IMG src from a website: 

 

<img src="image.php?i=2091_paugust/2091_pgallery.jpg" id="i_vv4-35" height="300" width="300">

 

Is this even possible to do?  Thanks!

Try this:

 

<?php
//$str contains the source code
preg_match('~<img\b[^>]+src="([^"]*pgallery.jpg)"~i', $str, $match);
echo $match[1];
?>

 

It searches for the first img tag, where the value of the src attribute ends in pgallery.jpg.

Thanks, that works brilliantly!

 

I'll have to look into learning those patterns, they're too useful.
