[SOLVED] getting to know preg_match(), patterns, and finding first image location string

[ultrus]

Hello,

I'm tweaking a WordPress template to show thumbnails of the first image in each post (if there is one) to represent each blog post link. To do that, I need to search the post HTML content for the first <img ... src='GOLDEN GOAL' ... /> or <img ... src="GOLDEN GOAL" ... />. Once I get the image source sting, I can rip it apart and get the WordPress thumbnail version on the image. This seems daunting at the moment due to a faded memory on patterns.

 

Any clues on how to get started? Keep in mind that the ... in the image tag represent style, alt, class that were added to images in random order. hmmm. *begins brushing up on patterns

 

Thanks for the assist

try

<?php
$a = 'blah m <img >blah<a ><img blah src="aaaa" />sasa <img src=\'ddd"</a>';
preg_match('/<img[^>]+src=[\'"]([^\'"]*)/',$a,$b);
print_r($b);
?>

sasa,

That works like a charm! Thanks for the boost. I'm getting my patterns beefed up again now.
