Wild Cards in str_replace

[maxudaskin]

Is it possible? If not, is there another way to do it?

 

What I want to do is if <img src="someurl.com/image.jpg" /> is found (the url would vary) to getimagesize("someurl.com/image.jpg"). To do this, we need to extract the URL... is it possible?

 

<?php
$smilies   = array("[img=","]");
$locations = array('<img src="','" />');
echo str_replace($smilies,$locations,nl2br($text));
?>

 

$text might be

Hey,
I found a cool pic!
[img=http://www.url.com/image.jpg]

try

<?php
$text = 'Hey,
I found a cool pic!
[img=http://www.url.com/image.jpg]
bla [img=http://www.url2.com/image2.jpg]';
preg_match_all('/\[img\](.+?)\[\/img\]/', $text, $url);
print_r($url[1]);
?>
