Get only image url from phpbb post text

Question

Since PHPBB have its own way of calling the inline images, i have post_text something like this

test content [img:32acu135]http://mywebsite.com.pk/wp-content/uploads/2012/10/some-thing-3.jpg[/img:32acu135]

in database, is there any way that i can call the first image in the content, may be using preg_match_all or regex..

Answer 1

I would go for a regex like

\[img.+?\](.*)\[\/img.+?\]

and take the capturing group

php example

$re = "/\\[img.+?\\](.*)\\[\\/img.+?\\]/"; 
$str = "[img:32acu135]http://mywebsite.com.pk/wp-content/uploads/2012/10/some-thing-3.jpg[/img:32acu135]"; 

preg_match($re, $str, $matches);

print($matches[1]);

Result :

http://mywebsite.com.pk/wp-content/uploads/2012/10/some-thing-3.jpg
