I'm writing a script that retrieves the first image link in a post
$content = [center]Hello World, this is my house: [img]myhouse.png[/img] blah blah blah blah [/center] This is another house [img]anotherhouse.png[/img] , blah blah blah
I would like to just return "myhouse.png" and save it into a variable Also img
should be case insensitive, meaning it would work on [img]text-here[/img]
or [IMG]text-here[/IMG]
This will return the first image:
$content = '[center]Hello World, this is my house: [img]myhouse.png[/img] blah blah blah blah [/center] This is another house [img]anotherhouse.png[/img] , blah blah blah';
preg_match('#\[img\]\s*(?P<png>.*?)\s*\[/img\]#i', $content, $m);
echo $m['png']; // myhouse.png
Here comes a regex:
$content = '[center]Hello World, this is my house: [img]myhouse.png[/img] blah blah blah blah [/center] This is another house [img]anotherhouse.png[/img] , blah blah blah';
$pattern = '/\[img\](.*)\[\/img\]/U'; // <-- the U means ungreedy
preg_match_all($pattern, $content, $matches);
var_dump($matches[1]);
Explanation:
The regex matches everything between a pair of [img] ... [/img]
tags. To make sure that it will not match all text between the first [img]
and the last [/img] tag I've use the ungreedy modifier.
