hey,
i'm trying to convert some special combination to images...

it's my first time i'm try to use regular expressions...

for example, assume that the var $txt contain this:

<p>
sad <{img_2}> asd
</p>

i want the output will be 2
i want all the content that comes before and after the number 2 will removed...
and its important to me to replace the "<" and ">" with "&lt;" and "&gt;"

i tried this:

$img_id = preg_replace("/^(.+?)\<{img_(.+?)\}>(.+?)\$/", "\\2", $txt );

but its wont work!

thanks!

***sorry for poor english***

Why would you care if html is converted to entities if it's being ignored?

PHP Code:

// Use if you want to convert html entities
$txt = htmlentities($txt);
$img_id = (int)preg_replace('/(<|&lt;){img_(\d+)}(>|&gt;)/i', '$2', $txt, 1);
