Hi,

I'm trying to find a way to get part of a string where the part is matched with regular expressions.

So, for example, if I have a string:

a2b3cd5ef6ghi7232jklmn

I need to grab "12b3cd5" using regular expressions and store the part in a variable.

$var = do_something("","","a2b3cd5ef6ghi7232jklmn");

I was using preg_replace for this, and try to delete (i.e., replace the non-matched part with an empty string) the second part, but I can't make it work.
