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.
You can use backreferences in regular expressions.
$var= preg_replace('/([a-z]+)/is','$1','azxcvjf937^88');
if($var==='azxcvjf') echo "MATCH";

look at Example1.
