Pattern match and extract.

[Kudose]

Hello all.

I am kinda lost when it comes to regular expressions. Can someone point me to a site that will help me accomplish the following:

I need to read a long string, and put all the matches of a string into an array for further use. I dont need any of the other content except the match.

The string I need to match in a HTML string is "&car_id=[0-9]&"

I just need to learn how to extract that entire variable, I can remove the &'s. 🙂

TIA.

[man]preg_match_all()[/man]

preg_match_all('/&(car_id=[0-9])&/', $string, $matches);
print_r($matches);

I can't remember exactly how the matches array is organized but I do remember that the manual entry explains it pretty well.
