preg_split url with a regular expression

Question

I have an string e.g.:

src="http://www.domain.com/sub_folder/xyz_17215_andso_on_01-file_08.html"

and want to split this at every character that is not a letter or number.

With

/[a-z0-9]/

I get an array with all the characters but what's the opposite of it to get all the words and numbers?

you may like [parse_url()](http://www.php.net/manual/en/function.parse-url.php) — zb', Nov 24 '12 at 00:23

You can write:

$result_array = preg_split('/[^a-z0-9]+/', $string_to_split);

So simple... I tried this, too but with the ^ outside the []. I think I will never learn this regular expressions. Thank you. :) – netS Nov 24 '12 at 00:35
@netS: You're welcome! Regarding `^`: `[^...]` means "any character other than `...`. But outside `[...]`, `^` means "start of string" (or sometimes "start of line"). – ruakh Nov 24 '12 at 01:00

Rather than writing new code to solve a problem, use the built-in functionality that PHP provides to you in the parse_url() function: http://php.net/manual/en/function.parse-url.php
