Extract specific part of a string in PHP

Question

I was simply wondering what would be the simplest and most efficient way of extracting a certain part of a dynamic string in PHP?

Per example, in this string:

<

Answer 1

Try parse_url over regex:

$segments = explode('/', parse_url($url, PHP_URL_PATH));

$segments will be an array containing all segments of the path info, e.g.

Array
(
    [0] => 
    [1] => video
    [2] => xclep1_school-gyrls-something-like-a-party_music
)

So you can do

echo $segments[2];

and get

`xclep1_school-gyrls-something-like-a-party_music`
