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

The parse_url() function and extract the path. Explode on '/' and get the last element

Answer 2

One of the following:

preg_match('~/[^/]*$~', $str, $matches);
echo $matches[0];

Or:

$parts = explode('/', $str);
echo array_pop($parts);

Or:

echo substr($str, strrpos($str, '/'));

Answer 3

Try this

$url = $_SERVER['REQUEST_URI'];
$parsed_url = parse_url($url);
$url_parts = explode('/',$parsed_url['path']);
print_r($url_parts);

Answer 4

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`
