$url = 'http://www.domain.com/something/interesting_part/?somevars&othervars';
$parts = explode('/', $url);
echo $parts[4];
Output:
interesting_part

I was just writing this as you posted :D

If 'something' does not have '/' inside then it's the best way to achieve it.
Try:
<?php
$url = 'http://www.domain.com/something/interesting_part/?somevars&othervars';
preg_match('`/([^/]+)/[^/]*$`', $url, $m);
echo $m[1];
You should use parse_url to do operations with URL. First parse it, then do changes you desire, using, for example, explode, then put it back together.
$uri = "http://www.domain.com/something/interesting_part/?somevars&othervars";
$uri_parts = parse_url( $uri );
/*
you should get:
array(4) {
["scheme"]=>
string(4) "http"
["host"]=>
string(14) "www.domain.com"
["path"]=>
string(28) "/something/interesting_part/"
["query"]=>
string(18) "somevars&othervars"
}
*/
...
// whatever regex or explode (regex seems to be a better idea now)
// used on $uri_parts[ "path" ]
...
$new_uri = $uri_parts[ "scheme" ] + $uri_parts[ "host" ] ... + $new_path ...

If the interesting part is always last part of path:
echo basename(parse_url($url, PHP_URL_PATH));
[+] please note that this will only work without index.php or any other file name before ?. This one will work for both cases:
$path = parse_url($url, PHP_URL_PATH);
echo ($path[strlen($path)-1] == '/') ? basename($path) : basename(dirname($path));

Here is example using parse_url() to override the specific part:
<?php
$arr = parse_url("http://www.domain.com/something/remove_me/?foo&bar");
$arr['path'] = "/something/";
printf("%s://%s%s?%s", $arr['scheme'], $arr['host'], $arr['path'], $arr['query']);
