Answer 1

Just figured it out.This now works with

$r = $_SERVER['REQUEST_URI']; 
$r = explode('/', $r);
$r = array_filter($r);
$r = array_merge($r, array()); 
$r = preg_replace('/\?.*/', '', $r);

$endofurl = $r[1];
echo $endofurl;

Answer 2

You can use PHP's parse_url() function to split the URL for you and then access the path parameter and get the end of it:

$r = parse_url($url);
$endofurl = substr($r['path'], strrpos($r['path'], '/'));

This will parse the URL and then take a "sub-string" of the URL starting from the last-found / in the path.

You can alternatively use explode('/') as you're currently doing on the path:

$path = explode($r['path']);
$endofurl = $path[count($path) - 1];

UPDATE (using strrchr(), pointed out by @x4rf41):
A shorter method of obtaining the end of the string, opposed to substr() + strrpos() is to use strrchr():

$endofurl = strrchr($r['path'], '/');

If you take advantage of parse_url()'s option parameters, you can also get just the path by using PHP_URL_PATH like $r = parse_url($url, PHP_URL_PATH);

Or, the shortest method:

$endofurl = strrchr(parse_url($url, PHP_URL_PATH), '/');

Answer 3

If you want to retrieve the last element of the array, you can use the end function. The rest of your code seems to be working.

$endofurl = end($r);

You could also leverage parse_url and strrchr functions to make it more concise:

$endofurl = strrchr(parse_url($url, PHP_URL_PATH), '/');
