Now I have it like so:
<?
$url=$_SERVER['REQUEST_URI'];
$requred_string= substr(strrchr($url, "/"), 1);
?>
and it returns the last segment, but it also returns all the ?p=y&g=x gibberish that I don't need. How can I slice off the $_GET variables?
You can use strtok to exclude the query strings:
$url = strtok($_SERVER['REQUEST_URI'], '?');
$requred_string = substr(strrchr($url, '/'), 1);
echo $requred_string;
Or as mentioned in the comments, parse_url will work also:
$requred_string = substr(strrchr(parse_url($url)['path'], '/'), 1); // PHP 5.4 or greater with dereference
here's a more elegant way basename(parse_url($url, PHP_URL_PATH))
print_r(parse_url($url));
