Get only filename from url in php without any variable values which exist in the url

This should work:

echo basename($_SERVER['REQUEST_URI'], '?' . $_SERVER['QUERY_STRING']);

But beware of any malicious parts in your URL.

Following steps shows total information about how to get file, file with extension, file without extension. This technique is very helpful for me. Hope it will be helpful to you too.

  $url = 'https://www.google.com/images/branding/googlelogo/2x/googlelogo_color_120x44dp.png';
        $file = file_get_contents($url); // to get file
        $name = basename($url); // to get file name
        $ext = pathinfo($url, PATHINFO_EXTENSION); // to get extension
        $name2 =pathinfo($url, PATHINFO_FILENAME); //file name without extension

Use parse_url() as Pekka said:

<?php
$url = 'http://www.example.com/search.php?arg1=arg2';

$parts = parse_url($url);

$str = $parts['scheme'].'://'.$parts['host'].$parts['path'];

echo $str;
?>

In this example the optional username and password aren't output!
