PHP remove characters after last occurrence of a character in a string

Question

So the test case string may be:

http://example.com/?u=ben 

Or

http://example.com 

I'm trying to remove everything after the last occurrence of a '/' but only if it's not part of the 'http://'. Is this possible!?

I have this so far:

$url = substr($url, 0, strpos( $url, '/')); 

But does not work, strips off everything after first '/'.

Answer 1

You must use strrpos function not strpos ;-)

substr($url, 0, strrpos( $url, '/')); 

Answer 2

You should use the tool that is designed for this type of job, parse_url

url.php

<?php  $urls = array('http://example.com/foo?u=ben',                 'http://example.com/foo/bar/?u=ben',                 'http://example.com/foo/bar/baz?u=ben',                 'https://foo.example.com/foo/bar/baz?u=ben',             );   function clean_url($url) {     $parts = parse_url($url);     return $parts['scheme'] . '://' . $parts['host'] . $parts['path']; }  foreach ($urls as $url) {     echo clean_url($url) . "\n"; } 

Example:

·> php url.php                                                                                                  http://example.com/foo http://example.com/foo/bar/ http://example.com/foo/bar/baz https://foo.example.com/foo/bar/baz
