I have some URLs, like www.amazon.com/
, www.digg.com
or www.microsoft.com/
and I want to remove the trailing slash, if it exists, so not j
I came here looking for a way to remove trailing slash and redirect the browser, I have come up with an answer that I would like to share for anyone coming after me:
//remove trailing slash from uri
if( ($_SERVER['REQUEST_URI'] != "/") and preg_match('{/$}',$_SERVER['REQUEST_URI']) ) {
header ('Location: '.preg_replace('{/$}', '', $_SERVER['REQUEST_URI']));
exit();
}
The ($_SERVER['REQUEST_URI'] != "/")
will avoid host URI e.g www.amazon.com/ because web browsers always send a trailing slash after a domain name, and preg_match('{/$}',$_SERVER['REQUEST_URI'])
will match all other URI with trailing slash as last character. Then preg_replace('{/$}', '', $_SERVER['REQUEST_URI'])
will remove the slash and hand over to header()
to redirect. The exit()
function is important to stop any further code execution.
