Remove Trailing Slash From String PHP

Is it possible to remove the trailing slash / from a string 开发者_如何转开发using PHP?

Sure it is, simply check if the last character is a slash and then nuke that one.

if(substr($string, -1) == '/') {
    $string = substr($string, 0, -1);
}

Another (probably better) option would be using rtrim() - this one removes all trailing slashes:

$string = rtrim($string, '/');

This removes trailing slashes:

$str = rtrim($str, '/');

Long accepted, however in my related searches I stumbled here, and am adding for "completeness"; rtrim() is great, however implemented like this:

$string = rtrim($string, '/\\'); //strip both forward and back slashes

It ensures portability from *nix to Windows, as I assume this question pertains to dealing with paths.

rtrim Use rtrim cause it respects the string doesnt end with a trailing slash

Yes, it is!
