best way to remove trailing slashes in urls with php

Question

i have some urls

www.amazon.com/
www.digg.com
www.microsoft.com/

etc. i want to remove the trailing slash. so not just the last character. is there a trim or rtrim for this? or something fast?

Answer 1

You put rtrim in your answer, why not just look it up?

$url = rtrim($url,"/");

As a side note, look up any PHP function by doing the following:

• http://php.net/functionname
• http://php.net/rtrim
• http://php.net/trim

Answer 2

$urls="www.amazon.com/ www.digg.com/ www.microsoft.com/";
echo preg_replace("/\b\//","",$urls);
