Best way to remove trailing slashes in URLs with PHP

Question

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

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

(rtrim stands for 'Right trim')
