[SOLVED] remove trailing slash

[heavyEddie]

OK, I can't see any reason that this line of code isn't working.  It is intended to remove a trailing slash if it exists... but it doesn't.  It seems to work for displaying the string without the trailing slash, but not defining the variable.

 

I have a feeling this is going to be a "DUH" moment.

 

Doesn't work...

if(substr($url, -1) == "/") $url = substr($url, 0, -1);

 

However, this will display what I'm looking for

if(substr($url, -1) == "/") echo substr($url, 0, -1);

try

 

$url = preg_replace("/\/$/","",$url);

That would certainly do it as well, but I found the answer...  In my code I was calling a different variable than what this code was using.

 

Man... I new it would be a stupid answer.

 

If nothing else, folks can now see two methods for removing a trailing slash.  I think I read someplace the using substr was faster than preg_replace.  Not sure if that is accurate though.
