How to get number of characters from var?

[David vd Geer Inhuur tbv IPlib]

Hi,

I have a question about determine how many charactars contain a var. 
Does anyone know, there will probably be a simple command, but I can't find it.

Assuming $_ = /hello/this/will/have/to/be/IMPORTANT/ONLY/AND/CAN/BE/LONG/features.txt

        $dir = substr("$_", 0, -13);  ## Remove features.txt
        $link = substr("$dir", 27);  ## Remove the not used and already defined $base
        @href = split(/\//, $link);  ## put this in an array
        $lineteller = ( scalar(@href) -1 );  ## To determine the last word
        $href = "$href[${lineteller}]"; ## and make $href this last one
        
        $nhref = ???($href);    ?? Determine number of characters
        $header = substr("$link", 0, -${nhref});  ## Use it to def $header without 
$href
        
So what I need out of $_ :

 $dir = "/hello/this/will/have/to/be/IMPORTANT/ONLY/AND/CAN/BE/LONG";
 $link = "/IMPORTANT/ONLY/AND/CAN/BE/LONG";
 $href = "LONG";
 $header = "/IMPORTANT/ONLY/AND/CAN/BE/";
 
I know there is a faster way to get the last value of an aray, but I don't know
exactly how anymore (help is welcome). The most important now is, how do I get
the number of charactars out of $href ??

Thanks for your help in adance !!
