Sub String Function w/ Int Start AND Int End

[rpanning]

I'm looking for a sub string function that has a int start and int end, NOT int length like substr(). It would be something like JavaScript's substring(). I've been looking for one but havn't found it yet. Just looking for the function. Thanks

Couldn't you just use the actual substr() function, only like this:

substr($string,$start,($end-$start+1));

Or if you use it quite often, just functionize it,

function jsSubstring($string,$start,$end) {
    $length = $end - $start + 1;
    return substr($string,$start,$length);
}

Just an idea..tell me if it works!
