Checking if date is weekend PHP

Question

This function seems to only return false. Are any of you getting the same? I'm sure I'm overlooking something, however, fresh eyes and all that ...

function isweekend($date){     $date = strtotime($date);     $date = date("l", $date);     $date = strtolower($date);     echo $date;     if($date == "saturday" || $date == "sunday") {         return "true";     } else {         return "false";     } } 

I call the function using the following:

$isthisaweekend = isweekend('2011-01-01');

If you have PHP >= 5.1:

function isWeekend($date) {     return (date('N', strtotime($date)) >= 6); } 

otherwise:

function isWeekend($date) {     $weekDay = date('w', strtotime($date));     return ($weekDay == 0 || $weekDay == 6); }
