Re: bit wise math? Is there a function to easily return the bits?

[Jon Anderson <jon@xxxxxxxxxxxxxxxxxx>]

function bits($num) {
       $bit_array = str_split(strrev(decbin(intval($num))));
       $val_array = array();
       foreach ($bit_array as $pow => $bit) {
               if ($val = $bit * pow(2,$pow))
                       $val_array[] = $val;
       }
       return($val_array);
}

(I wanted to see if I could write it in few LOC.) I wonder if there's a 
faster way...
