    [CLEANUP] Replace strlen() with === for zero length check · de27a20a
    Markus Klein authored
    It is faster to compare a string with === '' to find out if it's empty
    than to run strlen() on it.
    
    The replacement rules are applied as follows:
     *    if (strlen($str))
       => if ((string)$str !== '')
     *    if (!is_string($str) || strlen($str) === 0)
       => if (!is_string($str) || $str === '')
     * If it can be seen easily that $str is a string,
       the typecast is omitted.
