Good points, I'll try it.

In case you want to check it tomorrow or later:
private function binstr() {
$temp_bits = $this->bits;
$str = "";
for ($i=0;$i<32;$i++) {
$str = strval($temp_bits & 1) . $str;
$temp_bits >>= 1;
}
return $str;
}
it doesn't accept parameters, but instead use private field $bits assigned
to $temp_bits (PHP manual states that it will be copied instead of
referenced, and it's exactly what I need).
