Hi Pierre, :-O I was just going to give you an example from zend_operators.h, is_numeric_string() and guess what? It's the "correct" way that I thought it should be! I thought PHP 6 changed something, to where /* handle hex numbers */ if (length>=2 && str[0]=='0' && (str[1]=='x' || str[1]=='X')) {
    conv_base=16;
} which is easy to understand :-) became if (length>=2 && str[0]=='' && (str[1]=='x' || str[1]=='X')) {
    conv_base=16;
}
'0' became '' ? Why would _character_ 0 become nothing?
I don't know; was wondering the same thing. :-) But, that is what I saw on http://lxr.php.net :-(

What do you mean "I saw on lxr"? I still don't understand a word.. -- Wbr, Antony Dovgal
