satch666 writed fix for the function valid_ipv4(), but it's not working good. I think that this
code is realy functionaly.
<?
$num="([0-9]|[0-9]{2}|1\d\d|2[0-4]\d|25[0-5])";
/*
[0-9] => numbers 0-9
[0-9]{2} => numbers 0-99 --> This is missing in satch666 code. It means, that if you write IP
25.213.110.1 function return FALSE!
1\d\d => numbers 100-199
2[0-4]\d => numbers 200-249
25[0-5] => numbers 250-255
*/
if (!preg_match("/^$num\.$num\.$num\.$num$/", $$ip_addr)) echo "Wrong IP
Address\n";
?>
