max wrote a fix for satch666's function, but it too has a little bug... If you write IP
09.111.111.1, it will return TRUE.
<?
$num="(\\d|[1-9]\\d|1\\d\\d|2[0-4]\\d|25[0-5])";
/*
\\d => numbers 0-9
[1-9]\\d => numbers 10-99 --> Here was the bug in max's code
1\\d\\d => numbers 100-199
2[0-4]\\d => numbers 200-249
25[0-5] => numbers 250-255
*/
if (!preg_match("/^$num\\.$num\\.$num\\.$num$/", $$ip_addr)) echo "Wrong IP
Address\\n";
?>
P.S. Why did you write [0-9] and not \\d?
