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? ---- Manual Page -- http://www.php.net/manual/en/function.preg-match.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+52836 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+52836&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+52836&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+52836&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+52836&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+52836&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+52836&report=yes Search -- http://master.php.net/manage/user-notes.php
