note 18627 added to function.strstr

This may or may not be useful to you .. This one line will get the IP subnet from an IP address, and replace the last octet/field (I obviously don't know the name of it :|) with an asterisk. Let's suppose the IP address of the visitor is 205.215.24.184 $ipsub = strrev(strchr(strrev(getenv("REMOTE_ADDR")), ".")) . "*"; $ipsub will then equal "205.215.24.*" -- http://www.php.net/manual/en/function.strstr.php http://master.php.net/manage/user-notes.php?action=edit+18627 http://master.php.net/manage/user-notes.php?action=delete+18627 http://master.php.net/manage/user-notes.php?action=reject+18627
