in_array() help

[waverider303]

I want to create an if statement that will check through an array for a specific ip address (kind of a anti spam system).

 

<?php
/*
*$usr_ip - is the ip address pulled from the form
*$banned_ip - is the array of ip address's to search through
*/
if (in_array($usr_ip, $banned_ip)) {
	die("Banned User!");
} else {
}
?>

 

Shouldnt This work?

yes

 

But depending on how you generate the array, and how many entries there are, it may be faster to store the IP's on a database and do a query
