Php and HTML and die() for testing. Page does not die()

Question

The localhost webpage should not display the HTML because in killed the page using die().

I can continue w/o sorting this but I am really curious. Lots of very good info came up as I searched this forum.

According to the tutorial that I am following, The page should die() and not display the words Welcome But it does display welcome at localhost/my website/

Index.php

<?php 
require 'conf.inc.php';

foreach($ip_blocked as $ip){
    if ($ip==$ip_address){
      die();
}
}
?>

<h1> welcome</h1>


conf.inc.php

<?php 

$ip_address = $_SERVER['REMOTE_ADDR'];
$ip_blocked = array('127,0,0,1', '100,100,100,100');
?>

Answer 1

Change

$ip_blocked = array('127,0,0,1', '100,100,100,100');

to

$ip_blocked = array('127.0.0.1', '100.100.100.100');

. instead of ,

Answer 2

$ip_blocked = array('127,0,0,1', '100,100,100,100');

should be

$ip_blocked = array('127.0.0.1', '100.100.100.100');

Notice the DOTs!

Plus you should not compare strings with IPs. Think IPs in terms of ranges, check against private IP addresses if you're on a network with a 192.168.*.* IP address.

ip2long() should be taken into consideration. Numbers compare faster than strings plus friendlier with range comparison (in between) .
