IP and PHP Help

[canadezo]

How can you use IP validation saved from a text file? Here's an example of what I'm trying to do...

<?php
if IP 'InternetProtocal.txt' , then it script allows to view the page;

else   show message like "you don't have permision to view this page";


?>

I do understand that above will not work; it's just so you can get an idea of my goal...

$i = 0;
$ip = $_SERVER['REMOTE_ADDR'];
$file = fopen('InternetProtocol.txt', 'r');

while(!feof($file)) {
if(fgets($file) == $ip) {
	$i = 1;
}
}

if($i == 1) {
echo "You may view this page.";
} else {
echo "You may not view this page...";
}

fclose($file);

I'm assuming InternetProtocal.txt has a list of valid ip's and that they are seperated by a semicolon (

 

so, first you need to read that file and put all the addresses in an array

$file =file_get_contents('InternetProtocal.txt');
$ips_on_file = explode(";",$file);

 

next, grab the clients IP address and check to see if it exists in you list:

$client_ip = $_SERVER['REMOTE_ADDR'];
if(in_array($client_ip,$ips_on_file)){
// OK TO PROCEED
}else{
// NO ACCESS
}

 

Hope this helps
