Simple Array Problem

[96turnerri]

hi am having problems with this it just doesnt work


<?php

$ip = $_SERVER["REMOTE_ADDR"];
$banned = file("ips.php");

$num = 0;
while(array_key_exists($num, $banned)) {
if($banned[$num] == $ip) {
exit("You Have Been Banned From This Chat Room1");
} else {
echo $banned[$num]."<br>";
}
$num++;
}

if(in_array($ip, $banned)) {
exit("You Have Been Banned From This Chat Room2");
}

echo $ip."<br>";
print_r($banned);

?>


but why? simple simple php, i have just coded a 78kB command file for this and now i come to do something comparativly trivial 'IP blocking' its not working, any ideas?

from the docs:

Note: Each line in the resulting array will include the line ending, so you still need to use rtrim() if you do not want the line ending present.

you may need to use this as 168.12.124.21\n does not equal 168.12.124.21 .

final code
<?php
$ip = $_SERVER["REMOTE_ADDR"]."\n";
$banned = file("ips.php");
if(in_array($ip, $banned)) {
exit("You Have Been Banned From This Chat Room");
}
?>

Me too, PHP has more built-in global functions than you can shake a stick at.
