unique hit counter using file handling not working properly? - php

Question

There are three files: index.php, ip.txt that contains ip address which are allowed to visit site and count.txt which simply counts the hit if any user visits the site with specified ip addresses in ip.txt. But the problem is when ip.txt contains only my laptops ip local machines ip address, it works perfectly and increases the ip address by one. But when ip.txt contains many ip address along with my local machines ip address if block in foreach loop checks them and and doesn't increase the count. However it should increase the count as my ip address is also there in ip.txt file. Please help!!
index.php:
<?php
$ip_address = $_SERVER['REMOTE_ADDR'];
$handle = fopen('ip.txt','r');
$file_read = fread($handle, filesize('ip.txt'));
$file_read_array = explode('\n',$file_read);
foreach($file_read_array as $ip)
{
if(trim($ip) == trim($ip_address))
{
$visit =true;
echo 'true';
break;
}
else
{
$visit =false;
echo 'false';
}
}
if($visit == true)
{
$handle_1 = fopen('count.txt','r');
$file_read_1 = fread($handle_1, filesize('count.txt'));
$increment = $file_read_1 + 1;
fclose($handle_1);
$handle_2 = fopen('count.txt','w');
fwrite($handle_2,$increment);
fclose($handle_2);
}
else
{
echo 'ip address not found.';
}
?>
ip.txt:
127.0.0.1
100.100.100.100
102.1.1.1
count.txt:
