Add code to remove \r\n or \n in each line be for explode '-'

And also save output to text file.

<?php

$file = file('ips.txt');
$data = "";
foreach ($file AS $line) {

    $ip_range = str_replace(array("\r\n","\r"),"",$line); /* remove \r\n or \n before explode '-' */

    $ips = explode('-', $ip_range);
    $range_one = $ips[0];
    $range_two = $ips[1];

    $ip1 = ip2long ($range_one);
    $ip2 = ip2long ($range_two);

    while ($ip1 <= $ip2) {
        $data .= (long2ip($ip1) ."". "\n"); /* save each line to string */
        $ip1 ++;
    }
}

print_r ($data);
file_put_contents("ips_list.txt", $data); /* save output to text file */

?>
