How can the code snippet provided be improved to handle multiple IP addresses in the lastip.txt file?

The issue with the current code snippet is that it only reads and processes a single IP address from the lastip.txt file. To handle multiple IP addresses, we can modify the code to read all lines from the file and process each IP address individually. This can be achieved by using a loop to iterate through each line in the file and extract the IP address. 

<?php
$filename = 'lastip.txt';
$handle = fopen($filename, 'r');
if ($handle) {
    while (($line = fgets($handle)) !== false) {
        $ip = trim($line);
        // Process each IP address here
        echo "IP Address: $ip\n";
    }
    fclose($handle);
} else {
    echo "Error opening the file.";
}
?>
