Are there alternative methods, aside from using nmap, to ping the network and store the results for comparison in PHP?

One alternative method to ping the network and store the results for comparison in PHP is to use the `exec()` function to execute the `ping` command in the terminal and capture the output. You can then parse the output to extract the necessary information for comparison.

<?php
// Execute the ping command and capture the output
exec("ping -c 4 192.168.1.1", $output);

// Parse the output to extract the necessary information
$pingResults = implode("\n", $output);

// Store the results for comparison
file_put_contents('ping_results.txt', $pingResults);
?>
