Are there alternative methods or libraries that can be used to obtain MAC addresses in PHP on a Linux server?
To obtain MAC addresses in PHP on a Linux server, you can use the `exec()` function to run a command that retrieves the MAC address from the system. One common command to achieve this is `ifconfig`. By executing this command and parsing the output, you can extract the MAC address information.
<?php
// Execute ifconfig command to get MAC address
$macAddress = shell_exec("/sbin/ifconfig | grep 'ether' | awk '{print $2}'");
echo "MAC Address: " . $macAddress;
?>
