What is the purpose of assigning names to MAC addresses in the given PHP code?

Assigning names to MAC addresses in the given PHP code allows for easier identification and organization of devices on a network. This can be particularly useful in situations where multiple devices are connected and need to be managed efficiently. By assigning names to MAC addresses, administrators can quickly identify specific devices and perform necessary actions such as troubleshooting or configuration changes. 

// Create an associative array to store MAC addresses and their corresponding names
$devices = [
    "00:0a:95:9d:68:16" => "Device 1",
    "00:1c:23:44:55:66" => "Device 2",
    "00:ab:cd:ef:12:34" => "Device 3"
];

// Function to get the name of a device based on its MAC address
function getDeviceName($macAddress, $devices) {
    if (array_key_exists($macAddress, $devices)) {
        return $devices[$macAddress];
    } else {
        return "Unknown Device";
    }
}

// Example of how to use the getDeviceName function
$macAddress = "00:1c:23:44:55:66";
echo "Device with MAC address " . $macAddress . " is named: " . getDeviceName($macAddress, $devices);
