How can PHP developers ensure that Wake-on-LAN functionality works seamlessly with the use of UDP packets instead of TCP packets?

To ensure that Wake-on-LAN functionality works seamlessly with the use of UDP packets instead of TCP packets, PHP developers can use the `socket_sendto` function to send the magic packet to the target device's MAC address. This function allows developers to specify the protocol as UDP and send the packet to the correct port. 

$macAddress = '00:11:22:33:44:55';
$macHex = str_replace(':', '', $macAddress);
$magicPacket = hex2bin('FFFFFFFFFFFF' . str_repeat($macHex, 16));

$socket = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
socket_sendto($socket, $magicPacket, strlen($magicPacket), 0, '255.255.255.255', 7);
socket_close($socket);
