In php-5.2.0, there's no MSG_EOF anymore. This is not even needed if you make sure you handle writes and close of sockets correctly.
(PHP 4 >= 4.1.0, PHP 5, PHP 7)
socket_send — Sends data to a connected socket
$socket
, string $buf
, int $len
, int $flags
)
The function socket_send() sends
len bytes to the socket
socket from buf.
socketA valid socket resource created with socket_create() or socket_accept().
bufA buffer containing the data that will be sent to the remote host.
len
The number of bytes that will be sent to the remote host from
buf.
flags
The value of flags can be any combination of
the following flags, joined with the binary OR (|)
operator.
MSG_OOB |
Send OOB (out-of-band) data. |
MSG_EOR |
Indicate a record mark. The sent data completes the record. |
MSG_EOF |
Close the sender side of the socket and include an appropriate notification of this at the end of the sent data. The sent data completes the transaction. |
MSG_DONTROUTE |
Bypass routing, use direct interface. |
socket_send() returns the number of bytes sent, or FALSE on error.

I changed the Magic Packet function to this. I beleave that an function may not return any value, only an true/false (in the most way's).
<?PHP
function wol_magic_packet($mac,$addr='255.255.255.255') {
//Requirements__________________________
// You need to load the php_sockets.dll (in case of Windows, don't
// know @ linux, compile with --socket-support i beleave ).
// Otherwise he cannot find the socket_create function
//Usage________________________________
// $addr:
// You will send and broadcast tho this addres.
// Normaly you need to use the 255.255.255.255 adres, so i made it as default. So you don't need
// to do anything with this.
// $mac:
// You will WAKE-UP this WOL-enabled computer, you need to add the MAC-addres here.
//
//Return________________________________
// TRUE: When socked was created succesvolly and the message has been send.
// FALSE: Something went wrong
//
//Example_1_____________________________
// When the message has been send you will see the message "Done...."
//
// if ( wol_magic_packet ( '00:00:00:00:00:00' ) )
// echo 'Done...';
// else
// echo 'Error while sending';
//
//Example_2_____________________________
// To loop more computers:
//
// $arr = array(
// '00:00:00:00:00:00',
// '00:00:00:00:00:00'
// );
// foreach($arr as $this_id => $this_mac)
// if (! wol_magic_packet ( $this_mac ))
// echo 'Error while sending to ['. $this_mac .']<br />'."\r\n";
//___________________________________________
//Check if it's an real MAC-addres and split it into an array
if (!preg_match("/([A-F0-9]{2}[-:]){5}[A-F0-9]{2}/",$mac,$maccheck))
return false;
$addr_byte = preg_split("/[-:]/",$maccheck[0]);
//Creating hardware adress
$hw_addr = '';
for ($a=0; $a < 6; $a++)//Changing mac adres from HEXEDECIMAL to DECIMAL
$hw_addr .= chr(hexdec($addr_byte[$a]));
//Create package data
$msg = str_repeat(chr(255),6);
for ($a = 1; $a <= 16; $a++)
$msg .= $hw_addr;
//Sending data
if ( //If
function_exists('socket_create') AND //socket_create exists
$sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP) AND //Can create the socket
$sock_data = socket_connect($sock, $addr, 2050) //Can connect to the socket
) { //Then
$sock_data = socket_set_option($sock, SOL_SOCKET, SO_BROADCAST, 1); //Set
$sock_data = socket_write($sock, $msg, strlen($msg)); //Send data
socket_close($sock); //Close socket
return true;
} else //Esle? :P
return false;
}
