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.

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;

}

?>
