socket_send

Sends data to a connected socket (PHP 4 >= 4.0.7, PHP 5)
int socket_send ( resource socket, string buf, int len, int flags )

The function socket_send() sends len bytes to the socket socket from buf.

Parameters

socket

A valid socket resource created with socket_create() or socket_accept().

buf

A 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.

Table 298. Possible values for `flags`

`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.

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.
