Sending data using UDP

I want to send the following data using UDP.


$packet[0] = 0x01;
$packet[1] = 0x11;
$packet[2] = 0xF1;
$packet[3] = 0xD1;
$packet[4] = 0xF1;
$packet[5] = 0xB1;
$packet[6] = 0xC1;
$packet[7] = 0xF1;


I used int socket_sendto ( resource $socket , string $buf , int $len , int $flags , string $addr [, int $port = 0 ] ) function to send.


But it accepts a string.How can i convert interger array and send data to UDP server, So that data is treated as 1 byte each.


Thanks.

 

loop the array? or add all packets to a string and give each array item a EOF! or something.
