note 43057 added to function.socket-create

Seems there aren't any examples of UDP clients out there. This is a tftp client. I hope this makes someone's life easier. <?php function tftp_fetch($host, $filename) { $socket = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP); // create the request packet $packet = chr(0) . chr(1) . $filename . chr(0) . 'octet' . chr(0); // UDP is connectionless, so we just send on it. socket_sendto($socket, $packet, strlen($packet), 0x100, $host, 69); $buffer = ''; $port = ''; $ret = ''; do { // $buffer and $port both come back with information for the ack // 516 = 4 bytes for the header + 512 bytes of data socket_recvfrom($socket, $buffer, 516, 0, $host, $port); // add the block number from the data packet to the ack packet $packet = chr(0) . chr(4) . substr($buffer, 2, 2); // send ack socket_sendto($socket, $packet, strlen($packet), 0, $host, $port); // append the data to the return variable // for large files this function should take a file handle as an arg $ret .= substr($buffer, 4); } while(strlen($buffer) == 516); // the first non-full packet is the last. return $ret; } ?> ---- Manual Page -- http://www.php.net/manual/en/function.socket-create.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+43057 Delete -- http://master.php.net/manage/user-notes.php?action=delete+43057&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+43057&report=yes Search -- http://master.php.net/manage/user-notes.php
