25 * This file contains the basic Client Socket.
27 ************************************************************************
30 * bool connect(String $host, int $port, String $bind = null, bool $ssl = false, int $blocking = 0)
31 * connects the socket to $host:$port with the provided options
34 * disconnects the socket
37 * returns the state of the socket (true if the socket is connected with the server)
40 * tries to receive datas from the socket. Returns null or a array containing the lines received.
41 * this method BLOCKS THE SCRIPT EXECUTION for the defined time if $blocking is set on connect().
43 * void send(String $line, String $newline = "\r\n")
44 * tries to send datas through the socket.
46 * Array[] getTraffic()
47 * returns an array containing the traffic the socket has received and sent.
48 * index in = incoming (received) traffic count
49 index out = outgoing (sent) traffic count
