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 * returns the state of the socket (true if the socket is connected with the server)
37 * tries to receive datas from the socket. Returns null or a array containing the lines received.
38 * this method BLOCKS THE SCRIPT EXECUTION for the defined time if $blocking is set on connect().
40 * void send(String $line, String $newline = "\r\n")
41 * tries to send datas through the socket.
43 * Array[] getTraffic()
44 * returns an array containing the traffic the socket has received and sent.
45 * index in = incoming (received) traffic count
46 index out = outgoing (sent) traffic count
