[PHP] SocksWork - PHP Socket client library

<?php
/**
 * SocksWork example file
 * 
 * This file is made in order to help you understand how SocksWork works
 * First we will instance a SocksWork object and a PacketBuilder object
 * We will use PacketBuilder object to build the packet that will be sent to the server
 * The packet will be like this:
 *         packetID: 1
 *         packetContent: Hello SocksWork!
 * The bytes of packets would be something like this:
 *       PACKET ID  | HELLO SOCKSWORK!
 *    00 00 00 01 00 00 00 16 72 101 108 108 111 32 83 111 99 107 115 87 111 114 107 33
 * The first 4 bytes are packetID:
 *         00 00 00 01 = 1
 * The rest of the packet is the content
 * As the content is just an string first 4 bytes indicates string length:
 *         00 00 00 16 = 16
 * And next bytes are string bytes:
 *         72 101 108 108 111 32 83 111 99 107 115 87 111 114 107 33 = Hello SocksWork!
 * 
 * Once we've sent the packet we will wait for the response
 * Let's assume that the response packet is something like this
 *         packetID = 2
 *         packetContent: Hello!
 * The bytes would be something like this:
 *         PACKET ID  | HELLO!
 *         00 00 00 02 00 00 00 06 72 101 108 108 111 33
 * First 4 bytes are packetID:
 *         00 00 00 02 = 2
 * Next is packet content
 * and as it is just a string we do it like before
 *         00 00 00 06 = 6 (string length)
 *        72 101 108 108 111 33 = Hello!
 * 
 * Ok, let's start!
