PHP implementation HttpClient Class example

  This article mainly introduces the PHP implementation HttpClient Class example, the need for friends can refer to the following

  Code as follows: Httpclient::init ($httpClient, $args = null); $httpClient->get ($url, $data = null, $cookie = null); Var_dump ($httpClient->buffer);       Code as follows: <?php   class HttpClient {   public $buffer = null;  //buffer gets the returned string  public $referer = null;  //referer set http_referer URL  public $response = null; Header information for Response server response  public $request = null;  //Request header information sent to the server  private $args = null;    public static function init (& $instanceof, $args = Array ()) {  Return $instanceof = new self ($args); &NBSP}    private function __construct ($args = Array ()) {    if (!is_array ($args)) $args = Array ();   $this->args = $args;   if (!empty ($this->args[' debugging ')) {   ob_end_clean ();    set_time_limit (0);   & Nbsp;header (' Content-type:text/plain; Charset=utf-8 ');  }   &NBSP}    public function get ($urL, $data = null, $cookie = null) {    $parse = Parse_url ($url);   $url. = Isset ($parse [' query '])?
