这篇文章主要介绍了php实现httpclient类示例,需要的朋友可以参考下

 代码如下: httpClient::init($httpClient, $args = null); $httpClient->get($url, $data = null, $cookie = null); var_dump($httpClient->buffer);      代码如下: <?php   class httpClient {    public $buffer = null;  // buffer 获取返回的字符串  public $referer = null;  // referer 设置 HTTP_REFERER 的网址  public $response = null; // response 服务器响应的 header 信息  public $request = null;  // request 发送到服务器的 header 信息  private $args = null;    public static function init(&$instanceof, $args = array()) {   return $instanceof = new self($args);  }    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);    header('Content-Type: text/plain; charset=utf-8');   }    }    public function get($url, $data = null, $cookie = null) {     $parse = parse_url($url);   $url .= isset($parse['query']) ? '&'. $data : ( $data ? '?'. $data : '' );   $host = $parse['host'];     $header  = 'Host: '. $host. "rn";   $header .= 'Connection: close'. "rn";   $header .= 'Accept: */*'.
