PHP socket类

没事的时候自己封装了一个socket类

功能很简单和curl功能是一样的

class socketClass{    private $host;    private $url;    private $error_no = 0;    public $error_str = '';    private $port = 80;    private $timeout = 5;    private $method;    private $param;    private $fp;    private $content = '';    private $header = array();    public function __construct($host, $port, $url, $param, $method='GET', $timeout=5) {        $this->host = $host;        $this->port = $port;        $this->url = $url;        $this->timeout = $timeout;        $this->method = $method;        if(is_array($param)){            $this->param = http_build_query($param);        }else{            $this->param = $param;        }    }    private function connect(){        $this->fp = fsockopen($this->host, $this->port, $this->error_no, $this->error_str, $this->timeout);        if(!$this->fp){            $this->error_str = 'socket connect failed';            return false;        }        return true;    }    private function send(){        $this->fp = '';        if(!$this->connect()){            $this->error_str = 'connect socket failed';            return false;        }        if($this->method == 'POST'){            $header = "POST $this->url HTTP/1.1\r\n";        }else{            if(!empty($this->param)){                $header = "GET $this->url?$this->param HTTP/1.1\r\n";            }else{                $header = "GET $this->url HTTP/1.1\r\n";            }        }        $header .= "Content-Length:" . strlen($this->param) .
