php用fsockopen来GET网页 就是不成功 觉得是fread那里有问题 求大神解答

  • 文件写入
  • socket编程 ping命令
  • php

<?php
class Http {

const CRLF = " ";

protected $fp = null;
protected $errno = -1;
protected $errstr = 'error';
protected $fenxi = array();
protected $method = '';
protected $out = '';
//我觉得不需要下面两个
protected $lineone = array();
protected $linetwo = array();

public function __construct($url) {
$this->conn($url);
//$this->same($this->method);
}

public function __destruct() {
$this->close();
}

public function conn($url) {
$this->fenxi = parse_url($url);
if (empty($this->fenxi['port'])) {
$this->fenxi['port'] = 80;
}

$this->fp = fsockopen($this->fenxi['host'], $this->fenxi['port'], $this->errno, $this->errstr, 3);
if (!$this->fp) {
echo $this->errstr;
}

}

public function same($method) {
$this->lineone[0] = $method . ' ' . $this->fenxi['path'] . ' ' . 'HTTP/1.1';
$this->linetwo[0] = 'Host:' . ' ' . $this->fenxi['host'];
$arr = array_merge($this->lineone, $this->linetwo);
$string = implode(self::CRLF, $arr);

if ($method == 'GET') {
$this->get($string);
} elseif ($method == 'POST') {
$this->post($string);
} else {
echo "method error";
exit;
}
}

public function get($str) {
//如果还要写别的东西 写在下面拼接

//这里直接处理$str
fwrite($this->fp, $str);

while (!feof($this->fp)) {
$this->out .= fread($this->fp, 1024);
echo "ok";exit;
}

$this->show();

}

public function post($str) {

}

public function close() {
fclose($this->fp);
}

public function show() {
echo $this->out;
}

}

$test = new Http('http://news.163.com/13/0613/09/9187CJ4C00014JB6.html');
$test->same('GET');

?>
