复制代码 代码如下:

<?php
$host = www.sohu.com; //这个地址随便，用新浪的也行，主要是测试用，哪个无所谓
$page = \"/index.html\";
$port = 80;
$request = \"GET $page HTTP/1.1\\r\\n\";
$request .= \"Host: $host\\r\\n\";
//$request .= \"Referer:$host\\r\\n\";
$request .= \"Connection: close\\r\\n\\r\\n\";
//允许连接的超时时间为1.5秒
$connectionTimeout = 1.5;
//允许远程服务器2秒钟内完成回应
$responseTimeout = 2;
//建立一个socket连接
$fp = fsockopen($host, $port, $errno, $errstr, $connectionTimeout);
if (!$fp) {
    throw new Exception(\"Connection to $hostfailed:$errstr\");
} else {
    stream_set_blocking($fp, true);
    stream_set_timeout($fp, $responseTimeout);
}
//发送请求字符串
fwrite($fp, $request);
//取得返回的数据流内容
$content = stream_get_contents($fp);
echo $content;
$meta = stream_get_meta_data($fp);
if ($meta[\'timed_out\']) {
    throw new Exception(\"Responsefrom web services server timed out.\");
}
//关闭Socket连接
fclose($fp);
