使用fsockopen()函数来实现获取页面信息，完整代码如下
//设置字符集（由于要抓取的网易网站字符集编码是gbk编码）
header("content-type:text/html;charset=gb2312");
//设置中国时区
date_default_timezone_set(\'PRC\');
//页面域名
$hostname = "news.163.com";//"www.163.com";
//请求方式
$method = \'GET\';
//URI资源唯一标识
$target = \'/17/1225/09/D6G89EED000189FH.html\'; // Specific program
//所带参数
$getValues = \'\';// or $getValues = "?key1=value1&key2=value2";
$port = 80;
$fp = fsockopen($hostname, $port=80, $errno, $errstr, 30);
if (!$fp) {
echo "####Failed!$errstr ($errno)<br/>\\n";
} else {
//注意空格
$out = "$method $target$getValues HTTP/1.1\\r\\n"; //原$out = "GET / HTTP/1.1\\r\\n";
//$out .= "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8\\r\\n";
//$out .= "Accept-Encoding: gzip, deflate\\r\\n";
//注意冒号后面要有一个空格
$out .= "Accept-Language: zh-CN,zh;q=0.9\\r\\n";
$out .= "User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.94 Safari/537.36\\r\\n";
$out .= "Host: $hostname\\r\\n";
$out .= "Cache-Control: max-age=0\\r\\n";
$out .= "Connection: Close\\r\\n\\r\\n";
fwrite($fp, $out);
while (!feof($fp)) {
echo fgets($fp, 128);
}
fclose($fp);
}
根据以上示例，可以进行通过设置请求头信息，即可实现任意端口的访问
代码执行后效果
