$post =1;

$url = parse_url($url);

$host ='http://www.最模板zuimoban.com';

$path ='/';

$query ='?action=最模板zuimoban.com';

$port =80;

if($post) {

$out = "post $path http/1.0 ";

$out .= "accept: */* ";

//$out .= "referer: $boardurl ";

$out .= "accept-language: zh-cn ";

$out .= "content-type: application/x-www-form-urlencoded ";

$out .= "user-agent: $_server[http_user_agent] ";

$out .= "host: $host ";

$out .= 'content-length: '.strlen($post)." ";

$out .= "connection: close ";

$out .= "cache-control: no-cache ";

$out .= "cookie: $cookie ";

$out .= $post;

} else {

$out = "get $path http/1.0 ";

$out .= "accept: */* ";

//$out .= "referer: $boardurl ";

$out .= "accept-language: zh-cn ";

$out .= "user-agent: $_server[http_user_agent] ";

$out .= "host: $host ";

$out .= "connection: close ";

$out .= "cookie: $cookie ";

}

$fp = @fsockopen(($ip ? $ip : $host), $port, $errno, $errstr, $timeout);

if(!$fp)

{

return '';//note $errstr : $errno

} else {

return '成功访问';

}

fsockopen语法:resource fsockopen(string $hostname [,int $port = -1 [, int &$errno [,string &$errstr [, float $timeout = ini_get("default_socket_timeout") ]]]] )

启动一个套接字连接到指定的主机的资源,php支持在互联网领域的目标和unix在所支持的套接字传输列表说明,所支持的传输列表也可以检索使用stream_get_transports（）.

该插座预设会被启用,阻塞模式,你可以切换到非阻塞模式使用stream_set_blocking（）,如果上面实例看不懂,就来看个简的吧,代码如下:

$fp = fsockopen("www.最模板zuimoban.com", 80, $errno, $errstr, 30);

if (!$fp) {

echo "$errstr ($errno) ";

} else {

$out = "get / http/1.1 ";

$out .= "host: www.最模板zuimoban.com";

$out .= "connection: close ";

fwrite($fp, $out);

while (!feof($fp)) {

echo fgets($fp, 128);

}

fclose($fp);

}
