- $post =1;
- $url = parse_url($url);
- $host ='http://www.phpfensi.com';
- $path ='/';
- $query ='?action=phpfensi.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);

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.phpfensi.com", 80, $errno, $errstr, 30);
- if (!$fp) {
- echo "$errstr ($errno)
";- } else {
- $out = "get / http/1.1 ";
- $out .= "host: www.phpfensi.com";
- $out .= "connection: close ";
- fwrite($fp, $out);
- while (!feof($fp)) {
- echo fgets($fp, 128);
- }
- fclose($fp);
- }
