PHP中fsockopen函数的用法？

\n";} else { $out = "GET / HTTP/1.1\r\n"; $out .= "Host: www.example.com\r\n"; $out .= "Connection: Close\r\n\r\n"; fwrite($fp, $out); while (!feof($fp)) { echo fgets($fp, 128); } fclose($fp);}?>

使用UDP连接

\n";} else { fwrite($fp, "\n"); echo fread($fp, 26); fclose($fp);}?>

使用示例

"somevalue");//build the post string foreach($formdata AS $key => $val){ $poststring .= urlencode($key) . "=" . urlencode($val) . "&"; }// strip off trailing ampersand$poststring = substr($poststring, 0, -1);$fp = fsockopen("ssl://".$host, $port, $errno, $errstr, $timeout = 30);if(!$fp){//error tell usecho "$errstr ($errno)\n"; }else{ //send the server request fputs($fp, "POST $path HTTP/1.1\r\n"); fputs($fp, "Host: $host\r\n"); fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n"); fputs($fp, "Content-length: ".strlen($poststring)."\r\n"); fputs($fp, "Connection: close\r\n\r\n"); fputs($fp, $poststring . "\r\n\r\n"); //loop through the response from the server while(!feof($fp)) { echo fgets($fp, 4096); } //close fp - we are done with it fclose($fp);}
