使用php模拟http请求

// Returns array with headers in $response[0] and body in $response[1]function http_post($request, $host, $path, $port = 80, $ip=null) {$http_request  = "POST $path HTTP/1.0\r\n";$http_request .= "Host: $host\r\n";$http_request .= 'Content-Type: application/x-www-form-urlencoded; charset=' . get_option('blog_charset') . "\r\n";$http_request .= "Content-Length: {$content_length}\r\n";$http_request .= "User-Agent: {$akismet_ua}\r\n";$http_request .= "\r\n";$http_request .= $request;$response = '';if( false != ( $fs = @fsockopen( $http_host, $port, $errno, $errstr, 10 ) ) ) {fwrite( $fs, $http_request );while ( !feof( $fs ) )$response .= fgets( $fs, 1160 ); // One TCP-IP packetfclose( $fs );$response = explode( "\r\n\r\n", $response, 2 );}return $response;}
