fsockopen語法:

復制代碼代碼如下:

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

啟動一個套接字連接到指定的主機的資源,php支持在互聯(lián)網(wǎng)領域的目標和unix在所支持的套接字傳輸列表說明,所支持的傳輸列表也可以檢索使用stream_get_transports（）.

該插座預設會被啟用,阻塞模式,你可以切換到非阻塞模式使用stream_set_blocking（）,如果上面實例看不懂,就來看個簡的吧,代碼如下:

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