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