php教程 fsockopen函数发送post,get请求获得网页内容(反防采集)

/*
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
