fsockopen
以socket方式打开一个连接
我最常用的是模拟post
这个是小李挖掘的到的...不错
至于要模拟get方式....直接file_get_content就行了.
代码见后面
stream_socket_client, 代码见后面
这个和fsockopenfsockopen一样.以socket方式打开一个连接,只是参数不同
stream_socket_server
建立一个socket server端, 代码见后面
如果是建立的是tcp的server 就用stream_socket_accept进行通讯
如果是建立的是udp的server 就用stream_socket_recvfrom和stream_socket_sendto进行通讯,而且stream_socket_server中需要加个参数STREAM_SERVER_BIND
还有个socket扩展,这个是最基础的建立socket,但是从
这里就不介绍了.
