教程集为您提供PHP socket,server,cient,模拟post等资源，欢迎您收藏本站，我们将为您提供最新的PHP socket,server,cient,模拟post资源

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

<o:p> </o:p>

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

<o:p> </o:p>

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

<o:p> </o:p>

还有个socket扩展,这个是最基础的建立socket,但是从<st1:chsdate isrocdate="False" islunardate="False" day="30" month="12" year="1899" w:st="on">5.3.0</st1:chsdate>开始就放到pecl中了.

这里就不介绍了.
