本文展示了一个使用 PHP 的 Socket 编程实现的简单服务器端示例，该服务器能够监听指定 IP 地址及端口上的连接请求，并与客户端进行交互。通过此示例可以了解如何创建 Socket、绑定地址、监听连接以及读写数据。

After the socket socket has been created using socket_create() and bound to a name with socket_bind(),
it may be told to listen for incoming connections on socket.

/*
this function will accept incoming connections on that socket.
Once a successful connection is made, a new socket resource is returned, which may be used for communication.
If there are multiple connections queued on the socket, the first will be used.
If there are no pending connections, socket_accept() will block until a connection becomes present.
If socket has been made non-blocking using socket_set_blocking() or socket_set_nonblock(), FALSE will be returned.

 The function socket_read() reads from the socket resource socket created by the socket_create() or socket_accept() functions.
