stream_socket_accept()

(PHP 5, PHP 7)

接受由stream_socket_server()创建的套接字连接

说明

接受由stream_socket_server()创建的套接字连接。

参数

需要接受的服务器创建的套接字连接。

覆盖默认的套接字接受的超时时限。输入的时间需以秒为单位。

如果包含该参数并且是可以从选中的传输数据中获取到，则将被设置给连接中的客户端主机的名称（地址）（怕出入很大，附带上原文：Will be set to the name (address) of the client which connected, if included and available from the selected transport.）

也可以之后通过stream_socket_get_name()来确定。

返回值

返回接受套接之后的资源流或者在失败时返回FALSE。

注释

该函数不能被用于 UDP 套接字。可以使用stream_socket_recvfrom()和stream_socket_sendto()来取而代之。

This code could be very helpfull...
The following code is for the "server". It listen for a message until CTRL-C

The following code is for the "client". It send a message, and read the respons... 

To check if there's a new connection waiting, without blocking, or (when using non-blocking mode) without notices), you can use stream_accept (as opposed to socket_select). 

this function, compared to the function socket_accept, got an extra argument "timeout".
To make this function wait indefinitelly to incoming connections, just as in socket_accept, set timeout to -1. It works for me with PHP 5.0.4.

Note that if you use 0 as timeout, the connection will timeout right away.

To whom it may concern, and it may concern you greatly, stream_set_blocking has no effect on stream_socket_accept.
If you want it to return right away, connection or not, use 0 for the timeout parameter.
