# socket_accept

(PHP 4 >= 4.1.0, PHP 5, PHP 7)

socket_accept — Accepts a connection on a socket

### 说明

socket_accept ( resource `$socket` ) : resource

After the socket `socket` has been created using socket_create(), bound to a name with socket_bind(), and told to listen for connections with socket_listen(), 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 socket resource returned by socket_accept() may not be used to accept new connections. The original listening socket `socket`, however, remains open and may be reused.

### 参数

`socket`

  A valid socket resource created with socket_create().

### 返回值

Returns a new socket resource on success, or `FALSE` on error. The actual error code can be retrieved by calling socket_last_error(). This error code may be passed to socket_strerror() to get a textual explanation of the error.
