# socket_accept

(PHP 4 >= 4.1.0)

socket_accept -- Accepts a connection on a socket

## Description

``int socket_accept` (resource socket)`

Warning
This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change in a future release of PHP without notice. Be warned and use this function at your own risk.

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 descriptor 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(), an error code will be returned.

The socket descriptor returned by socket_accept() may not be used to accept new connections. The original listening socket `socket`, however, remains open and may be reused.

Returns a new socket descriptor on success, or a negative error code on failure. This code may be passed to socket_strerror() to get a textual explanation of the error.

See also socket_bind(), socket_connect(), socket_listen(), socket_create(), socket_get_status(), and socket_strerror().
