socket_accept
(PHP 4 >= 4.1.0, PHP 5, PHP 7, PHP 8)
socket_accept — Accepts a connection on a socket
Description
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 instance 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 instance returned by
socket_accept() may not be used to accept new
connections. The original listening socket
socket, however, remains open and may be
reused.
Return Values
Returns a new Socket instance 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.
