(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.
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.
