socket_create_listen
Opens a socket on port to accept connections
(PHP 4 >= 4.0.7, PHP 5)
resource socket_create_listen ( int port [, int backlog] )
socket_create_listen() creates a new socket resource of
type AF_INET listening on all
local interfaces on the given port waiting for new connections.
This function is meant to ease the task of creating a new socket which only listens to accept new connections.
Parameters
- port
The port on which to listen on all interfaces.
- backlog
The backlog parameter defines the maximum length the queue of pending connections may grow to.
SOMAXCONNmay be passed as backlog parameter, see socket_listen() for more information.
Return Values
socket_create_listen() returns a new socket resource
on success or FALSE on error. The error code can be retrieved with
socket_last_error(). This code may be passed to
socket_strerror() to get a textual explanation of the
error.
Notes
If you want to create a socket which only listens on a certain interface you need to use socket_create(), socket_bind() and socket_listen().
