socket_create_listen

(PHP 4 >= 4.1.0)

socket_create_listen -- Opens a socket on port to accept connections

Description

resource socket_create_listen ( int port [, int backlog])

Warning

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

This function is meant to ease the task of creating a new socket which only listens to accept new connections.

socket_create_listen() create a new socket resource of type AF_INET listening on all local interfaces on the given port waiting for new connections.

The backlog parameter defines the maximum length the queue of pending connections may grow to. SOMAXCONN may be passed as backlog parameter, see socket_listen() for more information.

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.

Note: If you want to create a socket which only listens on a certain interfaces you need to use socket_create(), socket_bind() and socket_listen().

See also socket_create(), socket_bind(), socket_listen(), socket_last_error() and socket_strerror().
