# socket_create_listen

(PHP 4 >= 4.1.0, PHP 5)

socket_create_listen -- Opens a socket on port to accept connections

## Description

resource socket_create_listen ( int port [, int backlog] )

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

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.

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.

> Huomaa: 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().

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