˵��

msg_get_queue ( int $key [, int $perms = 0666 ] ) : resource

msg_get_queue() returns an id that can be used to access the System V message queue with the given key. The first call creates the message queue with the optional perms. A second call to msg_get_queue() for the same key will return a different message queue identifier, but both identifiers access the same underlying message queue.

perms

Queue permissions. Default to 0666. If the message queue already exists, the perms will be ignored.
