msg_get_queue
( int $key
[, int $permissions = 0666

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 permissions.
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.

permissions- Queue permissions. Default to 0666. If the message queue already exists, the
permissionswill be ignored.
返回值
Returns SysvMessageQueue instance that can be used to access the System V message queue,
