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
(default: 0666). 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. If the
message queue already exists, the
perms
will be ignored.

msg_remove_queue()
,
msg_receive()
,
msg_send()
,
msg_stat_queue()
and
msg_set_queue()
.
This function was introduced in PHP 4.3.0 (not yet
