  <para>
   <function>msg_set_queue</function> allows you to change the values of the
   msg_perm.uid, msg_perm.gid, msg_perm.mode and msg_qbytes fields of the
   underlying message queue data structure.
  </para>
  <para>
   Changing the data structure will require that PHP be running as the same
   user that created the queue, owns the queue (as determined by the
   existing msg_perm.xxx fields), or be running with root privileges.
   root privileges are required to raise the msg_qbytes values above the
   system defined limit.
