Description
     This function returns an array of all of the IMAP alert messages
     generated since the last imap_alerts() call,
     or the beginning of the page. When
     imap_alerts() is called, the alert stack is
     subsequently cleared. The IMAP specification requires that these
     messages be passed to the user.
