Возвращаемое значение

An array describing the status of the site regarding available updates. If there is no update data, only one record will be returned, indicating that the status of core can't be determined. If data is available, there will be two records: one for core, and another for all of contrib (assuming there are any contributed modules or themes enabled on the site). In addition to the fields expected by hook_requirements ('value', 'severity', and optionally 'description'), this array will contain a 'reason' attribute, which is an integer constant to indicate why the given status is being returned (UPDATE_NOT_SECURE, UPDATE_NOT_CURRENT, or UPDATE_UNKNOWN). This is used for generating the appropriate e-mail notification messages during update_cron(), and might be useful for other modules that invoke update_requirements() to find out if the site is up to date or not.
