    imap_get_quota

    (PHP 4 >= 4.0.5, PHP 5, PHP 7, PHP 8)

    imap_get_quota — Retrieve the quota level settings, and usage statics per mailbox

    Description

    imap_get_quota(IMAP\Connection $imap, string $quota_root): array|false

    Retrieve the quota level settings, and usage statics per mailbox.

    For a non-admin user version of this function, please see the imap_get_quotaroot() function of PHP.

    Parameters

    imap

    An IMAP\Connection instance.

    quota_root

    quota_root should normally be in the form of user.name where name is the mailbox you wish to retrieve information about.

    Return Values

    Returns an array with integer values limit and usage for the given mailbox. The value of limit represents the total amount of space allowed for this mailbox. The usage value represents the mailboxes current level of capacity. Will return false in the case of failure.

    As of PHP 4.3, the function more properly reflects the functionality as dictated by the » RFC2087. The array return value has changed to support an unlimited number of returned resources (i.e. messages, or sub-folders) with each named resource receiving an individual array key. Each key value then contains an another array with the usage and limit values within it.

    For backwards compatibility reasons, the original access methods are still available for use, although it is suggested to update.

    Changelog

    Version Description
    8.1.0 The imap parameter expects an IMAP\Connection instance now; previously, a valid imap resource was expected.

    If you're using this (or probably any other imap functions) and getting "Notice: Unknown: Quota root does not exist (errflg=2) in Unknown on line 0" errors after the script finishes, then call imap_errors() function before you close the imap stream - this will clear the error stack and you don't get those annoying notices.

    Took me a while to figure it out.

    For this function to work your IMAP server must also have the 'getquota' capability!

    Check this by logging in directly:
    telnet <mail server> <port>

    e.g. telnet mail.myserver.com 143

    and then once you're connected to the server

    ok, this error just occurs if there are no quotas on your mailbox.

    same with imap_get_quotaroot().
