    methodpublicclean(string $mode = \Zend_Cache::CLEANING_MODE_ALL, array $tags = array()) : boolean
    inherited

    Clean some cache records

    Inherited from: \Zend_Cache_Backend_Interface::clean()

    Available modes are : Zend_Cache::CLEANING_MODE_ALL (default) => remove all cache entries ($tags is not used) Zend_Cache::CLEANING_MODE_OLD => remove too old cache entries ($tags is not used) Zend_Cache::CLEANING_MODE_MATCHING_TAG => remove cache entries matching all given tags ($tags can be an array of strings or a single string) Zend_Cache::CLEANING_MODE_NOT_MATCHING_TAG => remove cache entries not {matching one of the given tags} ($tags can be an array of strings or a single string) Zend_Cache::CLEANING_MODE_MATCHING_ANY_TAG => remove cache entries matching any given tags ($tags can be an array of strings or a single string)

    Parameters
    NameTypeDescription
    $modestring

    Clean mode

    $tagsarray

    Array of tags

    Returns
    TypeDescription
    booleantrue if no problem
    methodpublicgetCapabilities() : array

    Return an associative array of capabilities (booleans) of the backend

    The array must include these keys : - automatic_cleaning (is automating cleaning necessary) - tags (are tags supported) - expired_read (is it possible to read expired cache records (for doNotTestCacheValidity option for example)) - priority does the backend deal with priority when saving - infinite_lifetime (is infinite lifetime can work with this backend) - get_list (is it possible to get the list of cache ids and the complete list of tags)

    Returns
    TypeDescription
    arrayassociative of with capabilities
    methodpublicgetFillingPercentage() : int

    Return the filling percentage of the backend storage

    Returns
    TypeDescription
    intinteger between 0 and 100
    methodpublicgetIds() : array

    Return an array of stored cache ids

    TypeDescription
    arrayarray of stored cache ids (string)
    methodpublicgetIdsMatchingAnyTags(array $tags = array()) : array

    Return an array of stored cache ids which match any given tags

    In case of multiple tags, a logical AND is made between tags

    Parameters

    Returns
    TypeDescription
    arrayarray of any matching cache ids (string)
    methodpublicgetIdsMatchingTags(array $tags = array()) : array

    Return an array of stored cache ids which match given tags

    In case of multiple tags, a logical AND is made between tags

    Parameters
    NameTypeDescription
    $tagsarray

    array of tags

    Returns
    TypeDescription
    arrayarray of matching cache ids (string)
    methodpublicgetIdsNotMatchingTags(array $tags = array()) : array

    Return an array of stored cache ids which don't match given tags

    In case of multiple tags, a logical OR is made between tags

    Parameters
    NameTypeDescription
    $tagsarray

    array of tags

    Returns
    TypeDescription
    arrayarray of not matching cache ids (string)
    methodpublicgetMetadatas(string $id) : array

    Return an array of metadatas for the given cache id

    The array must include these keys : - expire : the expire timestamp - tags : a string array of tags - mtime : timestamp of last modification time

    Parameters
    NameTypeDescription

    Return an array of stored tags

    Returns
    TypeDescription
    arrayarray of stored tags (string)
