protected ApcuBackend::getAll($prefix = '')
Returns all cached items, optionally limited by a cache ID prefix.
APCu is a memory cache, shared across all server processes. To prevent cache item clashes with other applications/installations, every cache item is prefixed with a unique string for this site. Therefore, functions like apcu_clear_cache() cannot be used, and instead, a list of all cache items belonging to this application need to be retrieved through this method instead.
Parameters
string $prefix: (optional) A cache ID prefix to limit the result to.
Return value
\APCUIterator An APCUIterator containing matched items.
