Laravel 5: forget cache not working

Question

I try to delete specific cached data using:

Cache::forget('key');

also tried

Cache::pull('key');

but cache still existed in DB

note: I'm using Database cache, and Laravel 5.1.7

Answer 1

I found the answer, the problem happen because I copy cache key from DB with prefix, and Laravel normally add another prefix, and it will never matched

Answer 2

For the records: if you are using cache tags, the forget method will not work. This is what I managed to do to solve the problem:

    $cache_key = "MY_CACHE_KEY";
    $cache_tags = ["MY_CACHE_TAG"]; //SOMETIMES I USE MULTIPLE TAGS
    if (\Cache::tags($cache_tags)->has($cache_key)) {
        \Cache::tags($cache_tags)->forget($cache_key);
        $results = "CACHE item " . $cache_key . " forgotten";
    } else {
        $results = "Key " . $cache_key . " IS NOT CACHED";
    }
