Laravel 5：忘记缓存无法正常工作

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

我找到了答案，问题发生的原因是我从带有prefix DB复制cache密钥，而Laravel通常会添加另一个prefix ，并且它永远不会匹配

Answer 2

Try php artisan cache:clear

on command line

Answer 3

If someone needs it, my problem was because of file permissions. So, you can try this command in the root of the project chmod -R 755 . . However, I did chmod -R 777 . , but that's not recommended.

Answer 4

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";
    }
