I used put function for make new manual Cashe. for example :
$cashtime =Cache::put('filekey', 'mycashtime', 20);
and sent it to view but it not expired . when i send it to view it will back me true. but after 20s have to send me false and expire it.
and then how can i check it is expired or not .
I solved it.my problem was first I have to check if key doesnt exist set again else do someting.
