Accessing google drive by running cron job - php

Question

Here I am using google drive to backup my data on drive and for that I wrote a script which i want to run through cronjob. but it needs access_token to access google drive. I am keeping access token in my db and providing it to backup file but that token is not getting updated through cronjob . but when I am running it on browser then working fine. I want to update token through cronjob which didn't get updated.
