PHP Interview Questions
What is cron jobs in PHP?
The App Engine Cron Service allows you to configure regularly scheduled tasks that operate at defined times or regular intervals. These tasks are commonly known as cron jobs. These cron jobs are automatically triggered by the App Engine Cron Service. For instance, you might use a cron job to send out an email report on a daily basis, or to update some cached data every 10 minutes, or refresh summary information once an hour.
A cron job makes an HTTP GET request to a URL as scheduled. The handler for that URL executes the logic when it is called. A cron job request is subject to the same limits as those for push task queues.
