What are some common methods for handling cronjobs in PHP applications?

One common method for handling cronjobs in PHP applications is to create a separate PHP script that contains the task to be executed, and then set up a cron job on the server to run this script at specified intervals. This ensures that the task is automatically executed without manual intervention.

```php
// cronjob.php
<?php
// Your task code here
echo "Cron job executed successfully!";
?>
```

To set up a cron job on the server, you can use the following command:
```
* * * * * /usr/bin/php /path/to/cronjob.php
```

This cron job will run the `cronjob.php` script every minute. You can adjust the timing as needed by modifying the cron job schedule.
