How can Cronjobs be utilized to handle repetitive tasks in PHP?

Cronjobs can be utilized in PHP to handle repetitive tasks by scheduling scripts to run at specified intervals. This allows for automation of tasks such as sending email reminders, updating database records, or generating reports without manual intervention.

```php
// Example of a PHP script to be executed via a cronjob
<?php
// Perform the repetitive task here
echo "Task executed successfully\n";
?>
```

To schedule this script to run at specific intervals, you can set up a cronjob using the following command:
```
* * * * * php /path/to/your/script.php
```

This cronjob will execute the PHP script every minute. You can adjust the timing by modifying the cronjob schedule accordingly.
