What are best practices for ensuring that PHP functions are properly executed when called by CronJobs, especially in cases where certain variables may not be set as expected?

When running PHP functions via CronJobs, it's important to ensure that all necessary variables are properly set to avoid unexpected errors. One way to handle this is by explicitly setting any required variables within the PHP script being called by the CronJob. This can be done by checking if the variables are set and assigning default values if needed before executing the functions. 

<?php
// Ensure required variables are set before executing functions
$variable1 = isset($variable1) ? $variable1 : 'default_value';
$variable2 = isset($variable2) ? $variable2 : 'default_value';

// Call the function with the required variables
your_function($variable1, $variable2);

// Define your_function here
function your_function($var1, $var2) {
    // Function logic goes here
}
?>
