What are some best practices for assigning values to variables based on PHP configuration settings?

When assigning values to variables based on PHP configuration settings, it is important to first check if the configuration setting exists using the `ini_get()` function. This ensures that the code is robust and does not rely on assumptions about the PHP configuration. Once the configuration setting is confirmed to exist, the value can be assigned to a variable for further use. 

// Check if the configuration setting 'max_execution_time' exists
if (ini_get('max_execution_time')) {
    $maxExecutionTime = ini_get('max_execution_time');
} else {
    $maxExecutionTime = 30; // Default value if configuration setting doesn't exist
}
