How can the EVA principle be applied to improve error handling and data processing in PHP scripts?

Issue: The EVA principle (Error Visibility and Avoidance) can be applied to improve error handling and data processing in PHP scripts by ensuring that errors are caught and handled appropriately to prevent them from causing issues in the application.

php 
try {
    // Code that may throw an exception
    $result = some_function_that_may_throw_an_exception();
    
    // Process the result
    echo $result;
} catch (Exception $e) {
    // Handle the exception
    echo 'An error occurred: ' . $e->getMessage();
}
