How can the EVA principle be applied to improve code quality in PHP projects?

Issue: The EVA principle (Error, Validation, and Exception handling) can be applied to improve code quality in PHP projects by ensuring that errors are properly handled, input data is validated, and exceptions are caught and handled gracefully. Code snippet: 

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