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

The EVA principle in PHP development stands for Error, Validation, and Authentication. By following this principle, developers can ensure that their code is robust, secure, and reliable. To apply the EVA principle in PHP development, developers should thoroughly check for errors, validate user inputs to prevent vulnerabilities, and authenticate users to ensure secure access to resources. 

// Example of applying the EVA principle in PHP development

// Error handling
try {
    // Your PHP code here
} catch (Exception $e) {
    // Handle errors gracefully
    echo "An error occurred: " . $e->getMessage();
}

// Validation
$userInput = $_POST['user_input'];
if (empty($userInput)) {
    // Handle empty input error
    echo "Please enter a valid input";
} else {
    // Proceed with processing the input
}

// Authentication
if ($_SESSION['authenticated'] !== true) {
    // Redirect to login page or deny access
    header("Location: login.php");
    exit;
} else {
    // Proceed with accessing the resource
}
