What resources and documentation can help in understanding and implementing PHP arrays and string manipulation for form data processing?

When working with form data in PHP, understanding how to manipulate arrays and strings is essential for processing the data effectively. The PHP documentation on arrays (https://www.php.net/manual/en/language.types.array.php) and strings (https://www.php.net/manual/en/language.types.string.php) provide detailed explanations and examples on how to work with these data types. Additionally, websites like W3Schools (https://www.w3schools.com/php/) offer tutorials and resources on PHP array and string manipulation. 

// Example code snippet for processing form data using arrays and string manipulation in PHP

// Assuming form data is submitted via POST method
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Accessing form data
    $username = $_POST["username"];
    $email = $_POST["email"];
    
    // Manipulating strings
    $username = ucfirst(strtolower(trim($username))); // Convert to lowercase, trim whitespace, and capitalize first letter
    $email = filter_var($email, FILTER_SANITIZE_EMAIL); // Sanitize email input
    
    // Storing form data in an array
    $formData = array(
        'username' => $username,
        'email' => $email
    );
    
    // Processing form data
    // Perform necessary operations with $formData array
}
