How can naming conventions for form elements in PHP scripts impact functionality?

Naming conventions for form elements in PHP scripts can impact functionality by affecting how the data is processed and accessed. It is important to use consistent and descriptive names for form elements to ensure that the data is properly handled and can be easily identified. This can help prevent errors and make the code more readable and maintainable.

// Example of using consistent and descriptive naming conventions for form elements
<form action="process_form.php" method="post">
    <input type="text" name="username" placeholder="Username">
    <input type="password" name="password" placeholder="Password">
    <button type="submit">Submit</button>
</form>
