What are the potential pitfalls of using multidimensional arrays in PHP form submissions?

Using multidimensional arrays in PHP form submissions can make processing the data more complex and error-prone. It can lead to confusion when trying to access specific values or iterate through the data. To avoid these pitfalls, consider using a more structured approach such as naming the form fields with a consistent naming convention. 

// Example of using consistent naming convention for form fields
<input type="text" name="user[name]">
<input type="email" name="user[email]">
<input type="text" name="user[address]">

// Accessing the form data in PHP
$user = $_POST['user'];
$name = $user['name'];
$email = $user['email'];
$address = $user['address'];
