What are the potential pitfalls of using numerical indices in $_POST arrays in PHP?

When using numerical indices in $_POST arrays in PHP, a potential pitfall is that it can be difficult to manage and access the data, especially if the indices are not consistent. To solve this issue, you can use associative arrays instead of numerical indices. By using descriptive keys, you can easily access and manipulate the data in a more organized manner. 

// Using associative arrays in $_POST
$data = array(
    'name' => $_POST['name'],
    'email' => $_POST['email'],
    'age' => $_POST['age']
);
