What are the best practices for naming form inputs in PHP to ensure proper array handling?

When naming form inputs in PHP to ensure proper array handling, it is best practice to use square brackets [] at the end of the input name. This tells PHP to treat the input as an array when the form is submitted. This is particularly useful when dealing with multiple inputs of the same type, such as checkboxes or multiple select options. 

<form method="post">
    <input type="text" name="user[name]">
    <input type="checkbox" name="user[hobbies][]" value="reading">
    <input type="checkbox" name="user[hobbies][]" value="cooking">
    <input type="checkbox" name="user[hobbies][]" value="gardening">
    <input type="submit" value="Submit">
</form>
```

In the PHP code handling the form submission, you can access the input values as an array like this:

```php
$name = $_POST['user']['name'];
$hobbies = $_POST['user']['hobbies'];
