What is the difference between naming input fields in PHP and Coldfusion?

When naming input fields in PHP, the name attribute should be within square brackets if you want to access the input values as an array in the PHP script. In Coldfusion, input fields are named using the dot notation to access the values as a structure in the Coldfusion code. PHP code snippet:

```php
<input type="text" name="user[name]" />
<input type="text" name="user[email]" />
```

In this PHP code snippet, the input fields are named 'user[name]' and 'user[email]', allowing you to access the input values as an array in the PHP script.
