What are some common methods for storing user selections in PHP applications?

One common method for storing user selections in PHP applications is to use session variables. By storing user selections in session variables, you can maintain the selected options across multiple pages and sessions. Another method is to store user selections in cookies, which can be useful for remembering user preferences even after they have closed the browser. Additionally, you can store user selections in a database if you need to persist the data for future use. 

// Storing user selection in a session variable
session_start();
$_SESSION['user_selection'] = 'Option A';
```

```php
// Storing user selection in a cookie
setcookie('user_selection', 'Option B', time() + 3600, '/');
```

```php
// Storing user selection in a database
$selectedOption = 'Option C';
// Store $selectedOption in the database using appropriate SQL query
