How can PHP variables be effectively used to control the number of users displayed per page in a user list?

To control the number of users displayed per page in a user list using PHP variables, you can use a combination of HTML form inputs and PHP logic. Create a form with a dropdown menu or input field where the user can select the number of users to display per page. Then, use PHP to retrieve the selected value from the form and use it to limit the number of users displayed in the user list query. 

<?php
// Get the selected number of users per page from the form
$usersPerPage = isset($_POST['usersPerPage']) ? $_POST['usersPerPage'] : 10;

// Query to retrieve users from the database with LIMIT based on the selected number of users per page
$query = "SELECT * FROM users LIMIT $usersPerPage";

// Execute the query and display the users in the user list
// Your code to execute the query and display the users goes here
?>
```

In your HTML form, you can include a dropdown menu like this:

```html
<form method="post">
    <label for="usersPerPage">Users Per Page:</label>
    <select name="usersPerPage" id="usersPerPage">
        <option value="10">10</option>
        <option value="20">20</option>
        <option value="50">50</option>
    </select>
    <input type="submit" value="Update">
</form>
