How can PHP sessions be used to store information from a dropdown menu selection?

To store information from a dropdown menu selection using PHP sessions, you can capture the selected value when the form is submitted and store it in a session variable. This allows you to access the selected value across different pages during the user's session. 

<?php
session_start();

if(isset($_POST['dropdown_selection'])){
    $_SESSION['selected_option'] = $_POST['dropdown_selection'];
}

?>

<form method="post">
    <select name="dropdown_selection">
        <option value="option1">Option 1</option>
        <option value="option2">Option 2</option>
        <option value="option3">Option 3</option>
    </select>
    <input type="submit" value="Submit">
</form>
