How can I properly retrieve and store the values from an HTML form select input in a PHP variable?

To properly retrieve and store the values from an HTML form select input in a PHP variable, you can use the $_POST superglobal array to access the selected value. You need to ensure that the select input in your HTML form has a name attribute so that it can be identified when the form is submitted. Once the form is submitted, you can use $_POST['select_name'] to retrieve the selected value and store it in a PHP variable. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $selected_value = $_POST['select_name'];
    // Use $selected_value for further processing
}
?>

<form method="post">
    <select name="select_name">
        <option value="value1">Option 1</option>
        <option value="value2">Option 2</option>
        <option value="value3">Option 3</option>
    </select>
    <input type="submit" value="Submit">
</form>
