How can PHP variables from dropdown menus be properly passed and processed in a contact form?

When using dropdown menus in a contact form, the selected option needs to be properly passed to the PHP script for processing. This can be achieved by assigning the selected option to a variable in the PHP script using the $_POST superglobal array. The selected option can then be accessed and processed as needed. 

// HTML form with dropdown menu
<form method="post" action="process_form.php">
    <select name="dropdown_menu">
        <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>

// process_form.php
<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $selected_option = $_POST['dropdown_menu']; // Get the selected option from the dropdown menu

    // Process the selected option
    if ($selected_option == 'option1') {
        // Process for option 1
    } elseif ($selected_option == 'option2') {
        // Process for option 2
    } elseif ($selected_option == 'option3') {
        // Process for option 3
    } else {
        // Handle invalid option
    }
}
?>
