How can PHP code be structured to handle form submissions and process the selected values effectively?

To handle form submissions and process selected values effectively in PHP, you can use conditional statements to check if the form has been submitted and process the selected values accordingly. You can access the form data using the $_POST superglobal and perform any necessary validation or processing before displaying the results. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data
    $selectedValue = $_POST['selected_value'];
    
    // Perform any necessary validation or processing
    
    // Display the results
    echo "Selected value: " . $selectedValue;
}
?>

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    <select name="selected_value">
        <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>
