What is the best practice for handling form submissions in PHP to fill a variable with the selected value from a dropdown menu?

When handling form submissions in PHP to fill a variable with the selected value from a dropdown menu, you can use the $_POST superglobal array to retrieve the selected value. Make sure to check if the form has been submitted before accessing the value to avoid errors. You can then assign the selected value to a variable for further processing. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $selectedValue = $_POST["dropdown_menu"];
    
    // Further processing with the selected value
}
?>

<form method="post">
    <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>
