Is it considered a best practice to use a submit button for capturing selectbox values in PHP?

When capturing selectbox values in PHP, it is considered a best practice to use a submit button within a form to ensure that the selected value is properly submitted to the server. This allows for the data to be processed and handled accordingly. Without a submit button, the selected value may not be captured and processed as intended. 

<form method="post" action="process.php">
    <select name="selectbox">
        <option value="option1">Option 1</option>
        <option value="option2">Option 2</option>
        <option value="option3">Option 3</option>
    </select>
    <input type="submit" name="submit" value="Submit">
</form>
