How can PHP developers effectively mark form fields using PHP code?

When working with forms in PHP, it is important to mark required fields to provide users with clear guidance on what information needs to be provided. This can be done by adding an asterisk (*) or any other visual indicator next to the field label. This can be achieved by using PHP code to dynamically add the required indicator based on the form field's validation rules.

<label for="name">Name: <?php if($name_required) echo '<span class="required">*</span>'; ?></label>
<input type="text" id="name" name="name" required>
