What are some best practices for integrating PHP and HTML to ensure proper functionality of form elements like checkboxes?

When integrating PHP and HTML to handle form elements like checkboxes, it is important to ensure that the checkboxes are properly checked or unchecked based on the data received from the server. One common issue is not setting the 'checked' attribute for checkboxes that should be pre-selected. To solve this, you can use PHP to check if the checkbox value matches the data from the server and add the 'checked' attribute accordingly. 

<?php
// Assume $data contains the values received from the server
$checkboxValue = $data['checkbox_value'];

?>

<input type="checkbox" name="checkbox" value="1" <?php echo ($checkboxValue == '1') ? 'checked' : ''; ?>>
<label for="checkbox">Checkbox Label</label>
