How can PHP developers prevent errors when including PHP files within a specific tab on a webpage?

To prevent errors when including PHP files within a specific tab on a webpage, PHP developers can use output buffering to capture the output of the included file and then only display it within the specific tab area. This ensures that any errors or output from the included file are contained within the tab and do not affect the rest of the webpage.

<?php
ob_start();
include 'file_to_include.php';
$tab_content = ob_get_clean();
?>
<div class="tab">
    <?php echo $tab_content; ?>
</div>
