How can one ensure that PHP code is compliant with web standards, such as those provided by the W3C validator?

To ensure that PHP code is compliant with web standards, such as those provided by the W3C validator, it is important to write clean and valid HTML output from PHP scripts. This can be achieved by properly structuring the HTML code within the PHP files, using valid HTML tags, attributes, and avoiding inline styles or scripts. Additionally, using PHP functions like htmlspecialchars() to escape special characters can help prevent issues with validation. 

<?php
// Example PHP code snippet generating valid HTML output
echo '<!DOCTYPE html>';
echo '<html>';
echo '<head>';
echo '<title>My Page</title>';
echo '</head>';
echo '<body>';
echo '<h1>Hello World!</h1>';
echo '</body>';
echo '</html>';
?>
