How can validating the generated HTML code using tools like the W3C Validator help in identifying and fixing issues with PHP-generated output?
Validating the generated HTML code using tools like the W3C Validator can help in identifying issues such as missing closing tags, improperly nested elements, or invalid attributes. By ensuring that the PHP-generated output complies with HTML standards, it can help in fixing layout inconsistencies, browser compatibility problems, and accessibility issues.
<?php
ob_start();
// PHP code that generates HTML output
$html_output = ob_get_clean();
// Validate the generated HTML code using the W3C Validator
$validator = 'https://validator.w3.org/nu/?doc=' . urlencode($html_output);
header('Location: ' . $validator);
exit();
?>
