What are the implications of not specifying a DOCTYPE in a PHP-generated webpage, and how does it affect browser rendering?

Not specifying a DOCTYPE in a PHP-generated webpage can lead to browser rendering issues, as the browser may not know how to interpret the HTML content correctly. To solve this issue, you should include a proper DOCTYPE declaration at the beginning of your PHP-generated webpage to ensure consistent rendering across different browsers. 

<?php
header("Content-Type: text/html; charset=UTF-8");
echo "<!DOCTYPE html>";
echo "<html>";
echo "<head>";
echo "<title>Your Page Title</title>";
echo "</head>";
echo "<body>";
// Your PHP-generated content here
echo "</body>";
echo "</html>";
?>
