How can incomplete HTML tags in PHP code affect the functionality of a web application in different browsers?

Incomplete HTML tags in PHP code can affect the functionality of a web application in different browsers by causing rendering issues, layout problems, and potentially breaking the functionality of the page. To solve this issue, it is important to ensure that all HTML tags are properly closed and nested correctly in the PHP code. 

<?php
echo "<html>";
echo "<head>";
echo "<title>My Page</title>";
echo "</head>";
echo "<body>";
echo "<h1>Hello World</h1>";
echo "</body>";
echo "</html>";
?>
