What are the potential pitfalls of not including the HTML tag in a PHP file?

Not including the HTML tag in a PHP file can lead to unexpected output or errors, as PHP code will be interpreted as plain text by the browser. To solve this issue, it is important to include the HTML tag in PHP files to properly render the output in the browser. 

<?php
// Include the HTML tag in the PHP file
echo "<!DOCTYPE html>";
echo "<html>";
echo "<head>";
echo "<title>PHP HTML Example</title>";
echo "</head>";
echo "<body>";
echo "<h1>Hello, World!</h1>";
echo "</body>";
echo "</html>";
?>
