What are potential issues when dealing with multiple code tags in PHP?

One potential issue when dealing with multiple code tags in PHP is that the code can become difficult to read and maintain. To solve this, you can use PHP's heredoc syntax to easily handle large blocks of code without the need for escaping characters or mixing HTML and PHP.

<?php

// Example of using heredoc syntax to handle multiple code tags
echo <<<HTML
<div>
    <h1>Welcome to my website</h1>
    <?php
        $name = "John";
        echo "Hello, $name!";
    ?>
</div>
HTML;

?>
