In what situations would PHP output HTML instead of executing PHP code, leading to errors?

When PHP outputs HTML instead of executing PHP code, it typically occurs when the PHP opening tag "<?php" is missing or not properly formatted. To solve this issue, make sure that all PHP code is enclosed within the PHP opening and closing tags. Additionally, ensure that the file extension is ".php" and that the server is configured to interpret PHP code. 

&lt;?php
// Correct way to output PHP code
echo &quot;Hello, World!&quot;;
