What is the potential issue with including a PHP file in an HTML file and accessing a class defined in the included file?
The potential issue with including a PHP file in an HTML file and accessing a class defined in the included file is that the PHP code will not be executed unless the file is processed by a PHP interpreter. To solve this issue, you can rename the HTML file to have a .php extension so that the server recognizes it as a PHP file and processes the PHP code within it.
<?php
include 'included_file.php';
$object = new ClassName();
$object->someMethod();
?>
