How can changing the file extension from .html to .php impact the execution of PHP code within a webpage?
Changing the file extension from .html to .php allows the web server to recognize and execute PHP code within the webpage. This enables the server to interpret and process PHP scripts, allowing for dynamic content generation and interaction with databases. To ensure that PHP code is executed properly, make sure to include the opening and closing PHP tags <?php and ?> around the PHP code snippets.
<?php
// PHP code here
?>
