How can PHP developers ensure that their code is properly executed and not displayed as plain text in the browser?

When PHP code is displayed as plain text in the browser, it usually means that the PHP interpreter is not properly configured on the server. To ensure that PHP code is executed correctly, developers should make sure that their files have a .php extension, that the server supports PHP, and that the files are being accessed through a web server. 

<?php
// Ensure that PHP code is executed and not displayed as plain text
echo "Hello, World!";
?>
