When a user needs a web page that covers PHP code, the code is processed by the PHP module installed on that web server. The PHP pre-processor then generates HTML output to be displayed on the user’s browser screen.

<?php  
 echo “Hello, World!”;
?>

<!DOCTYPE html>
<html >
<?php
language_attributes(); ?>>
<head>
<meta charset=”<?php bloginfo( ‘charset’ ); ?>” />
<title><?php bloginfo( ‘name’ ); ?></title>
</head>
