PHP code is written inside <?php ... ?> tags. The PHP interpreter processes this code on the server, and the output is sent as HTML to the browser.
<?php
echo "Hello, World!";
?>
🔹 Explanation:
<?php → Starts the PHP script.echo → Outputs text to the browser."Hello, World!" → Text inside quotes is displayed.?> → Ends the PHP script (optional if the file contains only PHP code).
PHP can be embedded inside an HTML document.
<!DOCTYPE html>
<html>
<head>
<title>PHP Example</title>
</head>
<body>
<h1>Welcome to My Website</h1>
<p>Today’s date is: <?php echo date("Y-m-d"); ?></p>
</body>
</html>

Each PHP statement must end with a semicolon (;).
