How can PHP tags be used to improve the code readability and functionality?

Using PHP tags properly can improve code readability and functionality by clearly indicating where PHP code begins and ends within an HTML document. This can help developers easily distinguish between PHP and HTML code, making the code easier to read and maintain. Additionally, using PHP tags correctly can prevent syntax errors and ensure that the PHP code executes as intended.

<!DOCTYPE html>

</head>
<body>
    <h1>Welcome to our website!</h1>
    
    <?php
        // PHP code to display current date
        $currentDate = date("Y-m-d");
        echo "<p>Today's date is: $currentDate</p>";
    ?>
</body>
