Why is it not feasible to mix PHP and JavaScript in the context of the provided code?

Mixing PHP and JavaScript directly in the same code can be problematic because PHP is a server-side language that executes on the server before the page is sent to the client, while JavaScript is a client-side language that executes on the client's browser. To overcome this, you can use PHP to generate JavaScript code dynamically within script tags on the HTML page. This way, PHP can generate the necessary JavaScript code based on server-side data before sending it to the client. 

<?php
// PHP code to generate JavaScript dynamically
$variable = "Hello, World!"; // Example server-side data
?>

<!DOCTYPE html>
<html>
<head>
    <title>PHP and JavaScript Example</title>
</head>
<body>
    <script>
        // JavaScript code generated by PHP
        var message = "<?php echo $variable; ?>";
        alert(message);
    </script>
</body>
</html>
