Is it possible to directly read keyboard inputs using PHP?

It is not possible to directly read keyboard inputs using PHP as PHP is a server-side language and does not have access to client-side keyboard events. To capture keyboard inputs in PHP, you would need to use JavaScript to capture the keyboard events on the client-side and then send that data to the server using AJAX requests. 

// This is an example of how you can capture keyboard inputs using JavaScript and send them to the server using AJAX requests

// HTML file with JavaScript code
<!DOCTYPE html>
<html>
<head>
    <title>Keyboard Input</title>
</head>
<body>
    <input type="text" id="inputField">
    <script>
        document.getElementById('inputField').addEventListener('keyup', function(event) {
            var key = event.key;
            // Send the key to the server using AJAX
            var xhr = new XMLHttpRequest();
            xhr.open('POST', 'process_input.php', true);
            xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
            xhr.send('key=' + key);
        });
    </script>
</body>
</html>

// PHP file to process the keyboard input
<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $key = $_POST['key'];
    // Process the keyboard input here
    echo "Key pressed: " . $key;
}
?>
