What alternative solutions exist for creating a browser-based shell for executing PHP commands and displaying output?

The issue is creating a browser-based shell for executing PHP commands and displaying output. One solution is to use a combination of HTML, JavaScript, and PHP to create a simple web interface where users can input PHP commands and see the output displayed on the page. 

<!DOCTYPE html>
<html>
<head>
    <title>PHP Shell</title>
</head>
<body>
    <form method="post">
        <input type="text" name="command" placeholder="Enter PHP command">
        <input type="submit" value="Execute">
    </form>
    <?php
    if(isset($_POST['command'])){
        $output = shell_exec($_POST['command']);
        echo "<pre>$output</pre>";
    }
    ?>
</body>
</html>
