What are some best practices for implementing a console on a website for executing commands on the server?

Implementing a console on a website for executing commands on the server can pose security risks if not properly handled. One best practice is to sanitize user input to prevent command injection attacks. Additionally, limiting the commands that can be executed and restricting access to the console to authorized users can help mitigate potential risks. 

<?php
if(isset($_POST['command'])) {
    $command = escapeshellcmd($_POST['command']);
    if(in_array($command, ['command1', 'command2', 'command3'])) {
        $output = shell_exec($command);
        echo $output;
    } else {
        echo "Invalid command";
    }
}
?>
