How can monitoring and auditing be implemented to track system commands executed through a web interface in PHP?

To monitor and audit system commands executed through a web interface in PHP, you can implement logging functionality within your PHP code. This logging mechanism can capture the commands being executed, along with additional information such as the user who initiated the command and the timestamp. By reviewing these logs regularly, you can track and audit the system commands executed through the web interface.

// Log the system commands executed through the web interface
function logSystemCommand($command, $user) {
    $logFile = 'system_commands.log';
    $logMessage = date('Y-m-d H:i:s') . " - User: $user - Command: $command" . PHP_EOL;
    
    file_put_contents($logFile, $logMessage, FILE_APPEND);
}

// Example usage
$command = 'ls -l';
$user = 'admin';
logSystemCommand($command, $user);
