SSH接続を使用してみませんか？コマンドを抽象化し、入力/出力をリダイレクトし、完全に制御できます。
必要なだけの権限を持つ純粋でクリーンなシェルを誰かに提供し、パスワードをSSH2 :: Connect（）にPOSTして、シェルを開くことができます。
私はphpSSH2拡張機能を操作するための素晴らしいクラスを作成しました。多分それはあなたを助けるでしょう。（そしてそれはまた安全なファイル転送をします）

$ssh = new SSH2($settings['host']);
if( $ssh->connect($settings['username'], $settings['password']))

flush();
