使用PHP通过ssh执行shell命令

Question

我正在尝试执行一个简单的shell命令并在网页上打印结果,但结果是空的.下面是我发现的一点代码但到目前为止没有任何工作.

 <?php
            $server = "myserver";
            $username = "myadmin";
            $command = "ps";
            $str = "ssh " .$username. "@" .$server. " " .$command;

            exec($str, $output);

            echo '<pre>';
            print_r($output);
            echo '</pre>';
    ?>

试试phpseclib,那就行了.

<?php
    include('Net/SSH2.php');

    $server = "myserver";
    $username = "myadmin";
    $password = "mypass";
    $command = "ps";

    $ssh = new Net_SSH2($server);
    if (!$ssh->login($username, $password)) {
        exit('Login Failed');
    }

    echo $ssh->exec($command);
?>
