Honestly, I'd recommend using phpseclib, a pure PHP SSH2 implementation. Example:
老实说，我建议使用 phpseclib，一个纯 PHP SSH2 实现。例子：
<?php
include('Net/SSH2.php');
$ssh = new Net_SSH2('www.domain.tld');
if (!$ssh->login('username', 'password')) {
exit('Login Failed');
}
echo $ssh->exec('pwd');
echo $ssh->exec('ls -la');
?>
It's a ton more portable, easier to use and more feature packed too.
它更便携、更易于使用且功能更丰富。

To expand on @neubert answer, if you are using Laravel 5 or similar, you can use phpseclib much simpler like this:
要扩展@neubert 答案，如果您使用的是 Laravel 5 或类似版本，则可以使用更简单的 phpseclib，如下所示：
Run composer require phpseclib/phpseclib ~2.0
跑 composer require phpseclib/phpseclib ~2.0
In your controller add
在您的控制器中添加
use phpseclib\Net\SSH2;
use phpseclib\Net\SSH2;
Then use it in a controller method like:
然后在控制器方法中使用它，例如：
$host = config('ssh.host');
$username = config('ssh.username');
$password = config('ssh.password');
$command = 'php version';
$ssh = new SSH2($host);
if (!$ssh->login($username, $password)) {
$output ='Login Failed';
}
else{
$output = $ssh->exec($command);
}
