如何使用composer设置phpseclib

Question

I have downloaded phpseclib using composer and it created the path /var/www/html/dom/vendor/phpseclib/phpseclib/phpseclib

Now I am not sure where I include my test.php file to run it. Continuously getting the error " Fatal error: Class 'phpseclib\Net\SSH2' not found in /var/www/html/dom/vendor/phpseclib/phpseclib/phpseclib/Net/SFTP.php on line 50"

My code of test.php is

<?php
set_include_path(get_include_path() . PATH_SEPARATOR . '/phpseclib');
include('Net/SFTP.php');

$sftp = new Net_SFTP('domain');
if (!$sftp->login('user', 'pass')) {
    exit('Login Failed');
}

// outputs the contents of filename.remote to the screen
echo $sftp->get('filename.remote');
// copies filename.remote to filename.local from the SFTP server
//$sftp->get('filename.remote', 'filename.local');

?>

Composer generates an autoloader. You don't have to care about including things manually. Just do:

include '/var/www/html/dom/vendor/autoload.php';
