/**
|

* Pure-PHP implementation of SCP.
|
||||
*
|
||||
* PHP version 5
|
||||
*
|
||||
* The API for this library is modeled after the API from PHP's {@link http://php.net/book.ftp FTP extension}.
|
||||
*
|
||||
* Here's a short example of how to use this library:
|
||||
* <code>
|
||||
* <?php
|
||||
* include 'vendor/autoload.php';
|
||||
*
|
||||
* $ssh = new \phpseclib\Net\SSH2('www.domain.tld');
|
||||
* if (!$ssh->login('username', 'password')) {
|
||||
* exit('bad login');
|
||||
* }
|
||||
* $scp = new \phpseclib\Net\SCP($ssh);
|
||||
*
|
||||
* $scp->put('abcd', str_repeat('x', 1024*1024));
|
||||
* ?>
|
||||
* </code>
