How to install phpseclib?
提问by Diego
I have installed Apache on my machine so I can use localhost as a PHP server. That works. Right now I am trying to use PHP to send files via SFTP to another server. I looked around a bit and saw phpseclib was recommended. I can't seem to figure out how to install phpseclib. Here are the lines that the website gave:
我已经在我的机器上安装了 Apache，所以我可以使用 localhost 作为 PHP 服务器。那个有效。现在我正在尝试使用 PHP 通过 SFTP 将文件发送到另一台服务器。我环顾四周，看到推荐使用 phpseclib。我似乎无法弄清楚如何安装 phpseclib。以下是该网站给出的行：
set_include_path(get_include_path() . PATH_SEPARATOR . 'phpseclib');
include('Net/SFTP.php');
You have to set the include path.
您必须设置包含路径。
I understand what these words mean but I have been unable to get it working. I am using a mac. My server is in /Users/diego/Sites/. Where exactly do I need to put the phpseclibfolder? What lines do I need to put in my php file so that phpseclibis included?
我明白这些话的意思，但我一直无法让它发挥作用。我正在使用 mac。我的服务器在/Users/diego/Sites/. 我到底需要把phpseclib文件夹放在哪里？我需要在我的 php 文件中放入哪些行才能phpseclib包含在内？

I got it working by installing PEAR, following this guide.
By following the guide above, I figured out that apache2 was looking for php.iniin my /etc/folder. But I ran into a problem. In my /etc/folder there was no php.inifile. But there was php.ini.defualt. So I 'saved as' php.ini.defaultto php.iniand then modified the include_path.
按照上面的指南，我发现 apache2 正在php.ini我的/etc/文件夹中寻找。但是我遇到了一个问题。在我的/etc/文件夹中没有php.ini文件。但是有php.ini.defualt。所以我“另存为”php.ini.default对php.ini，然后进行修改和include_path。
; UNIX: "/path1:/path2"
;include_path = ".:/php/includes"
include_path = ".:/Users/diego/pear/share/pear:/php/includes"
PHP is no longer throwing an error saying that phpseclibcannot be found.
PHP 不再抛出phpseclib无法找到的错误。

#add this to the php.ini file /etc/php.ini, it can be placed at the end of the file

$sftp = new Net_SFTP('555.55.55.55', 22);
if(!$sftp->login('username', 'password')) {
echo $sftp->getSFTPLog();

Thanks to Diego, for the hint to install PEAR. I got it working with the following steps:
感谢 Diego 提供安装 PEAR 的提示。我通过以下步骤得到了它：
First, install PEAR.
首先，安装PEAR。
$ wget http://pear.php.net/go-pear.phar
$ php go-pear.phar
If the wgetcommand doesn't work, please install that package, to get it working.
如果wget命令不起作用，请安装该软件包以使其正常工作。
$ sudo apt-get install wget
After successfully installing PEAR, configure it with this guide.
成功安装 PEAR 后，使用本指南对其进行配置。
The php.inifile, can be found in /etc/php5/apache2. You have to modify this file.

set_include_path(get_include_path() . PATH_SEPARATOR . 'phpseclib');will add phpseclib as a relative path. So doing include('Net/SFTP.php')will include phpseclib/Net/SFTP.phpbut that's relative to whatever your working directory is.
set_include_path(get_include_path() . PATH_SEPARATOR . 'phpseclib');将 phpseclib 添加为相对路径。这样做include('Net/SFTP.php')将包括phpseclib/Net/SFTP.php但这是相对于您的工作目录的任何内容。
PEAR often has an absolute path in the include_path. So that's something you could try doing. Putting phpseclib in some directory (prob outside of the document root) and then putting that directory into your include_path.
PEAR 通常在 include_path 中有一个绝对路径。所以这是你可以尝试做的事情。将 phpseclib 放入某个目录（文档根目录之外的 prob），然后将该目录放入您的 include_path 中。
Note that this matters more if you downloaded phpseclib from sourceforge.net or if you're on the 1.0 branch.
请注意，如果您从 sourceforge.net 下载了 phpseclib 或者您在 1.0 分支上，这会更重要。
