提问by Samad
I have a web site made by wordpress and I made some php files that i want to execute and for some reason I need to require_once(/wp-includes/class-phpass.php) but I got Failed opening required Error, there is a htaccess file in root folder and it doesn't exist in wp-includes folder the htaccess contain this:
我有一个由 wordpress 制作的网站，我制作了一些我想执行的 php 文件，出于某种原因，我需要 require_once(/wp-includes/class-phpass.php) 但我打开失败，需要错误，有一个htaccess 文件在根文件夹中，它在 wp-includes 文件夹中不存在，htaccess 包含以下内容：
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

Assuming this is your literal code:
假设这是您的文字代码：
require_once('/wp-includes/class-phpass.php');
No wonder the file can't be found, as requireoperates on the filesystem level, so you probably need something like /var/www/mysite/wp-includes/class-phpass.phpinstead.
难怪找不到文件，因为require在文件系统级别上操作，所以您可能需要类似的东西/var/www/mysite/wp-includes/class-phpass.php。
You should be able to get it work like this:
你应该能够让它像这样工作：
require_once $_SERVER['DOCUMENT_ROOT'] . '/wp-includes/class-phpass.php';
This inserts the current root path of the web site before the subpath. $_SERVER['DOCUMENT_ROOT']is by default the only semblance PHP has of a 'root path' unless you teach it better.
这会在子路径之前插入网站的当前根路径。$_SERVER['DOCUMENT_ROOT']默认情况下，除非你更好地教它，否则它是 PHP 唯一的“根路径”。

As mentioned in the comment, require is a filesystem-local procedure - it doesn't process the htaccess rules.
正如评论中提到的， require 是一个文件系统本地过程 - 它不处理 htaccess 规则。
You are trying to
你正试图
require_once(/wp-includes/class-phpass.php);
this is looking in your machines root for /wp-includes/
这是在您的机器根目录中查找 /wp-includes/
This would work if your wordpress is installed in the document_root (burt is not the recommended way):
如果您的 wordpress 安装在 document_root 中，这将起作用（burt 不是推荐的方式）：
require_once($_SERVER['DOCUMENT_ROOT'] . '/wp-includes/class-phpass.php');
But you should use this:
但是你应该使用这个：
$install_path = get_home_path();
require_once($install_path. '/wp-includes/class-phpass.php');
as referenced from this codex page: http://codex.wordpress.org/Function_Reference/get_home_path
从此法典页面引用：http: //codex.wordpress.org/Function_Reference/get_home_path
If you are making scripts that need to use the wordpress core, but aren't executed from within the scope of wordpress itself, then you would need to do the following:
如果您正在制作需要使用 wordpress 核心但不在 wordpress 本身范围内执行的脚本，那么您需要执行以下操作：
define('WP_USE_THEMES', false);
global $wp, $wp_query, $wp_the_query, $wp_rewrite, $wp_did_header;
require( $_SERVER['DOCUMENT_ROOT'] . '/path/to/wp-load.php');
$install_path = get_home_path();
require_once($install_path. '/wp-includes/class-phpass.php');
