Warning: require_once(): http:// wrapper is disabled in the server configuration by allow_url_include=0
提问by Gags
I am trying to include a php file in a page via
我正在尝试通过在页面中包含一个 php 文件
require_once(http://localhost/web/a.php)
I am getting an error
我收到一个错误
Warning: require_once(): http:// wrapper is disabled in the server configuration by allow_url_include=0
I changed allow_url_include=1in the php.ini and that worked but I don't think that everybody will let me change their php.ini file.
我更改allow_url_include=1了 php.ini 并且有效，但我不认为每个人都会让我更改他们的 php.ini 文件。
So, is there any way to accomplish this?
那么，有没有办法实现这一点？

The warning is generated because you are using a full URL for the file that you are including. This is NOT the right way because this way you are going to get some HTML from the webserver. Use:
生成警告是因为您正在使用包含的文件的完整 URL。这不是正确的方式，因为这样您将从网络服务器获取一些 HTML。用：
require_once('../web/a.php');
so that webserver could EXECUTE the script and deliver its output, instead of just serving up the source code (your current case which leads to the warning).
以便网络服务器可以执行脚本并提供其输出，而不仅仅是提供源代码（您当前的情况会导致警告）。

I had this same error while trying to include a PHP file in my Wordpress theme. I was able to get around it by referencing the file name using dirname(__FILE__). I couldn't use relative paths since my file was going to be included in different places throughout the theme, so something like require_once '../path-to/my-file'wouldn't work.
我在尝试在我的 Wordpress 主题中包含一个 PHP 文件时遇到了同样的错误。我能够通过使用dirname(__FILE__). 我无法使用相对路径，因为我的文件将包含在整个主题的不同位置，所以类似的东西require_once '../path-to/my-file'不起作用。
Replacing require_once get_template_directory_uri() . '/path-to/my-file'with require_once dirname( __FILE__ ) . '/path-to/my-file'did the trick.
更换require_once get_template_directory_uri() . '/path-to/my-file'用require_once dirname( __FILE__ ) . '/path-to/my-file'的伎俩。

You have to put the path to the file. For example:
您必须输入文件的路径。例如：
require_once('../web/a.php');
You cannot get the file to require it from internet (with http protocol) it's restricted. The files must be on the same server. With Possibility to see each others (rights)
您无法从 Internet（使用 http 协议）获取文件以要求它受到限制。这些文件必须在同一台服务器上。有机会见到对方（权利）
Dir-1 -
> Folder-1 -> a.php
Dir-2 -
> Folder-2 -> b.php
To include a.php inside b.php => require_once('../../Dir-1/Folder-1/a.php');
To include b.php inside a.php => require_once('../../Dir-2/Folder-2/b.php');

require_once('../web/a.php');
If this is not working for anyone, following is the good Idea to include file anywhere in the project.
如果这对任何人都不起作用，那么以下是在项目中的任何位置包含文件的好主意。
require_once dirname(__FILE__)."/../../includes/enter.php";
This code will get the file from 2 directory outside of the current directory.
此代码将从当前目录之外的 2 目录中获取文件。

WORDPRESS is having this error mostly:
SOLUTION:
Locate your PHP installed directory on Remote live hosting SERVER or "Local Server"
In case of Windows os
for example if you using xampp or wamp webserver. it will be in xammp directory
'c:\xammp\php'
Note:For Unix/Linux OS, locate your PHP directory in Webserver
Find & Edit PHP.INIfile
Find 'allow_url_include'
replace it with value 'on'
allow_url_include=On
Save you php.ini& RESTARTyou web-server.
WORDPRESS 主要出现此错误：
解决方案：
在远程实时托管服务器或“本地服务器”上找到您的 PHP 安装目录
，例如，如果您使用 xampp 或 wamp 网络服务器，则
在 Windows 操作系统的情况下
。它将位于 xammp 目录 'c:\xammp\php'
注意：对于 Unix/Linux 操作系统，在 Webserver
Find & Edit PHP.INI文件中找到您的 PHP 目录
查找'allow_url_include'
将其替换为值 'on'
allow_url_include=On
Save你php.ini&重新启动你的网络服务器。
