I am trying to include a php file in a page via
require_once(http://localhost/web/a.php)
I am getting an error
Warning: require_once(): http:// wrapper is disabled in the server configuration by allow_url_include=0
I changed allow_url_include=1 in the php.ini and that worked but I don't think that everybody will let me change their php.ini file.
So, is there any way to accomplish this?
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:
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).
You have to put the path to the file. For example:
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)
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');
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.
Replacing require_once get_template_directory_uri() . '/path-to/my-file' with require_once dirname( __FILE__ ) . '/path-to/my-file' did the trick.
try to use
<?php require_once($_SERVER['DOCUMENT_ROOT'].'/web/a.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.
require_once dirname(__FILE__)."/../../includes/enter.php";
This code will get the file from 2 directory outside of the current directory.
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.INI file
Find 'allow_url_include'
replace it with value 'on'
allow_url_include=On
Save you php.ini & RESTART you web-server.
echo file_get_contents('http://localhost/web/a.php'); //Best Example
