仅在子文件夹中将htaccess更改为PHP $ _SERVER ['DOCUMENT_ROOT']，并将其保留在根目录中而无需更改

Question

I have 2 websites. One is in the /public_html and the second in sub folder /public_html/site2 .

I want to change the $_SERVER['DOCUMENT_ROOT'] in the /site2 directory so its $_SERVER['DOCUMENT_ROOT'] will start from /public_html/site2 instead of public_html . BUT the first site that in the root directory, must be left without the change so it will have the original $_SERVER['DOCUMENT_ROOT'] that is public_html .

I am trying to change the .htaccess that under the /site2 directory, but didn't find any solution yet.

Can you help, please?

Answer 1

You could globally override that variable within PHP, by using the php.ini auto_prepend_file setting, which can also be set using .htaccess again:

php_value auto_prepend_file ./override_docroot.php

And that script would then "globally" adapt your environment:

<?php
   $_SERVER["DOCUMENT_ROOT"] = "..."; 

But I really recommend you to create your own constant like "APP_BASE_URL" like this:

define('APP_BASE_URL','http://www.mywebsite.com', FALSE);   

And then call it like:

<img src="<?php echo APP_BASE_URL; ?>/img/path/img.jpg">

Gook Luck!
