使用PHP为Apache设置实际的DOCUMENT_ROOT

Question

I'm trying to have several versions of the same PHP application in different directories. The application is written so that it has to be in Apache's Document_root.

I have tried $_SERVER['DOCUMENT_ROOT'] = '/htdocs/version2'; but that only works for things being included using $_SERVER['DOCUMENT_ROOT'].'filename.php' .

All other files executed is in the original root /htdocs/version1.

How can I make the document_root to actually change for a PHP session and not just setting the variable $_SERVER['DOCUMENT_ROOT'] ?

Answer 1

You don't need to do anything what you're just doing (what you wrote just now at least, like server stuff).

Situation 1.

If you want to use 2 folders as a separate websites (on a local machine), just copy those 2 folders in a htdocs folders and youre done. Use

http://localhost/vesion1 //version 1 is actually your copied folder name.. and version2 also

http://localhost/vesion2

entries to access them.

ps:if this aint gonna work, you should edit your website configuration .php file and change main url / path to version1 /or version 2 ie! (That is your problem actually, not "server root".)

If you have database driven url set, you should create new DB for your copy/pasted website (or force new main url/path manually).

For ie.. you can have 10 "versions" with only one DB, or 10 versions with 10 DBs (databases).

Situation 2.

If you want to run 2 versions/sites using one index.php (root index) - what are not 2 versions actually, but more like a "2 websites in one" - you should edit .htaccess file to jump over root index / or not.

I'm kinda confused what youre trying to achieve but I guess situation 1 is a go (if you're trying to do this on a local machine).
