Define a server global constant or variable

Anon

I would like to define a constant or variable wich will be accessible in all of my .php pages on my entire server. That constant/variable would behave exactly the way the php-constants 'FILE', 'TRUE' and 'PHP_VERSION' does.

The use could be that I am able to write:

include(FOO . "include.inc");

Where 'FOO' would be a path to the file 'include.inc'. Then if I would like to move the include directory I would just have to change the certain variable/constant 'FOO'.

I know, there is this variable: 'include_path' in php.ini that I could set, but what if I would like to use different include-paths for dirrerent parts of my site.

According to the manual, you may be able to achieve the same effect by changing the PHP configuration on a directory-by-directory basis with .htaccess files. See "Chapter 3. Configuration." I have not tried this and don't know what limits there might be.

The approach you are thinking about also should work, and it could be achieved by inserting environment variables in the Apache configuration. See the Apache manual section covering mod_env, specifically the SetEnv directive. This also should work both in httpd.conf and .htaccess files, I think.

You can do it just fine. In all of your pages require a page (ie: require config.php). In that file define your constant (ie: define("MYCONST")) then in any page where you want that constant, use it just like a variable (ie: echo MYCONST).
