floydian,
You can have two versions of php.ini coexist on the same site using this little workaround:
* Declare a first PHP interpreter and associate it with .php file extension. It will use the default php.ini that is installed with PHP.
* Create a second php.ini with all your specific settings and put it a subdirectory (for example conf2 inside PHP installation path).
* Declare a second PHP interpreter as follows:
- Interprter: the same php-cgi.exe as the first one (no need to install a second copy)
- Arguments:
-c c:/PHP5/conf2
- Associated extensions: .phpx
Note that it is important to choose another file name extension for files that will be processed with the second interpreter and PHP scripts' file name extensions must be changed accordingly.
