.user.ini vs. php.ini

[smallcompany]

I wonder about the usage of .user.ini file on shared servers.

Would .user.ini propagate to subfolders or I need one for each folder where I want directives to be applied?
Is it possible to make it recursive like with php.ini by using suPHP_ConfigPath in .htaccess?

Is there anything you would recommend in regards of .user.ini usage, and how you see .user.ini vs. php.ini?

Thanks

As i know, .user.ini works same linke php.ini
Pointer will search the file from the document root to the file destination.
So don't need to include it in all the folders,
Just place it in root directory with the custom configuration.
You shold take a look at here : [php.net...]
