Default value of suhosin.perdir is 0. It can accept one or more values l, e, g, ... For example, suhosin.perdir = "lge" (FIXME?). When perdir is turned on, you may put local configuration in application's directory. (However, php-fpm doesn't use those *.ini files.)

The feautre isn't documented, but you can find it in the source code of the main library suhosin.c:
