Even though I'm familiar with
rbenv
, when I sawphpenv
at first, I was confused a little bit to understand about thatphpenv
is nothing but tiny wrapper ofrbenv
entirely.I felt like what is
PHPENV_ROOT
and howRBENV_ROOT
does a meaningful forphpenv
. Once I know, It's simple to understand, and I love the way what you selected.Since
phpenv
is a great tool, it's suitable not only development tool but also production-use.So I add tiny tips to README how to install
phpenv
as system-wide to grasp howphpenv
works.I'm not sure whether you feel it's not the way as you intended, then it's OK.
Thanks!
