Hi Jordan.

Great Idea.

There are just a few questions I have:

* Is it possible to extend that system also to minor and patch versions?
* What effect has that on docker or vagrant systems? Especially on
maintainability of up-to-date versions that will have to symlink the
current version to a new binary with every version?
* what effect would that have on non-release versions?

For our development it has been intresting to be able to switch between
different minor and patch-versions of PHP so we use vagrant or docker
for different projects depending on the PHP-Version available on the
productive servers. That can then also include extensions and so on.

Alternatively I've used the prefix to distinguish between the versions
and then created symlinks to the binaries inside a bin-folder. When that
was necessary at all, as f.e. php-fpm can be called right inside the
respective prefiexed folder...

And then there's also phpenv which took rbenv as a model.

Cheers

Andreas
