It's unfortunate that Debian packages do not contain symbolic links for base libraries to their
versioned counterparts, and we need to install the `-dev` packages for that. All required packages
are now included in the Docker image's runtime dependencies, and the `static` build tag is made to
include the correct ones.
This allows for building binaries against `go-php` without needing an accompanying version of the
PHP library. To build a static version of `go-php`, simply set `STATIC=true` as a Make flag, e.g.:
make docker-build STATIC=true
The resulting `go-php` library will be placed in `.build/env/GOPATH/pkg/...` by default, and can be
used directly, but using the Docker image as a build environment will also work.
This adds PHP 7.2.1 as a new target, and updates existing PHP versions to their latest numbers. Be
aware that PHP 7.2.x is as-of-yet untested -- and expected to be buggy.
All PHP builds in Docker are now made against a single-unified Dockerfile, which accepts the PHP
version to target in the `PHP_VERSION` argument. Source files are currently not verified (other than
being downloaded from a secure location, as we will eventually move to using the official `php`
Docker images as a base, as soon as these catch up to latest versions of Debian.
