Comment (by ryandesign):

 I don't know how swig works or how users use swig; I don't know if there
 is benefit to building for a specific version of PHP. If there is, how
 about offering variants for all the version of PHP that the PHP port
 offers. 7.2 is the latest stable, so I would suggest that should be the
 default.
