PHP Version

We specifically test it on 5.6-7.2 and I use it on 7.2 every day. I haven’t used 7.3 at all myself, but I’ve looked through the major changes and didn’t see anything that should be a problem on 7.3.
Do let me know if you try it on 7.3 and encounter any issues at all: https://ewww.io/contact-us/

I added 7.3 to our unit testing workflow today, and it passed with flying colors: https://travis-ci.org/nosilver4u/ewww-image-optimizer/builds/479703321

Great. Thank you
