The big question you need to get the answer for is will you be writing 'modern' PHP or maintaining 'legacy' PHP. Modern PHP using the latest tools and frameworks and modern PHP best practices isn't too bad a language. Far from my favourite, but quite decent. 'Legacy' PHP on the other hand can be a nightmare, especially if it's a system that has been around since the PHP4/5 days and still written in style of the time. I would definitely stay away from that. As to resume impact, I wouldn't overthink the language. Most decent companies care much more about what you where doing, than what language you where doing it in. Building a cutting edge micro service setup that scaled and performed really well (in PHP) should easily count in your favour.
