Not sure about that. Most companies biggest problem is finding talent employees and most experienced engineers will not want to work on a Php codebase especially one full of technical debt due to the variety of other options in languages which compile and miss out on a huge percentage of php problems before you even run basic tests.
I'm not going to make any customers happy working on a product if I hate the codebase and the language I'm working in so much I just DGAF.
