How to get the current coverage of php web application in real time?

Question

I want to test a php web application, and I need to get the current coverage in real time after running the application, like nyc and jacoco.

For example, after I manually complete the registration, I test the current coverage, and then after I manually complete the login, I test the current coverage, etc.

Is there any way to avoid interrupting the web program and not using test cases during the test? I looked at php-code-coerage and it seems it can’t be achieved?
