您还需要安装xdebug。

I have this variable in a big php script that I want to trace back to where/when and what value it was instantiated. Is there a function/api or debugging techniques to do this?

解决方案

If you're using PHPStorm you can set breakpoints and inspect the values of variables.

You'll need xdebug installed as well.
