I finally got xdebug set up and running and I’m using webgrind to understand the data.

Can someone explain how to understand the data? There’s just a bunch of terms that I’m not sure of, like: Invocation Count, Total Self Cost, Total Inclusive Cost. I also don’t understand what changing the “show percentage” does. (It defaults to 90%). Any tips on how to use webgrind to understand my php application?

    here are some personal definitions:

    Invocation Count:
    the number of times a given method or function has been called

    Total Inclusive Cost:

    total time or percentage of time spend in a given method or function

    Total Self Cost:

    Total Inclusive Cost of a function or method minus Total Inclusive Cost of the methods or functions that are called inside
