In this video I provide a tour of KCachegrind, a tool to visualise Xdebug's profiling files.
On Linux, you should be able to install KCachegrind through your package manager.
For OSX, there is a QCachegrind homebrew formula: https://formulae.brew.sh/formula/qcac...
For Windows, you can find a binary at https://sourceforge.net/projects/qcac...
