I'm using VS Code and particularly the "PHP" extension to open cachegrind files that I have xdebug generating. When I open the file in Qcachegrind, it shows everything correctly including call times. But opening the profile file in VS Code shows all call times as "0.00ms". Why could this be?
Your Xdebug version is no longer supported. Only Xdebug 3 is. I can't see anything wrong with your cachegrind file (mostly, because it's all squished in one line), so I would recommend you file a bug report with the VS Code PHP Plugin people: https://github.com/xdebug/vscode-php-debug/issues
