+# Debugging PHP
+
+This part covers debugging possibilities for the builds produced by the native VS compilers.
+For the cross compiled builds produced with toolsets other than VC++, please check the
+documentation for the corresponding toolsets. In any case, general principles on debugging
+native programs apply.
+
+Either a debug build of PHP or enabled debug symbols are required to be able to debug PHP.
+A debug build is usually more suitable for the development process and can be produced by
+adding `--enable-debug` to the configure options. A release build with debug symbols can
+be produced by adding `--enable-debug-pack`. These options are mutually exclusive.
+
+## Debugging with Visual Studio
+
+- Configure with either `--enable-debug` or `--enable-debug-pack`.
+- A debug build might bring better experience for dev, but sometimes you want to debug a release build.
+- `nmake run ARGS=yourscript.php DEBUGGER=1`, that will open a Visual Studio window.
+- Any additional runtime options for PHP or the script executed go to ARGS, too.
+- Select `Debug -> New Breakpoint -> Function Breakpoint` and add a function where the debugger should break.
+- Click `Start`.
+
+Adding a breakpoint before starting debugging might be not necessary, if a crash is debugged. When such a script runs
+under the debugger, the debugger will stop at the crashing point. In that case, a breakpoint can be added
+around the crashed code directly.
+
+## Debugging test suite with Visual Studio
+
+The [Microsoft Child Process Debugging Power Tool](https://marketplace.visualstudio.com/items?itemName=vsdbgplat.MicrosoftChildProcessDebuggingPowerTool)
+plugin for Visual Studio is required. After installing it, following these steps
+
+- `nmake test TESTS=ext/myext/tests/sometest.phpt DEBUGGER=1`
+- Select `Debug -> Other Debug Targets -> Child Process Debugging Settings` and enable child process debugging.
+- If necessary, add a breakpoint and start debugging as described in the previous section.
+
+## Debugging with WinDbg
+
+PHP can also be debugged with the tools from the WinDbg package. There is currently no way
+implemented in the Makefile to start the WinDbg integrated, so it needs to de done manually.
+Either a debug build or a release build with debug symbols is still required, as described
+previously.

+# Support

 - The VC++ toolset is still requried, even if another compiler, fe. clang, is intended to be used.
 - `task.exe` is not a console application, some systems might not propagate exit code except the batch is explicitly run from `cmd /c`, etc.
 - `7za` should be prefered over `unzip` and `zip` for compatibility reasons.
