Docker Image to Hack the PHP Interpreter

A convenient Docker image to track PHP bugs (segmentation faults), to develop extensions or the PHP interpreter itself.

Build

git clone https://github.com/dunglas/php-dev-docker
cd php-dev-docker
docker build -t php-dev .

Basic usage:

docker run --cap-add=SYS_PTRACE --security-opt seccomp=unconfined -it php-dev

Debug a Local PHP Script Using GDB

docker run --cap-add=SYS_PTRACE --security-opt seccomp=unconfined -v ./:/app/ -it php-dev gdb php /app/my-script.php

Then, type r to execute the script.

If the program segfaults, type bt to get a backtrace.
