As PHP has moved to git recently everybody who works on the PHP source has to recreate his work environment. When working on PHP I have a few requirements for my working dirs. For one I want to be able to use different branches (like 5.3, 5.4 and master) at the same time and I want to quickly test different PHP configurations, like builds using thread-safety or debug mode on or off.
A simple approach for this is to use out-of-tree builds, something like that:
$ git clone ....php-src.git $ (cd php-src && ./buildconf) $ mkdir build-master-minimal $ cd build-master-minimal $ ../php-src/configure --disable-all $ make
This allows having both requirements full-filled as you can have build dirs for each branch and each configuration. Nice, but in the long run quite confusing as you always have to make sure php-src has the correct branch checked out, matching the build dir you're currently building in, else you will create a mess.
Thankfully there is a nice solution to have multiple checkouts using git-new-workdir. So one can easily setup the branches and build dirs. Now it's still quite some repetitive work to create a structure using different branches and a set of different build dirs for each branch. Therefore I've created a simple shell script to do this quickly on my different machines and pushed the script to github in case anybody wants to have a similar structure, and maybe improve the script. But be warned: The script is really an ad hoc thing for me to get started.
