Hi. I just made a php "compiler" class and I fell to share it. By compiler, I mean a class which will merge all files into one, removing comments, unwanted spaces and unwanted carriage-return. It it very usefull if you always include/require a lot of files to increase speed.
here's the class :

1. Change the ROOT constant value to your root relative path.
2. Edit the dir attribute to your lib directory.
3. Edit the file attribute to the file which will contain all classes.
Here's the result:
