I’m using Eclipse Galileo for PHP Developers and when I create new, empty project I have 3 folders inside:
JavaScript Resources
PHP Include Path
PHP Language Library
Does Eclipse make copy of PHP for every project? And more important: can I hide it from my project navigator tree?
You are wrong, they are not folders, they are just references, which are defined within the project properties and pdt manages for you. Just look into the folder with your prefered file manager and you will not find folders with this names. So no, eclipse doesnt copy php.
And no, you cant hide them from the php navigator view. There is no obvious reason to hide them anyway.
