Is there any way to lock access to some built-in php functions, eg rmdir(), and make permission to some other function/method/object to access it?

You can override functions with runkit_function_redefine, but you must also set
runkit.internal_overridein php.ini otherwise you can only override functions in user space.Once you have overridden
rmdir()you can make it do anything you want: Do nothing, only work in certain directories, only work when there is a session variable set, etc…I haven’t tried ADP before, but you could also use override_function and rename_function. You could rename
rmdir()tormdir_hidden()and override the built-in name to call the new name given certain conditions. It would still be possible to callrmdir_hidden(), but only if the coder knows what it has been renamed to.By the way – I don’t think it’s really a good idea to be redefining built-in functions in PHP. Maybe before you implement this, you should take a good look at what you are doing and why you’re doing it. In all the PHP projects I’ve worked on, I’ve never seen or considered overriding a built-in function.
