Hide specific class fields from print_r or var_dump

Question

Is it possible to hide a specific class fields from print_r ?

Answer 1

Both print_r() and var_dump() will give you everything.

Various Reflection classes have a getDocComment() method to get the /** doc comment */ for classes, methods and properties.

Utilising doc comments to denote what should and should not be output, you can quite easily create a dumping class to achieve what you want.
