Just use the native filter functions, such as http://docs.php.net/manual/en/function.filter-input-array.php
They're available since PHP 5.2!

Your tip maks no sense at all. It's the expected behaviour, since you're injecting an instance of a class (== object) with all it's attributes and methods.

Awesome tip, thanks for that. I'd remove the "rails" tag tho, since this tip is useful to any file type.

Thanks for the feedback.
That's why the title has "PSRs" in it. The idea was to make a concise title, but giving the idea that in this tip you find a tool that fix your mistakes related to the PSRs.

Any other code problems should be fixed by the programmer anyway, so...

Great tip, never heard of it before. =)
