I got this piece of code which I'm analysing and it have this condition

if(($hint&self::HINT_WRITE  && $hint&self::HINT_NOWRITE) || ($hint&self::HINT_READ  && $hint&self::HINT_NOREAD))
{
    some code ..
}

Any Idea what '&' in '$variable&self::CONSTANT' means?

It's the bitwise `AND` operator – knittl Feb 19 '13 at 22:27

That's a very cramped-for-space bitwise AND – Michael Berkowski Feb 19 '13 at 22:27
interesting names for the constants. – didierc Feb 19 '13 at 23:01
