It costs time and it's completely not necessary. This is a bug.

No, it's not a bug. It's definitely an intended behavior. PHP does it's best to do the 'right thing' in the most common cases. Because of the way it works, effectively, comparing strings that 'look like numbers' as if they were numbers makes life much, much easier. If you want to enforce a string comparison, use strcmp().

    We should document this behavior then - it could lead to problems
    that are very hard to track down!
