Yes, you can return false.
As for "true booleans", PHP doesn't really have a boolean type - it does
have a sense of "true" and "not true" though. You can return false (a
case-insensitive constant with the value 0) or true (whose value is
probably 1 but could really be anything other than 0 or the empty
string).
You can of course evaluate a true/false value as a regular condition...
if (someFunc()) {
// do something if someFunc returns true
} else {
// do something if someFunc returns false
}
..You get the idea.
