Return type declarations in PHP7

Today the maintainers of PHP voted on whether they should add return type declarations in PHP7.  And guess what, it passed!

So in PHP7 you can declare this function that guaranties that an array will be returned.

function foo(): array {
return [];

You will be able to add a return type for closures, function, generators and class methods. Code which does not declare a return type will continue to work exactly as it currently does.
