List some of the features of PHP7.

Scalar type declarations

Scalar type declarations come in two flavours: coercive (default) and strict. The following types for parameters can now be enforced (either coercively or strictly): strings (string), integers (int), floating-point numbers (float), and booleans (bool). They augment the other types introduced in PHP 5: class names, interfaces, array and callable.

Return type declarations

Null coalescing operator (??)

Spaceship operator

Constant arrays using define()

Anonymous classes

Closure::call method

Group use declaration

Generator return expressions
