For now, PHPBrew supports PHP versions from 5.3. therefore features that are not implemented in PHP 5.3 couldn't be used inside PHPBrew.

Type Hinting

class, array type hinting CAN be used.
callable CANNOT be used since it's implemented in PHP 5.4.
scalar type hinting like int, string, float CANNOT be used since it's implemented in PHP 7.0.
