Answer / Yashu Mathur
PHP 7 introduced several important features, including:
1. Scalar Type Declaration - Allowing developers to declare the types of variables at the time of declaration for better type safety and improved performance.
2. Return Type Declaration - Enabling developers to specify the return type of a function or method.
3. Anonymous Classes - Allowing the creation of a class without giving it a name.
4. Spaceship operator (<=>) - A new comparison operator that returns 0, 1 or -1 for equal, greater than and less than respectively.
