1- Zend Application Engine

The Zend Engine has been powered by PHP 4 since 1999. Zend is an open source application engine written in C that interprets the PHP programming language. In PHP 5.X versions, the first Zend Engine uses the Zend Engine II, which provides an improved extensible object structure and better performance with more advanced features.

With PHP 7, the application engine PHP # NG (Next Generation) is used.

2- Performance

Thanks to the PHPNG application engine, it is possible to get twice the performance in projects with PHP 7. Added simultaneous running compilation while optimizing memory usage.

3- Enhanced Windows Support

While PHP is native to Linux, it can also run on Windows systems. Because PHP 5.x does not support 64-bit Integer or large files, it was considered an experimental version in 64-bit architectures.

PHP 7.X is now available as a stable release on 64-bit Windows systems, supporting 64-bit Integer and large files.

4- New SpaceShip and Null Combiner Operators

The Spaceship operator is used in RFC under the name of Unified Comparison Operator. This new operator is displayed as ‘<=>.. Operator is called ‘spaceship için because it resembles a spaceship.

Returns 0 if the two values are equal with Spacehip, 1 if the left is greater, and -1 if the right is greater. This operator is also referred to as directional comparison operator in Perl and Ruby.

Null combiner operator is used as ‘??.. Checks if an object exists and returns a default value if it does not exist.

5- Type of Notifications

It is now possible to prevent unwanted rotation types by defining the type of rotation of a function. This feature, which is available in other languages and improves code quality, comes with PHP 7.x.
