PHP 7 is a major release of PHP programming language on December 3, 2015. It is an open source scripting language used for the development of web applications. It uses new Zend Engine 3.0 to improve the performance of the application twice and also provides 50% better memory consumption than PHP 5.6.
Pros of PHP 7:
1. The Name PHP 7 (Not 6):
The current stable release uses the version number PHP 5.6. The development team decided not to use the name PHP 6 for the next major release and they named as PHP 7.
2. Usage of New Zend Engine:
PHP 7 uses the brand new Zend Engine and it is designed for today’s workload which is an ultimate choice for web developers.
3. Twice the speed:
The new Engine improves the performance two times faster than PHP 5.6 and serves more concurrent users without adding any hardware.
Cons of PHP7:
1. Development Cost:
It is costly to develop the applications which are custom made.
2. Lost Backup:
The backup will be lost after any update in case of any outages.
3. Validation Automation:
The system has no human oversight and the judgments are made by the system rather than a rational person.
