Significant changes to PHP have increased the performance of sites that use the language dramatically. In fact, it is estimated that PHP 7 offers a 100% improvement in performance speed over PHP 5.6. This major improvement in speed allows web developers to create sites that provide interesting and engaging interactive features that still respond to user input as quickly as modern web users have come to expect.
Another motivation for the development of PHP 7 is the need to develop scripting languages that run more efficiently. This demand is driven by two factors: the need to reduce costs and the need to reduce power consumption to protect the environment. Compared to PHP 5.6, PHP 7 places substantially reduced demands on servers, which makes it a more cost-effective and environmentally friendly choice, as comparatively less energy is needed to power servers running PHP 7 applications.
There are certain things that appears new in PHP 7, some are mention below;
- PHP#NG– the New Zend Engine for PHP 7
Currently, the PHP 5.X uses Zend Engine II which powerfully enhances the functionality of the PHP 5.x based websites and adds the extensible object model, providing performance boost to the language.
- Twice the speed of Previous Versions
One of the most undeniable and visible advantages of the new PHPNG engine is the improvement in performance. It also includes Just-In-Time (JIT) that provides the compilation done in run time – avoiding it to be done before the code execution.
- Simplifies Error Handling
For PHP coders (until now), handling catchable fatal and just fatal errors was never an easy task. The newest Engine Exceptions allows you to replace such errors, keeping exceptions. Just in case the exception remains undiscovered, PHP will to return to the same fatal errors as they have in the 5.x version.

- 64-Bit Windows Systems Support
For those who didn’t know, PHP is a vital member of LAMP stack. This concludes that LINUX is their native environment, but it is possible to use PHP on Windows system as well. The 5.x version does not provide the 64-bit integer as of yet.
On the other hand, PHP 7 is set to change this by launching their consistent support to 64-bit, meaning that it will give both natives the support of large files and 64-bit integers. It gives developers the confidence of running language on their 64-bit Windows system as well.
- Gives out Accurate Type Declarations
To improve the feature even more, PHP 7 has introduced four new type declarations for the scalar types:
- Addition of Anonymous Classes
With the benefit of adding Java and C+, PHP 7 allows programmers to add any anonymous class to their code. For those who do not know, an anonymous class is a class that has no name. Nonetheless, the object being instantiated has similar functionality as the named class object.
- Provides You with A lot of Space
The main aim of PHP 7 was to set up free space in order to provide improvements in this version. This is why it was important to get rid of the deprecated functionalities, along with the unsupported, old Server extensions and APIs. This largely helped in giving out free space.
In PHP 5, the removed items are deprecated for some time. However, if you are thinking about running your old PHP version app, PHP 7 may break the code.
