Upgrade PHP to PHP7
PHP is a popular server-side scripting language language, suited to all kinds of application development due to its flexibility. Lot of versions of PHP ( such as PHP1, PHP2, PHP3, PHP4, PHP5, PHP6, PHP7 and PHP7.xx) have come in the last 20 years. Out these versions, PHP5 has been in use for the past 13 years, it was developed by the new Zend Engine and released in 2004. This version included lots of new features such as improved support for object-oriented programming, the PHP Data Objects (PDO) extension, and numerous performance enhancements. In 2008, PHP 5 became a stable version under development. Later on more extension versions of PHP5 were added. PHP5.5 made the 64-bit x86-64 builds available for Microsoft Windows.
From 2014 to 2015, many PHP versions were developed. The numbering of the version to be released involved some debate. While the PHP 6 Unicode experiment had never been released, several articles and book titles referenced the PHP 6 name, which created some confusion among some developers regarding the new version release at that time. After voting, the name PHP 7 was chosen. PHP7 was a next generation version of PHP with advance features. It was authored by Dmitry Stogov, Xinchen Hui and Nikita Popov. PHP7 aimed to optimize PHP performance by refactoring the Zend Engine while retaining near-complete language compatibility. As of 14 July 2014, WordPress-based benchmarks, which served as the main benchmark suite for the PHP next-generation project showed an almost 100% increase in performance with PHP7. PHP7 improved compiling complex data structure which resulted in improved performance of applications. Because of the significant changes in PHP7, the Zend Engine was reworked too and is called Zend Engine 3.
Major versions of PHP are allowed to break backward-compatibility of code and therefore PHP 7 presented an opportunity for other improvements beyond PHP. In particular, it involved following changes:
- Reduced web applications incompatibility and compliance issues
- Better security for message transmission
- Better security encrypted storage of sensitive data
- Improved efficiency in processing
- Requires a higher standard of coding from developers
- Removes deprecated functions
- Better for heavy traffic sites
- Improvement in Speed
- Reduced server memory usage
- Improved Error Handling
- Type declarations
- Encrypted number generation
