PHP7 Next Generation Of PHP With PHPNG

Next Generation of PHP

Initially PHP started as PHP/FI in 1994 written in c programming language by Rasmus Lerdorf for his personal use.

Later Rasmus recreated PHP with database interaction to use with advance PHP framework in 1995 and released source code open to all developers to modify and reporting bugs.

So basically PHP follows C structure and its variable declaration is similar to Perl syntax for easy adopt by developers who is familiar with C and similar language.

PHP Versions

PHP Versions

PHP3: php3 was the first version of PHP release with Object oriented programming support and database connectivity with MySql, PostgreSql by new PHP Development Team in 1998.

PHP4: php3 was not designed to handle complex applications efficiently to make PHP more powerful and capable to work with complex application with high efficiency new PHP engine designed name as Zend Engine.

PHP4 was based on Zend Engine with high security and efficiency to meet complex applications expectation this took nearly two years and then launched in 2000.

PHP5: After further improvements in php4 new version of PHP launched which is later became the most popular version of PHP in 2004 with Zend Engine 2.0

PHP6: PHP developers team was working to change some Unicode binary to make next generation PHP but during development things become complex and another project started with name PHP7 which have features those expected in PHP6 and other new features.

Also many blog post and information related to PHP6 shared by many communities even some authors launched new php books cover page title as PHP6 but later they changed and updated once officially declare that PHP will skip PHP6 and will be launch new version name as PHP7, So no PHP6 exist officially.

PHP7: The latest generation of PHP which is mainly developed to make PHP execution fast, and they successfully achieved twice faster speed then old versions of PHP.

PHP7 is based on new engine name PHPNG  (PHP Next Generation)

HHVM is developed by Facebook team from open source PHP project and become fastest engine. Later PHP team used the similar concept which is used in HHVM and developed New Generation PHP which is more faster than HHVM.

PHP7 is officially launched in 2016 with twice fast speed than old PHP.

PHP7 is faster than all old PHP versions and some other server side scripts
