The innovative mind of Rasmus Lerdorf began writing a series of Common Gateway
Interface Perl Scripts, which led to the development of PHP around 1994.
In order to view the development of PHP, the timeline given below gives us the brief view:
1995 : Lerdorf announced the release of PHP which was formally called as Personal Home Page Tools (PHP tools).
1997-2006 : There were various releases but no development in the language.
2009 : There was a stable release which involved only Security fixes and included features such as namespace support, late static bindings, jump labels, native closures.
2012-13 : The developments were “Bugs and Security Fixes”.
2014 : It will include future releases and will include various innovative features.
The universality of the language can be credited to the coders that made changes and
additions to the software that allowed it to use as script processor. Currently the current
version of PHP is 7.0 and PHP 7.1 is scheduled to release on November 2016.
