Remarks
PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely-used open source programming language. It is especially suited for web development. The unique thing about PHP is that it serves both beginners as well as experienced developers. It has a low barrier to entry so it is easy to get started with, and at the same time, it provides advanced features offered in other programming languages.
Open-Source
It’s an open-source project. Feel free to get involved.
Language Specification
PHP has a language specification.
Supported Versions
Currently, there are three supported versions: 5.6, 7.0 and 7.1.
Each release branch of PHP is fully supported for two years from its initial stable release. After this two year period of active support, each branch is then supported for an additional year for critical security issues only. Releases during this period are made on an as-needed basis: there may be multiple point releases, or none, depending on the number of reports.
Unsupported Versions
Once the three years of support are completed, the branch reaches its end of life and is no longer supported.
A table of end of life branches is available.
