Most popular versions of PHP used by your customers are unsupported by PHP.net and as of June 21st, add PHP 5.5 to the mix of PHP versions that are no longer supported by the community.
This means that as security vulnerabilities are discovered, they will not be fixed by PHP.net in versions PHP 5.5 or older.
Here is a quick rundown on numbers:
PHP.net is the most popular server-side programming language with 82% market share and by far the fastest growing amongst it’s “competitors” with ASP.net taking only 15% of the market, according to W3Techs.com.
As depicted in the above image, PHP version 5 is used by 97.8% of all websites who use PHP, and version 5.5 is used by 20% of all the websites who use PHP version 5.
Here is how PHP.net support normally works – for two years, bugs and security issues that have been reported are fixed and are released in regular point releases.
