Upgrading from unsupported to supported PHP versions

You own a company that runs one or more PHP applications in production.

You have realized that one or more of these applications use a PHP version that has reached its end of life:

  • PHP 5.0 (security support ended on September 4, 2005)
  • PHP 5.1 (security support ended on August 24, 2006)
  • PHP 5.2 (security support ended on January 6, 2011)
  • PHP 5.3 (security support ended on August 14, 2014)
  • PHP 5.4 (security support ended on September 14, 2015)
  • PHP 5.5 (security support ended on July 10, 2016)
  • PHP 5.6 (security support ended on December 28, 2018)
  • PHP 7.0 (security support ended on December 3, 2018)
  • PHP 7.1 (security support ended on December 1, 2019)
  • PHP 7.2 (security support ended on November 30, 2020)
  • PHP 7.3 (security support ended on December 6, 2021)
  • PHP 7.4 (security support ended on November 28, 2022)

You understand that these applications may be:

  • more insecure to run because of potential security vulnerabilities
  • more challenging to host because of the lack of support for unsupported PHP versions from PHP hosting providers
  • more expensive to host because you can not benefit from performance improvements in supported PHP versions
  • more expensive to maintain because of the lack of support for PHP packages using unsupported PHP versions
  • more expensive to maintain because you can not find developers who have experience with outdated PHP versions

But you have decided to upgrade these applications to a PHP version with security support:

  • PHP 8.0 (security support ends on November 26, 2023)

Or even better, you have decided to upgrade these applications to a PHP version with active support:

  • PHP 8.1 (active support ends on November 25, 2024)
  • PHP 8.2 (active support ends on December 8, 2025)

However, you lack the resources because you do not have an internal team of developers, external agencies, or freelancers capable and willing to take up the task.

As an experienced Software Engineer who started learning PHP in 2001, I can upgrade your applications from unsupported to supported PHP versions.
