Are you using an outdated PHP version?
Written by: Isabelle

By the end of 2018 PHP 5.6 and 7.0 will cease to exist. If you are using these PHP versions you should upgrade to a newer PHP version. The reason for this is to ensure your website will continue working, remain fast and secure.

What is PHP?

PHP is short for Hypertext Preprocessor. This is a script language running on web servers to point websites with dynamic content (search engines and blogs for example).

Make sure the website is compatible

Upgrading from 5.5 to 7.X should work flawlessly, but we recommend you check the program code for your website to make sure.

You will need to do the following:

  • Make sure the latest version of your script (for example WordPress/Joomla/OpenCart) is installed on your hosting.
  • Make sure all themes and plugins you are using is updated and compatible with PHP 7.X. If you have updated them any time during the last year, they are probably ready for PHP 7.1+. Contact your website developer if you have questions regarding your website being compatible with new PHP versions.
  • The guides below contain checkpoints you should go through for your website in order to be ready for upgrade to 7.X.

Upgrade from 5.6 to 7.0
Upgrade from 7.0 to 7.1
Upgrade from 7.1 to 7.2

If you have used mysql_* -functions for your website, you will need to replace them with mysqli or PDO. If you have a newer version of WordPress/Joomla/OpenCart, you are already using the correct database connection.

*PRO ISP supports all PHP versions, even though some of these will cease to exist.
