    • For SQL Server Editions, PHP 5.6 or above (till PHP 8.1) with PHP XML extension enabled and Microsoft SQL Server Driver for PHP
  • Database: MySQL 5.7 or above, MariaDB 10.0 or above, Microsoft SQL Server 2008 or above.

Requirement Details

Apache (Recommended)

PHPKB will work on Apache 1.3 or Apache 2.x hosted on UNIX/Linux, OS X, or Windows. The majority of PHPKB development and deployment is done on Apache, so there is more community experience and testing performed on Apache than on other web servers. You can use the Apache 'mod_rewrite' extension to allow for SEO friendly URLs.

Microsoft IIS

PHPKB will work using IIS 5, IIS 6, IIS 7 or later, if PHP is configured correctly. To achieve SEO friendly URLs you may need to use a third party product. For IIS7 (or later), you can use the Microsoft URL Rewrite Module or a third party solution such as ISAPI_Rewrite. ISAPI_Rewrite is Apache mod_rewrite compatible URL rewriter for Microsoft IIS.

Disk Space

A minimum base installation requires at least 500 MB of disk space but you should assume that your actual disk space will be somewhat higher. For example, if you upload file attachments and images for articles, the actual disk space for your knowledge base could easily be 1GB or more (exclusive of database content, media, backups and other files).

The total file size of your PHPKB installation will depend on what you add to your knowledge base, but core files alone will take up approximately 100 to 200 MB uncompressed. The exact size depends on the edition of PHPKB you have installed.


All modern browsers are supported (IE7+, Firefox, Safari, Google Chrome, Opera) that support CSS and JavaScript.


The PHPKB knowledge base software comes with its own installer. Follow the installation tutorial.

Hardware Requirements

PHPKB knowledge base software works well on any web-server that meets its software requirements specified above. This is definitely not a processor-hungry or memory-hungry application. Numerous instances of PHPKB knowledge base software are running on shared web hosting (virtual hosting) systems and are working perfectly fine. It means you can install it on a shared hosting server too. If you would like to use a dedicated hosting or host it on a local server, you can have a look at the hardware requirements and example configurations for a reference.

User System Requirements

  • Operating System: Windows, Mac or Linux
  • Web Browser: All industry standard web browsers (Internet Explorer, Mozilla Firefox, Google Chrome, Apple Safari)
