Unlimited Hierarchy Levels
Many competitor products have only three or four tiers of content hierarchy hardcoded in their knowledge base. There are workarounds, but the ideal would be between zero and infinite levels of documentation structure. PHPKB knowledge base software does not have any such restriction or limit on the number of category levels.
With PHPKB, you have "Flexible Hierarchy" which means you can create unlimited levels of categories as per your requirements. This is one more area where PHPKB has advantage over its competitors.
If you have a very small support center (under 10 articles) then zero is best. If you have hundreds or even thousands of pieces of technical guides (knowledge articles) then you may need three, four, or more levels of depth. Variable or unlimited hierarchy tiers gives you this flexibility.
