What is the difference between the phpcms column and category?

The core of CMS is content. Each content can have different models and designs, but it generally has a corresponding topic, which is also called a category. However, in addition to column management, phpcms also provides category management. Under what circumstances do you need to set a category?

 

In phpcms category management, you can set multiple topics to one category. When you post an article under Topic A, set this article to A category, then you can display it by calling the column list or category list, that is, adding one more category.

In phpcms, categories are used to reclassify topics. That is, column grouping.
