Recommend a most useful open source free enterprise website building system, PHP+MySQL.

This is very much. The most commonly used are the three models mentioned by LZ himself. As for their differences, they are mainly reflected in the content of a website. When the content of the website reaches a certain amount, the performance of these three modes will be different. Weaving dreams

If LZ wants to try other CMS, I can recommend several: Drupal, DO-CMS, Destoon B2B website management system, Knife website building system, AKCMS, AutoCMS, Alpha CMS, Arlicle and so on. . Actually, there are many more. If you want to know, you can go to the' Changbai' and' Baibai' knowledge bases, which have the most comprehensive CMS.

I hope my answer can help you a little.

PS: If you want to be a recruitment website, you need to find a recruitment website program. None of the above mentioned seems to have a recruitment function module.
