DZ Forum core code analysis plan - core file common.inc.php_PHP tutorial
Previous article: DZ Forum core code analysis - core file global.func.php
This file is the core brain-level file of DZ.
In actual analysis, there is not much content. Most of them are conditional judgments and command statements. Introducing a large number of files.
Understanding this file can better understand how the entire DZ forum operates. This file is introduced on almost every page.
To be honest, the farther back I look, the bigger my head gets. . . A large number of multi-layer 3D conditional judgments. . Hehe, I don’t know if I’m right, it’s this type. Some are inlaid with as many as 4 layers. Feeling dizzy. But it's mostly done.
The most worth learning about this document is its emphasis on and handling of security. .
Upload the file with the comments first
The other files will be sorted and sent up later. But this is enough to explain a lot of things.
I hope you experts can point out any mistakes in writing.
Originally, I planned to finish this part and then post it in an update. but. . . In the afternoon, I was confused when analyzing the code of DZ's caching mechanism. Just go get SVN. SVN downloads are now available.
Why is this floor updated but not downloaded? It's because this part hasn't been completed yet. There are 3 files analyzed today in SVN for reference
