Hello,

I need some help on include an php file in model.

I had use builder to create a model & class call "Ctbc" , I wish to include a php file into this model so I can use the API function

my model path : plugins/author/ctbc/models/Ctbc.php

my api.php path : plugins/author/ctbc/models/vendors/api.php

Please help Thank you

Look into PHP namespacing, you'll need to understand that and composer autoloading of classes to figure out how to properly use the use statements at the top of the file.
