Example explanation of ThinkPHP+EasyUI

Assume that the fields of the accounting data table in the database are: id, code, name, islast. They are the auto-increment primary key, account code, account name, and whether it is the last-level account ("1" indicates the last-level account). Here, recursion is used in the model layer of Thinkphp to build the data required by ComboTree. The code and annotations are as follows:

 AccountModel   = ->field('id,code,name,islast')->(  & = (['code'( == 3['pid'] = 0['pid'] = (['code'],0,-2 ->createTree(  createSubTree(, = (  =>(['pid'] ==  = 'id' => ['id'],
                    'text'=>['name'],
                    'state'=>(['islast'] != 1)?'closed':'open'(['islast'] != 1 = ->createSubTree(,['code'(!(['children'] = (,   createTree( = (   => (['pid'] == 0 = 'id' => ['id'],
                    'text'=>['name'],
                    'state'=>'closed' = ->createSubTree(,['code'(!(['children'] = [] =

Data similar to the above (such as departments, regions, etc.) need to build a tree shape Similar functions can basically be achieved by simply modifying the menu code.
