Php: getting all sub-classes under different categories _ PHP Tutorial

Php obtains all subclass methods under different categories. Php obtains all subclass methods under a category to obtain all subclass methods under a category: staticfunctiongetMenuTree ($ arrCat, $ parent_id0, $ level0, $ allTrue) {static $ arrTree; php retrieves all subclass methods under a category

Obtain all sub-classes of a category:

Static function getMenuTree ($ arrCat, $ parent_id = 0, $ level = 0, $ all = True)

{

Static $ arrTree; // use static instead of global

If (! $ All) $ arrTree = '';

If (empty ($ arrCat) return FALSE;

$ Level ++;

If ($ level = 1) $ arrTree [] = $ parent_id;

Foreach ($ arrCat as $ key => $ value)

{

If ($ value ['parent _ Cid'] = $ parent_id)

{

// $ Value ['level'] = $ level;

$ ArrTree [] = $ value ['CID'];

Unset ($ arrCat [$ key]); // deregister the data of the current node to reduce useless traversal

Self: getMenuTree ($ arrCat, $ value ['CID'], $ level );

}

}

Return $ arrTree;

}

The premise of using this method is to write the classification to the cache file. the write method of the cache file is as follows:

Public function actionIndex2 ()

{

$ Filepath = Yii: getPathOfAlias ('application'). '/data /';

$ Arr = array ();

$ Db = Yii: app ()-> db;

$ Listinfo = $ db-> createCommand ("select name, cid, parent_cid, root_cid from item_cat_info")-> queryAll ();

Foreach ($ listinfo as $ val)

{

$ Arr [$ val ['CID'] = array ('CID' => $ val ['CID'], 'name' => $ val ['name'], 'parent _ Cid' => $ val ['parent _ Cid'], 'root _ Cid' => $ val ['root _ Cid']);

}

$ Applist = "";

File_put_contents ($ filepath. 'itemcat. php', $ applist );

}
