Discuz x2.5 in the database read exception, ask the hero pointing

Discuz x2.5 Database read error, ask the hero pointing!
The code in bargai_indexphp in Source\module\bargai is:
$sql _store = ' SELECT cate_name from Ecm_scategory ORDER by Sort_order ';
$my _category= implode (", Db::fetch_all ($sql _store));

The code in bargai_index.html in Template\default\bargai is:







The display in IE can be:
Array, array, array, array, array, array, array, array, array, array, array, array.
Why can't I output the data in Cate_name--the name of the product?


------to solve the idea----------------------
Implode only one-dimensional arrays can be concatenated into strings
Your db::fetch_all apparently returned a two-dimensional array.
To write like this

$my _category = Implode (", Array_map (' Implode ', Db::fetch_all ($sql _store)));

------to solve the idea----------------------

foreach (Db::fetch_all ($sql _store) as $row) {
  echo $row [' Cate_name ']. '
';
}
