SELECT tbl_stock.* , series.*, series_size.*, tbl_size.* FROM
tbl_stock , series, series_size, tbl_size
WHERE
tbl_stock.series_id = series.series_id AND
tbl_stock.size_id = series_size.size_id AND

I have Tried DB Query builder laravel but getting exception
$stock_info = DB::table(['tbl_stock', 'shades'])->get();

First of all, you should replace your archaic join syntax with modern syntax:
SELECT
t1.*,
t2.*,
t3.*,
t4.*
FROM tbl_stock t1
INNER JOIN series t2
ON t1.series_id = t2.series_id
INNER JOIN series_size t3
ON t1.size_id = t3.size_id
INNER JOIN tbl_size t4
ON t1.size_id = t4.size_id;
Then, use Laravel's query builder syntax to build your query in PHP code:
$stocks = DB::table('tbl_stock')
->join('series', 'tbl_stock.series_id', '=', 'series.series_id')
->join('series_size', 'tbl_stock.size_id', '=', 'series_size.size_id')
->join('tbl_size', 'tbl_stock.size_id', '=', 'tbl_size.size_id')
->select('tbl_stock.*', 'series.*', 'series_size.*', 'tbl_size.*')
->get();
