使用print_r($data)输出结果为 Array ( [0] => stdClass Object ( [color_item_no] => 1 [color_name] => sdf [size_item_no] => 1 [size] => S [jar_no] => 45 [qty] => 45 [stand_wgt] => [qty_unit] => 1 ) [1] => stdClass Object ( [color_item_no] => 1 [color_name] => sdf [size_item_no] => 2 [size] => M [jar_no] => 45 [qty] => 45 [stand_wgt] => [qty_unit] => 1 ) )
这种情况下一般使用任何框架原本的输出方法可能都会出错,比如laravel框架中 echo $data[0]['qty'];会报stdClass Object这个问题,那么这个时候就$data[0]->qty就可以了。
