tp 用group去重

$baseGoodIds_arr = [1,2,3,4,5,6,7,8,9];
$relate_gimgs = D('GoodsImages')->where(['good_id' => ['in',$baseGoodIds_arr]])->limit($gimgs_limit)->group('weight')->select();
dump($relate_gimgs);

weight 字段去重复

array(4) {

  [0] => array(5) {

    ["id"] => string(2) "12"

    ["good_id"] => string(1) "7"

    ["resource_name"] => string(23) "1536291421397879873.png"

    ["weight"] => string(1) "0"

    ["create_time"] => string(10) "1536291421"

  }

  [1] => array(5) {

    ["id"] => string(1) "1"

    ["good_id"] => string(1) "1"

    ["resource_name"] => string(22) "153628483559948187.png"

    ["weight"] => string(1) "1"

    ["create_time"] => string(10) "1536284870"

  }

  [2] => array(5) {

    ["id"] => string(2) "13"

    ["good_id"] => string(1) "8"

    ["resource_name"] => string(24) "15362918002142249103.png"

    ["weight"] => string(7) "136155

"

    ["create_time"] => string(10) "1536291800"

  }

  [3] => array(5) {

    ["id"] => string(1) "8"

    ["good_id"] => string(1) "6"

    ["resource_name"] => string(24) "15362922181586297198.png"

    ["weight"] => string(7) "194794

"

    ["create_time"] => string(10) "1536292218"

  }

}
