An algorithm for calculating the actual price sometimes there is only one item in the ' Item_info_list ' sub-array ' coupon_detail_list ' sub-array there is only one offer information
And sometimes there is only one item in the ' Item_info_list ' sub-array ' coupon_detail_list ' subarray, there is no preferential information, sometimes ' item_info_list ' sub-array of only two items ' Coupon_detail_ There is only one preferential information in the list ' sub-array, sometimes there are only two items in the ' item_info_list ' sub-array ' coupon_detail_list ' sub-array there are two discount information, seeking the guidance of the Great God!




------Solution--------------------
What do you want to end up with?
------Solution--------------------
Just preprocess it.
foreach ($arr [' item_info_list '] as $v) $item _info_list[$v [' sku_id ']] = $v;
foreach ($arr [' coupon_detail_list '] as $v) $coupon _detail_list[$v [' sku_id ']] = $v;


foreach ($item _info_list as $k = $v)
echo "sku_id: $k Price:". Isset ($coupon _detail_list[$k])? $coupon _detail_list[$k] [' Coupon_price ']: $v [' Jd_price '], "
\ n ";

------Solution--------------------

PHP Code

foreach ($arr [' item_info_list '] as $key = + $val) {    if (isset ($arr [' coupon_detail_list '] [$key]))        $arr [' Item _info_list '] [$key] = Array_merge ($val, $arr [' coupon_detail_list '] [$key]);} Print_r ($arr);
