問題描述

$allPackGoods = array(

['id'=>1,'stock'=>14,'num'=>6],

['id'=>2,'stock'=>20,'num'=>6],

['id'=>3,'stock'=>20,'num'=>6],

['id'=>4,'stock'=>18,'num'=>6],

['id'=>5,'stock'=>54,'num'=>6]

);

按照件數去生成數組直到把庫存都清空掉

最終結果類似

[[{"id":1,"stock":8,"num":6,"use":6},{"id":2,"stock":14,"num":6,"use":6},{"id":3,"stock":14,"num":6,"use":6}],[{"id":1,"stock":2,"num":6,"use":6},{"id":2,"stock":2,"num":6,"use":6},{"id":4,"stock":12,"num":6,"use":6}]]

但是組合里面不能有相同的id，代碼應該如何實現？在線等，求大神解救

問題解答

補充一下：這里類似是生成組合 每個組合下面可以有多個商品 商品數量可以定義例如 1-3個 2-3個
