大神求助 急...
两个二维数组
$cart = arrray(array("id"=1,"num="2"));(session中的array值)
第一次传 $newcart = arrray(array("id"=1,"num="4");array("id"=2,"num="4"))
第二次传 $newcart = arrray(array("id"=9,"num="4");array("id"=1,"num="5"))
第三次传 id 是随时变的....
。。。。。
怎么样遍历 使它变成 $cart = arrray(
[0]=>array("id"=>1,"num"=>10)
[1]=>array("id"=>2,"num"=>4)
[2]=>array("id"=>9,"num"=>5)
)
怎么就实现 大神求助啊
------解决方案--------------------
没看懂,id为9 的num怎么变成5了。id=1 的也不知道怎么来的。

做购物车最好是用 id作为数组的key,这样对于添加修改删除操作都狠方便。
符号要注意一下 数组指向值是"=>" ,不是"="。
