阅读list()函数,你可以在notes部分找到这样的警告：

Warning

list() assigns the values starting with the right-most parameter. If you are using plain variables,you don’t have to worry about this. But if you are using arrays with indices you usually expect the order of the indices in the array the same you wrote in the list() from left to right; which it isn’t. It’s assigned in the reverse order.

任何人都可以在反向订单分配时提供代码示例吗？

解决方法

php> $array = array();

php> list($array[0],$array[1]) = array(1,2)

php> var_dump($array)
array(2) {
  [1] =>
  int(2)
  [0] =>
  int(1)
}

因此[1]在[0]之前分配.
