call_user_func_array 和 array_multisort 排序问题

[橙风子]

$array = [
		['a'=>1, 'b'=>'1', 'c'=>'scdn'],
		['a'=>2, 'b'=>'2', 'c'=>'scdn'],
		['a'=>3, 'b'=>'3', 'c'=>'scdn'],
		['a'=>4, 'b'=>'4', 'c'=>'scdn'],
		['a'=>5, 'b'=>'5', 'c'=>'scdn'],
		['a'=>6, 'b'=>'6', 'c'=>'scdn'],
		['a'=>7, 'b'=>'7', 'c'=>'scdn'],
		['a'=>9, 'b'=>'8', 'c'=>'scdn'],
		['a'=>9, 'b'=>'9', 'c'=>'scdn'],
		['a'=>10, 'b'=>'10', 'c'=>'scdn'],
];
$asc  = SORT_ASC;
$desc = SORT_DESC;
$array = [array_column($array, 'a'), $desc, $array];
array_multisort($array[0], $array[1], $array[2]);
//call_user_func_array('array_multisort', $array);
print_r($array[2]);

array_multisort($array[0], $array[1], $array[2]); 正常运行排序
call_user_func_array('array_multisort', $array); 无法排序呢，求解

[xuzuning]

$desc = SORT_DESC;
$ar = [array_column($array, 'a'), $desc, &$array];
call_user_func_array('array_multisort', $ar);
print_r($ar[2]);

1、array_multisort 是对数组的引用进行排序的 2、由于是传递引用，所以数组要改名 慢慢体会吧
