大神讲讲这个函数，无奈了

<?php
$arr1 = array(1,2,3,10,4);
$arr2 = array("a", "b", "c", "d");
array_multisort($arr1,$arr2);
print_r($arr1);
print_r($arr2);
?>
我觉得他应该输出
Array ( [0] => 1 [1] => 2 [2] => 3 [3]=> 4 [4] => 10 ) Array ( [0] => a [1]=> b [2] => c [3] => d )
啊他偏偏输出
Array ( [0] => 1 [1] => 2 [2] => 3 [3]=> 10 [4] => 4 ) Array ( [0] => a [1]=> b [2] => c [3] => d )…
