Php 从排序数组中重新运行键的顺序

我在PHP中有这样一个数组

$somevar = array(1, 5, 2, 7, 17, 2, 13);

我想对数组进行排序，但不移动值，因此我得到另一个具有索引/键顺序的数组

因此，我的新阵列将类似于

{0, 2, 5, 1, 3, 6, 4}

键的顺序是什么？这应该适合您：

<?php

    $somevar = array(1, 5, 2, 7, 17, 2, 13);
    $newArray = array_values($somevar);
    asort($newArray);
    $newArray = array_keys($newArray);
    print_r($newArray);

?>

试试这个..

$somevar = array(1, 5, 2, 7, 17, 2, 13);
print_r($somevar);
//your array
Array ( [0] => 1 [1] => 5 [2] => 2 [3] => 7 [4] => 17 [5] => 2 [6] => 13 )
asort($somevar);
print_r($somevar);
//After sort
Array ( [0] => 1 [2] => 2 [5] => 2 [1] => 5 [3] => 7 [6] => 13 [4] => 17 ) 
print_r(array_keys($somevar));
//array key sorted array
Array ( [0] => 0 [1] => 2 [2] => 5 [3] => 1 [4] => 3 [5] => 6 [6] => 4 )

是的，我已经看过了，我也看过PHP排序函数，但是找不到任何东西，但是没有移动OP周围的值。我不想更改原始数组@我只是做了一些解释

$somevar = array(1, 5, 2, 7, 17, 2, 13);
print_r($somevar);
//your array
Array ( [0] => 1 [1] => 5 [2] => 2 [3] => 7 [4] => 17 [5] => 2 [6] => 13 )
asort($somevar);
print_r($somevar);
//After sort
Array ( [0] => 1 [2] => 2 [5] => 2 [1] => 5 [3] => 7 [6] => 13 [4] => 17 ) 
print_r(array_keys($somevar));
//array key sorted array
Array ( [0] => 0 [1] => 2 [2] => 5 [3] => 1 [4] => 3 [5] => 6 [6] => 4 )
