array_multisort seems to ignore natural sort

本文关键字：自然排序 multisort array | 更新日期: 2023-09-27

我正在使用PHP 5.6.6，并且在array_multisort中遇到NATURAL_SORT问题。

如果我这样做：

sort($var);

我得到正确的"自然"输出，例如

p0_00001
p0_00002_
p0_00002_00011
p0_00002_00012
p0_00002_00013
p0_00002_00014
p0_00003_
p0_00003_00015
p0_00003_00016
p0_00003_00017
p0_00003_00018
p0_00003_00019
p0_00003_00020
p0_00003_00021
p0_00003_00022
p0_00003_00023
p0_00003_00024
p0_00004_
p0_00004_00025

有了array_multisort，我就这样坚持了下来：

array_multisort($var, $foo, $bar)

这给了我：

p0_00001
p0_00002_
p0_00003_
p0_00004_
p0_00005_
p0_00006_
p0_00007_
p0_00008_
p0_00009_
p0_00010_
p0_00002_00011
p0_00002_00012
p0_00002_00013
p0_00002_00014
p0_00003_00015
p0_00003_00016
p0_00003_00017
p0_00003_00018
p0_00003_00019
p0_00003_00020
p0_00003_00021
p0_00003_00022
p0_00003_00023
p0_00003_00024

我试过了

  array_multisort($var, SORT_NATURAL, $foo, $bar)

但输出保持不变。我不明白如何用户array_multisort以获得sort($var)的"自然"输出

试试这个：

array_multisort ($var, SORT_ASC, SORT_REGULAR,
                 $var2, SORT_ASC, SORT_REGULAR,...);

哪个$var, $var1, $var2...是要排序的数组
注意：这些数组是通过引用传递的

试试这个

$dataPoints1 = array('p0_00201','p3_00002_','p2_00002_00011','p0_00022_00012','p0_00002_00013','p0_00002_00014','p0_00003_');
    echo "<pre>";
    print_r($dataPoints1);
    array_multisort($dataPoints1);
    echo "<pre>";
    print_r($dataPoints1);
