数组内部的数组-按字母顺序排序

arrays inside array - sort alphabetically

本文关键字：数组顺序排序内部 | 更新日期: 2023-09-27

我有一个包含许多其他数组的数组。第一项是base64编码的字符串，第二项是实际字符串。

如何根据第二个字符串按字母顺序对数组进行排序？

            [1] => haine brigade - 10 - face � face  [www.pirate-punk.net].mp3
        )
)

在这个例子中，我需要根据以"kochise"或"haine brigade"

开头的字符串按字母顺序对子数组进行排序

此处：

function cmp($a, $b)
{
   return strcmp($a[1], $b[1]);
}
usort($your_data, "cmp");

function cmp($a, $b) {
    return strcmp($a[1], $b[1]);
}
usort($myArray, 'cmp');

    function aasort(&$yourarrayname, $key) { //this function will do this for you, just input the 
//array name and the  key name for this target array for the association
        $sorter=array(); //here we initialize the arrays to order or sort as you like
        $ret=array();
        reset($yourarrayname); //good code practices
        foreach ($array as $ii => $va) {      //loop through the array and sort each to each in this //new arrays
            $sorter[$ii]=$va[$key]; //storing 
        }
        asort($sorter, SORT_NATURAL | SORT_FLAG_CASE); //assort as alphabetic
        foreach ($sorter as $ii => $va) {
            $ret[$ii]=$array[$ii];
        }
        $array=$ret;
    }
      //call it like this
    aasort($your_array,"key");

解决此问题的简单方法是创建如下数组：这样做可以使用php排序函数。
