【问题描述】：

我有图像数组，例如

    [Images] => Array
        (
            [0] => /var/www/httpdocs/images/products/detail/10396-alt-1.jpg
            [1] => /var/www/httpdocs/images/products/detail/10396-main-599.jpg
        )

    [Images] => Array
        (
            [0] => /var/www/httpdocs/images/products/category/10167-main-354.jpg
            [1] => /var/www/httpdocs/images/products/detail/10167-alt-1.jpg
            [2] => /var/www/httpdocs/images/products/detail/10167-alt-2.jpg
            [3] => /var/www/httpdocs/images/products/category/10168-main-361.jpg
            [4] => /var/www/httpdocs/images/products/category/10168-main-360.jpg
        )

我想按基本名称排序，但也按字母数字以特定方式排序

我总是希望前 5 位数字在 alpha 升序排序 (z-a) 后按数字排序，然后最后一位数字降序排序。我将如何做到这一点？

示例输出应该是这样的

    [Images] => Array
        (
            [0] => /var/www/httpdocs/images/products/detail/10396-main-599.jpg
            [1] => /var/www/httpdocs/images/products/detail/10396-alt-1.jpg
        )

    [Images] => Array
        (
            [0] => /var/www/httpdocs/images/products/category/10167-main-354.jpg
            [1] => /var/www/httpdocs/images/products/category/10168-main-360.jpg
            [2] => /var/www/httpdocs/images/products/category/10168-main-361.jpg
            [3] => /var/www/httpdocs/images/products/detail/10167-alt-1.jpg
            [4] => /var/www/httpdocs/images/products/detail/10167-alt-2.jpg
        )

【问题讨论】：

你能提供一个想要的结果的例子吗？
是的，等一下，我会提供结果和更深入的数组

标签： php sorting

【解决方案1】：

从路径中提取文件名：10396-main-599
用'-'作为分隔符分割文件名10396,main,599

使用比较函数对路径进行排序

function is_path_less($split_path1,$split_path2){
  if($split_path1[0] == $split_path2[0]){
    if($split_path1[1] == $split_path2[1]){
      return $split_path1[2] < $split_path2[2];
    }else{
      return $split_path1[1] > $split_path2[1];
    }
  }else{
    return $split_path1[0] < $split_path2[0];
  }
}

其中$split_path1 和 $split_path2 是 ["10396","main","599"] 和 ["10396","alt","1"]

结果将是：

["10396","main","599"]
["10396","alt","1"]
