Php 按多个字段对多维数组排序

我有以下数据：

Array ( 
  [0] => Array ( 
         [filename] => def
         [filesize] => 4096 
         [filemtime] => 1264683091 
         [is_dir] => 1 
         [is_file] => 
  ) 
  [1] => Array ( 
         [filename] => abc
         [filesize] => 4096 
         [filemtime] => 1264683091 
         [is_dir] => 1 
         [is_file] => 
  ) 
  [2] => Array ( 
         [filename] => rabbit
         [filesize] => 4096 
         [filemtime] => 1264683060 
         [is_dir] => 0
         [is_file] => 
  )
  [3] => Array ( 
         [filename] => owl
         [filesize] => 4096 
         [filemtime] => 1264683022
         [is_dir] => 0
         [is_file] => 
  )
)

我想按不止一个值对它进行排序。（例如，按is_dir和文件名（按字母顺序）或按filemtime和文件名等）

到目前为止，我已经尝试了很多解决方案，但没有一个有效

有人知道最好的PHP算法/函数/方法来对其进行排序吗？

使用并将您自己的比较函数传递给该函数

//example comparison function
//this results in a list sorted first by is_dir and then by file name
function cmp($a, $b){
    //first check to see if is_dir is the same, which means we can
    //sort by another factor we defined (in this case, filename)
    if ( $a['is_dir'] == $b['is_dir'] ){
        //compares by filename
        return strcmp($a['filename'], $b['filename']);
    }
    //otherwise compare by is_dir, because they are not the same and
    //is_dir takes priority over filename
    return ($a['is_dir'] < $b['is_dir']) ? -1 : 1;   
}

    //sort by another factor we defined (in this case, filename)
    if ( $a['is_dir'] == $b['is_dir'] ){
        //compares by filename
        return strcmp($a['filename'], $b['filename']);
    }
    //otherwise compare by is_dir, because they are not the same and
    //is_dir takes priority over filename
    return ($a['is_dir'] < $b['is_dir']) ? -1 : 1;   
}

是对多个或多维数组进行排序的特殊函数。我曾经使用过它，并且很喜欢。

谢谢。我想我以前试过，但显然不行，因为它奏效了。谢谢。我想我以前试过，但显然不行，因为它奏效了。
