PHP method to implement two-dimensional array sorting by a certain column

The example in this article describes the method of sorting a two-dimensional array by a certain column in PHP. Share it with everyone for your reference, the details are as follows:

/*
* 二维数组 按某列排序
* array_multisort($arr1,$arr2)
* 手册 例子如下
*
*/
$data[] = array('volume' => 67, 'edition' => 2);
$data[] = array('volume' => 86, 'edition' => 1);
$data[] = array('volume' => 85, 'edition' => 6);
$data[] = array('volume' => 98, 'edition' => 2);
$data[] = array('volume' => 86, 'edition' => 6);
$data[] = array('volume' => 67, 'edition' => 7);
// 取得列的列表
foreach ($data as $key => $row) {
  $volume[$key] = $row['volume'];
  $edition[$key] = $row['edition'];
}
// 将数据根据 volume 降序排列，根据 edition 升序排列
// 把 $data 作为最后一个参数，以通用键排序
array_multisort($volume, SORT_DESC, $edition, SORT_ASC, $data);
/*************************************/
/* 从上面的例子不难看出，array_multisort()函数
* 是将每一个二维数组的列作为 一个参数进行排序
* 来达到整个数组的排序
*/
/*************************************/
function sigcol_arrsort($data,$col,$type=SORT_DESC){
  if(is_array($data)){
    $i=0;
    foreach($data as $k=>$v){
      if(key_exists($col,$v)){
        $arr[$i] = $v[$col];
        $i++;
      }else{
        continue;
      }
    }
  }else{
    return false;
  }
  array_multisort($arr,$type,$data);
  return $data;
}
print_r(sigcol_arrsort($data,'edition',SORT_DESC));
/*说白了 原理就是：
新数组  原二维数组
 2    array('volume' => 67, 'edition' => 2);
 1    array('volume' => 86, 'edition' => 1);
 6    array('volume' => 85, 'edition' => 6);
 2    array('volume' => 98, 'edition' => 2);
 6    array('volume' => 86, 'edition' => 6);
 7    array('volume' => 67, 'edition' => 7);
这两个数组的每一行都锁在一起，新数组一旦变动顺序，
那么就会连带每一行的二维数组也跟着变换顺序 ，即新数组为参照物
相当于查询子句中的 order by
