如何对数组中的值进行排序[重复]

$my_array_to_sort=[['id'=>19381881,'value'=>4],['id'=>19970711,'value'=>65],['id'=>19231029,'value'=>18]];

How can I sort this array to get an array like this ?

(sort by 'value',high to low );

  $my_sorted_array=[
                      ['id'=>19970711,'value'=>65], 
                      ['id'=>19231029,'value'=>18],
                      ['id'=>19381881,'value'=>4],
                     ];

</div>

I made this function to sort every multidimensional array by one of it's columns :

function sortArrayBy($array , $column_name,$sort=SORT_DESC){
  foreach ($array as $key => $row) {
   $column[$key]  = $row[$column_name];
  }
  array_multisort($column, $sort, $array);
  return $array;
 }

Call it like this :

<?php  $my_sorted_array = sortArrayBy($my_array_to_sort,'value') ; ?>
