PHP array sorting can be implemented using the array_multisort method, but if it is a multi-dimensional array and we want to specify a field in the array for sorting, then we need to write our own method to implement it. This article shares a piece of code for the multi-dimensional array sorting method of specified fields in PHP. This code can sort the array according to the field field.

function sortArrByField(&$array, $field, $desc = false){
  $fieldArr = array();
  foreach ($array as $k => $v) {
    $fieldArr[$k] = $v[$field];
  }
  $sort = $desc == false ? SORT_ASC : SORT_DESC;
  array_multisort($fieldArr, $sort, $array);
}

The above is the multi-dimensional array sorting method of PHP specified fields. I hope this PHP code will help you.

The above introduces the multi-dimensional array sorting method of PHP specified fields, including sorting methods and PHP content. I hope it will be helpful to friends who are interested in PHP tutorials.
