根据值从多维数组中删除元素

php arrays multidimensional-array

2022-08-30 11:00:36

我正在尝试根据值从多维数组中删除元素。在这种情况下，如果子数组的键“year”具有值2011，我希望该子数组出来。

只是为了记录：我正在运行PHP 5.2。

我的数组如下所示：

Array
(
    [0] => Array
        (
            [filmId] => 61359
            [url] => http://www.moviemeter.nl/film/61359
            [title] => Unstoppable
            [alternative_title] => 
            [year] => 2011
            [thumbnail] => http://www.moviemeter.nl/images/covers/thumbs/61000/61359.jpg

        )
    [1] => Array

        )
    [2] => Array
        (
            [filmId] => 68593
            [url] => http://www.moviemeter.nl/film/68593

        )
    [3] => Array
        (
            [filmId] => 17931
            [url] => http://www.moviemeter.nl/film/17931

            [votes_count] => 237
            [similarity] => 100.00
            [directors_text] => geregisseerd door David Carson
            [actors_text] => met Wesley Snipes, Jacqueline Obradors en Mark Sheppard

        )
)

答案 1

试试这个：

function removeElementWithValue($array, $key, $value){
     foreach($array as $subKey => $subArray){
          if($subArray[$key] == $value){
               unset($array[$subKey]);
          }
     }
     return $array;
}

然后你会这样称呼它：

$array = removeElementWithValue($array, "year", 2011);

答案 2

试试这个：

function remove_element_by_value($arr, $val) {
   $return = array(); 
   foreach($arr as $k => $v) {
      if(is_array($v)) {
         $return[$k] = remove_element_by_value($v, $val); //recursion
         continue;
      }
      if($v == $val) continue;
      $return[$k] = $v;
   }
   return $return;
}
