如果它是重复的，从数组中删除多维元素的值？

Question

我有一个像这样的多维数组

$input = Array
                      (
                          [222] => Array
                              (
                                  'id' => 222
                                  'val' => 'def'
                                  'more' => 'test'
                              ),
                        [223] => Array
                              (
                                  'id' => 223
                                  'val' => 'aaa'
                                  'more' => 'aaa'
                              ),
                        [224] => Array
                              (
                                  'id' => 224
                                  'val' => 'aaa'
                                  'more' => 'ddd'
                              )
                        [225] => Array
                              (
                                  'id' => 225
                                  'val' => 'def'
                                  'more' => 'test'
                              )
            );

*重复因为密钥val和more的值重复

我想删除重复值（在这种情况下是$ input [222]和$ input [225]。所以结果应该只

$res = Array
                      (
                          [222] => Array
                              (
                                  'id' => 222
                                  'val' => 'def'
                                  'more' => 'test'
                              ),
                        [223] => Array
                              (
                                  'id' => 223
                                  'val' => 'aaa'
                                  'more' => 'aaa'
                              ),
                        [224] => Array
                              (
                                  'id' => 224 
                                   'val' => 'aaa'
                                  'more' => 'ddd'
                              )
            );

任何人都知道怎么做？

Answer 1

$newInput = array();
 foreach($input as $k => $v) $newInput[$v['val'].$v['more']] = $v;
 //You may stop here. 
 $newInputNum = array();
 foreach($newInput as $k => $v) $newInputNum[$v['id']] = $v;

 echo "<pre>";print_r($newInputNum  );echo "</pre>";
