如何向多维数组添加值？

Question

I compare these two arrays:

$array1:

   array(3) {
          [0]=>
          array(10000) {
            ["12345"]=>
            array(5) {
              ["dateTime"]=>
              string(19) "2016-10-12 19:46:25"
              ["fileName"]=>
              string(46) "monkey.jpg"
              ["path"]=>
              string(149) "Volumes/animals/monkey.jpg"

我将它们与此功能进行比较：

    function array_diff_assoc_recursive($array1, $array2){
                    foreach($array1 as $key => $value){
                        if(is_array($value)){
                            if(!isset($array2[$key])){
                                $difference[$key] = $value;
                            }
                            elseif(!is_array($array2[$key])){
                                $difference[$key] = $value;
                            }
                            else{
                                $new_diff = array_diff_assoc_recursive($value, $array2[$key]);
                                if($new_diff != FALSE)
                                {
                                    $difference[$key] = $new_diff;
                                }
                            }
                        }
                        elseif(!isset($array2[$key]) || $array2[$key] != $value){
                            $difference[$key] = $value;
                        }
                    }
                    return !isset($difference) ? 0 : $difference;
                }


                echo "<pre>";
                print_r(array_diff_assoc_recursive($array1, $array2));
                echo "</pre>";

结果是：

array(1) {
  [0]=>
  array(1) {
    ["12345"]=>
    array(1) {
      ["fileName"]=>
      string(46) "monkey.jpg"
    }
  }
}

但我需要的是，无论差异在哪里，我也总是需要路径在数组中。我试图将 $value["path"] 添加到数组 $difference 但不知道该怎么做。

我需要的结果是：

 array(1) {
      [0]=>
      array(1) {
        ["12345"]=>
        array(2) {
          ["fileName"]=>
          string(46) "monkey.jpg"
          ["path"]=>
          string(46) "Volumes/animals/monkey.jpg"
        }
      }
    }

Answer 1

试试这个

function array_diff_assoc_recursive($array1, $array2){
                    foreach($array1 as $key => $value){
                        if(is_array($value)){
                            if(!isset($array2[$key])){
                                $difference[$key] = $value;
                                $difference['path'] = $value['path'];
                            }
                            elseif(!is_array($array2[$key])){
                                $difference[$key] = $value;
                                $difference['path'] = $value['path'];
                            }
                            else{
                                $new_diff = array_diff_assoc_recursive($value, $array2[$key]);
                                if($new_diff != FALSE)
                                {
                                    $difference[$key] = $new_diff;
                                    $difference['path'] = $new_diff['path'];
                                }
                            }
                        }
                        elseif(!isset($array2[$key]) || $array2[$key] != $value){
                            $difference[$key] = $value;
                        }
                    }
                    return !isset($difference) ? 0 : $difference;
                }


                echo "<pre>";
                print_r(array_diff_assoc_recursive($array1, $array2));
                echo "</pre>";

我已经更改了您的功能，现在它可以正常工作了：

efunction array_diff_assoc_recursive($array1, $array2){
foreach($array1 as $key => $value){
    if(is_array($value)){
        if(!isset($array2[$key])){
            $difference[$key] = $value;
        }
        elseif(!is_array($array2[$key])){
            $difference[$key] = $value;
        }
        else{
            $new_diff = array_diff_assoc_recursive($value, $array2[$key]);
            if($new_diff != FALSE)
            {
                $difference[$key] = $new_diff;
            }
        }
    }
    elseif(!isset($array2[$key]) || $array2[$key] != $value){
        $difference[$key] = $value;
        $difference['path'] = $array1['path']; // added this feature here
    }
}
return !isset($difference) ? 0 : $difference;

}
