Как добавить ключевое значение многомерного массива в другой массив

Question

Моя проблема заключается в том, что мне нужно извлечь только одно поле из массива, а затем сохранить в другом массиве.

коды:

$obj = json_decode($event,true); 

[данные] => массив (

[0] => Array 
(
    [metadata] => Array 
     (

Я попытался извлечь резюме из массива и хранить его в другом массиве:

$count=0; 
$newArray = array(); 
foreach($obj as $row) 
{ 
    $newArray[] = array('summary' => $row); 
    $new=$newArray[$count]['summary'][$count]['metadata']['summary']; 
    $count++; 
} 

Это то, что я пытаясь достичь в конце концов:

data=> Array 
    (
     [0] => Array 
      (
       [metadata] => Array 
        (

Проблема им перед им не в состоянии извлечь всю сводку из массива из моего кода я извлекаться только первый индекс массива.

Я попытался получить данные, увеличив счет, хотя он не работает.

Answer 1

Просто предназначаться соответствующие данные, которые вы хотите, то так как они имеют ту же структуру, это будет то же самое на другой:

$new['data'] = array(); 
foreach($obj['data'] as $values) { 
    $new['data'][]['metadata']['summary'] = $values['metadata']['summary']; 
    //^new assignment 
} 

echo '<pre>'; 
print_r($new); 

В качестве альтернативы, если вы не хотите, новую копию, вы также можете поместить ссылку на каждую копию внутри foreach и сделать unset() по тем индексам, которые вы не хотите.

foreach($obj['data'] as &$values) { 
    unset($values['metadata']['name'], $values['metadata']['publicProfileUrl']); 
}
