要素の増分に従って、[partyplan_select_products]の数を取得する必要があります。

Answer 1

これは、再帰的な配列の列関数である

function array_column_recursive(array $haystack, $needle) { 
    $found = []; 
    array_walk_recursive($haystack, function($value, $key) use (&$found, $needle) { 
     if ($key == $needle) 
      $found[] = $value; 
    }); 
    return $found; 
} 

、これを試してみてください。あなたの配列に表示されているようなランダムなキーは考慮されません。その後 、

あなたが得る、

$sum_arr = array_column_recursive($your_arr, 'partyplan_select_products'); 

そして最後に合計数を取得するには、 あなたはarray_sum機能を使用することができます。

$count = array_sum($sum_arr); 

これがあなたに役立つことを願っています。
