通過print_r遍歷亞馬遜購物API（大型多維數組）通過print_r

Question

遍歷API返回數組中的值總是有問題，通常是因爲它們非常複雜。無論如何，這一個讓我難住。

我不打算髮布整個陣列在這裏..但下面是它的要義。

爲了讓你知道，我試圖嵌套幾個foreach循環，但我得到了幾個錯誤，我無法想象有沒有更簡單的方法來做到這一點。

感謝您的幫助提前。

?> 

我試圖找回ItemAttributes->標題部分和DetailPageURL。期待聽取建議。

謝謝。

嘗試了這一點，我認爲它會做你想要什麼，雖然我沒有測試它

$amazon_array = $your_big_ass_amazon_array; // replace this with the array you show in your post 
$items = $your_big_ass_amazon_array['Items']; 
foreach($items as $item) { 
    $ItemAttributes = getSubArrayByIndex($item, 'ItemAttributes'); 
    $tittles[] = $ItemAttributes['title']; 
} 

print_r($titles); 

function getSubArrayByIndex($array, $index) { 
    if (!is_array($array)) return null; 
    if (isset($array[$index])) return $array[$index]; 
    foreach ($array as $item) { 
     $return = getSubArrayByIndex($item, $index); 
     if (!is_null($return)) { 
      return $return; 
     } 
    } 
    return null; 
}
