我只想得到這個值：決策分析，市場營銷，控制和信息政策，財務管理，「。運營管理，人事管理，企業的家庭，經濟，政治和社會環境，人的因素，企業的政策

我的意思是裏面areas-academicas

我使用嵌套的foreach，但沒有：

foreach ($un as $key => $value) 
    { 

     if ($key === "areas-academicas") 
     { 
     echo "Llave: " . $key . " => "; 
     //echo $value; 
     foreach ($value as $key2 => $value2) 
     { 
      echo "Llave2: " . $key2 . "<br />" . "valor2: " . $value2; 

      foreach ($value2 as $key3 => $value3) 
      { 
      echo "Llave3: " . $key3 . "<br />" . "valor3: " . $value3; 
      } 
     } 
     } 

    }

，這可能是一個簡單的方法來獲得這些價值？謝謝。

array_walk_recursive – bxN5

要誠實，你有一個壞的數據結構，這將是更好的，如果因此它是一個有點更容易得到處理，你可以重新設計它。是 –

如果我不搞砸你的嵌套隨着這應該工作。如果不能解決只是foreach內的路徑。

$data = array(...); // the array you posted 

foreach ($data["areas-academicas"]["data"]["options"] as $area) { 
    echo $area["title"]; 
}

底線是，你可以從任何級別開始迭代，你不必在上面一定要開始。

這對我的作品，謝謝。 – user2580401

在陣列看，似乎你只能在兩個數組在頂層興趣：

$un["areas-academicas"] 
$un["areas-academicas-2"]

然後你正在尋找特定值，數據的選擇稱號，在嵌套結構這兩個下：

$un["areas-academicas"]['data']['options'][....]['title']

您可以通過使用這些陣列的均勻結構可能限制你的循環迭代。但我會假設你通過頂層陣列希望環路包含「領域學術」鍵：

$titles = array(); 
foreach ($un as $key => $value){ 
    if(strpos($key, 'areas-academicas') == false){ continue; } 
    foreach($value['data']['options'] as $val){ 
     $titles[] = $val['title']; 
    } 
}

這個循環應該收集領域學術陣列中的所有選項的標題，但概念是，依賴嵌套結構將統一爲頂級陣列中的關鍵領域學術的每個實例。希望這有助於
