從多維數組比索

Question

獲取值我有一個產品陣列（每個產品都有多個陣列）

我想要得到的值[「0_1」]或[「0_2」]？ 如果以0開始，應該該產品發送到陣列

array(14) { 
    ["0_1"]=> array(27) { 
     ["files"]=> array(0) { } 
     ["images"]=> array(0) { }

那些在左側（例如，「0_1」）的端部是數組鍵，和值是在右側的人。

得到公正的鑰匙，使用：

$arrayOfKeys = array_keys($array) 

或遍歷每個項目，使用：

foreach ($array as $key => $value) { }
