的foreach未定义指数

上午通过阵列试图循环，与print_r我得到下面的数组，但我得到的foreach未定义指数

“通知：未定义指数：名称”

错误，当我跑我的循环，不知道做错了什么？请帮助

     [17] => Array

     [18] => Array

     [19] => Array 
      (

       [name] => Paul 
       [email] => [email protected] 
      ) 

    ) 

)

我的PHP循环低于

foreach ($retr as $page) { 
     echo $page['name']; 
     //var_dump($page); 
    }

问候

是什么'的var_dump（$页）的结果;'？ – Loko

你有一个多维数组，你可能需要循环'$ retr [0]'，或者有第二个'foreach'循环遍历第一级。 –

你的阵列是多维，是含有19种进一步的子元素的单一元素数组。

如果你只是想itterate子元素，然后跑过来顶层elelemt，不是父阵列循环：

foreach ($retr[0] as $page) {...}
