的foreach未定義指數

上午通過陣列試圖循環，與print_r我得到下面的數組，但我得到的foreach未定義指數

「通知：未定義指數：名稱」

錯誤，當我跑我的循環，不知道做錯了什麼？請幫助

Array

     [19] => Array 
      (

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

    ) 

)

我的PHP循環低於

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

問候

是什麼'的var_dump（$頁）的結果;'？ – Loko

你有一個多維數組，你可能需要循環'$ retr [0]'，或者有第二個'foreach'循環遍歷第一級。 –

你的陣列是多維，是含有19種進一步的子元素的單一元素數組。

如果你只是想itterate子元素，然後跑過來頂層elelemt，不是父陣列循環：

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