通過數組的數組

我目前有以下陣列工作循環，通過數組的數組

Array 
(
    [0] => Array 
     (
      [0] => Array 
       (
        [candidate_id] => 41

       ) 

     ) 

    [1] => Array

       ) 

     )

，你可以看到它是一個數組類型的情況中的數組，我想遍歷它拉出來在first_name + surname每個條目的，但我得到以下錯誤，當我嘗試這樣做，

A PHP Error was encountered 

Severity: Notice 

Message: Undefined index: firstname 

Filename: admin/candidate_list.php 

Line Number: 5

我通過它循環這樣的時刻，

<?php foreach ($candidates as $k => $v) : ?> 
    <li><a href="<?php echo site_url(); ?>candidates/card/id/<?php echo $v['id']; ?>"><?php echo $v[0]['first_name']. " ".$v[0]['surname']; ?></a></li>

我在做什麼錯？

你需要的是嵌套循環。循環內循環 – Ibu

你確定你的代碼是最新的嗎？根據你想要訪問'$ v ['firstname']'而不是'$ v ['first_name']'的錯誤。 –

@ sico87：很難從您提供的代碼中分辨出來。你能告訴我們你如何定義'候選人'嗎？ –

這會給你什麼？

<?php foreach ($candidates as $k => $v) print_r($v); ?>

我不知道如何$ V [「身份證」]將被定義既考慮到陣列，所以有別的東西，你要離開了......

而且你使用SITE_URL （）...我聞到CodeIgniter的味道嗎？ ;）

你的數組對於那個循環來說太深了。我假設$candidates是整個陣列的名字？你並不需要每個候選人都在他們自己的陣列中，試着讓你的結果放在一個低一級的數組中，並且foreach可以工作。

<? 
    for($i=0; $i=50; $i++){ 
    foreach ($candidates[$i] as $v){ 
    ?> 
     <li><a href="<?php echo site_url(); ?>candidates/card/id/<?php echo $v[0]['candidate_id']; ?>"><?php echo $v[0]['first_name']. " ".$v[0]['surname']; ?></a></li> 
    <? 
    } 
    } 
?>

'$ i => 0'？咦？ –

哎呀，對不起大聲笑 –

'$ i = 50'？咦？（嘻嘻） –
