面對錯誤

Question

我的控制器功能是

public function listAction() 
{ 
     $params = array('host'  =>'localhost', 
         'username' =>'root', 
         'password' =>'', 
         'dbname' =>'zend' 
         ); 
     $DB = new Zend_Db_Adapter_Pdo_Mysql($params); 
     $DB->setFetchMode(Zend_Db::FETCH_OBJ); 
     $sql = "SELECT * FROM `user` ORDER BY user_name ASC"; 
     $result = $DB->fetchAssoc($sql); 
     echo count($result); 
     $this->view->assign('title','Member List'); 
     $this->view->assign('description','Below, our members:'); 
     $this->view->assign('datas',$result); 
} 

和PHTML文件由

<?php 
$datas = $this->datas; 
    for($i = 1; $i<= count($datas);$i++) 
    { echo $datas[$i]['id']; 
    echo $datas[$i]['user_name']; 
    echo $datas[$i]['first_name']; 
    echo $datas[$i]['last_name']; 
     } ?> 

取MySQL表它顯示錯誤中的未定義的偏移量= 1，如果我啓動for循環從2它是好的，並顯示一個較少的行形式的MySQL表。

請幫幫忙，我沒有得到在錯誤

因爲$ DATAS不具有1數組索引用下面的代碼替換您的PHTML文件。希望這會有所幫助。

<?php 
$datas = $this->datas; 
foreach ($datas as $data) { 
    echo $data['id']; 
    echo $data['user_name']; 
    echo $data['first_name']; 
    echo $data['last_name']; 
} 
?>
