沒有數據庫顯示

在這裏我有我的代碼，當我測試了一切工作正常工作，沒有顯示MySQL連接的結果。我嘗試了不同的東西，但似乎沒有工作。我希望這裏的某個人能夠找到並指出導致此數據庫無法工作的問題在哪裏。沒有數據庫顯示

這裏是我的代碼

請[停止使用'mysql_ *'函數]（http://stackoverflow.com/questions/12859942/why-shouldnt-i-use-mysql-functions-in-php）。他們不再被維護，並[正式棄用]（https://wiki.php.net/rfc/mysql_deprecation）。瞭解[準備的陳述]（http://en.wikipedia.org/wiki/Prepared_statement），並使用[PDO]（http://jayblanchard.net/demystifying_php_pdo.html）。 –

「沒有什麼看起來可行」「你可以更具描述性 –

你可以嘗試'mysql_query（$ sql，$ cn）'，但這是最好的猜測。 –

更新後的mysqli至少：還發現錯誤

$rs = mysqli_query($sql) or die(mysqli_error());

應該

$rs = mysqli_query($cn, $sql) or die(mysqli_error());

和其他代碼：

<?php 
$cn=mysqli_connect("localhost","aalkaabi","leatkifs") or die (mysqli_error()); 
mysqli_select_db("aalkaabi",$cn) or die(mysqli_error()); 
$sql = "SELECT * FROM aalkaabi.Supervisor"; 
$rs = mysqli_query($cn, $sql) or die(mysqli_error()); 
$no=1; 
while($row = mysqli_fetch_array($rs)){?> 
    <div class="panel-group" id="accordion"> 
     <div class="panel panel-default"> 
      <div class="panel-heading"> 
      <h4 class="panel-title"> 
      <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion" href="#<? echo $no; ?>"><? echo $row[0]; ?></a> 
      </h4> 
      </div> 
      <div id="<? echo $no; ?>" class="panel-collapse collapse"> 
       <div class="panel-body"> 
        <h3><? echo $row[0]; ?></h3> 
        <p><? echo $row[1]; ?><br></p> 
        <p><i class="fa fa-envelope-o"></i> 
        <abbr title="Email"><b>Email</abbr>:</b> <a href="mailto:<? echo $row[3]; ?>"><?phpecho $row[2]; ?></a> 
        </p> 
        <p><i class="fa fa-phone"></i> 
        <abbr title="Phone"><b>Phone</abbr>:</b> <?echo $row[3]; ?></p> 
        <p><i class="fa fa-clock-o"></i> 
        <abbr title="Courses Taught"><b>Courses Taught</b></abbr>: <? echo $row[4]; ?></p> 
       </div> 
      </div> 
     </div> 
    </div> 
    <? 
    $no = $no++; 
} 
mysqli_free_result($rs); 
?>

你是說所有的人，或只是行[0] –

所有，刪除引號。當你試圖訪問列名像'row [「user」]' –

時我使用了引號，但是它沒有工作 –
