MYSQLI搜索查询崩溃GoDaddy网站服务器

Question

我的搜索查询出现问题，输入搜索多次后该网站崩溃，我不确定是否由于缺乏我在GoDaddy支付的RAM或如果我的搜索查询引发错误或需要太多资源。

请您可以测试这里的搜索：http://cameras.specced.co.uk

请输入几个不同的相机型号，并做几次，搜索查询便会停止工作，该网站将不再工作。

下面是搜索查询：

$model_search_query = $cameras_pdo->prepare("SELECT * FROM models WHERE concat_ws(' ',brand_name,model) LIKE :search LIMIT 5"); 
$model_search_query->execute(array(':search' => "%" . $_POST['search'] . "%")); 

while ($model_search = $model_search_query->fetch(PDO::FETCH_ASSOC)) { 
    $brand_search_query = "SELECT brand FROM brands WHERE id =" . $model_search['brand']; 
    $brand_search = mysqli_fetch_assoc(mysqli_query($cameras, $brand_search_query)); ?> 

     <a href="compare.php?compare_1=<?php echo $model_search['id'];?>"> 



     <div class="search_result"> 
      <div class="search_result_image"> 
       <!-- IMAGE REMOVED TO TEST IF THIS WAS CAUSING THE ISSUE --> 
      </div> 

      <div class="search_result_text"> 
       <?php echo $brand_search['brand'] . " " . $model_search['model']; ?> 
      </div> 
     </div> 
    </a> 
<?php } ?> 

我已经从搜索结果只是柜面它是太大，太多的被装载在下拉式搜寻的同时去除图像造成的问题，但是网站在搜索几次后仍然崩溃。

这是我收到Safari中的错误，

Safari不能打开....因为服务器意外下降的任何帮助

编辑连接...

这里是我的fetch.php的所有内容，包含在AJAX中，当用户搜索标题右上角的搜索栏时，http://cameras.specced.co.uk

<?php ini_set('display_errors', 'On'); ?> 

<!-- REQUIRE DB --> 
<?php 
    $servername = "xxx"; 
    $username = "xxx"; 
    $password = "xxx"; 
    $dbname = "xxx"; 
?> 
<?php 
    $cameras = mysqli_connect($servername, $username, $password, $dbname); 

    $cameras_pdo = new PDO('mysql:host=xxx;dbname=xxx', 'xxx', 'xxx'); 
?> 


<?php 


    $model_search_query = $cameras_pdo->prepare("SELECT * FROM models WHERE concat_ws(' ',brand_name,model) LIKE :search LIMIT 5"); 
    $model_search_query->execute(array(':search' => "%" . $_POST['search'] . "%")); 

    while ($model_search = $model_search_query->fetch(PDO::FETCH_ASSOC)) { 
     $brand_search_query = "SELECT brand FROM brands WHERE id =" . $model_search['brand']; 
     $brand_search = mysqli_fetch_assoc(mysqli_query($cameras, $brand_search_query)); 
p?1=' . $_POST['current'] . "&2=" . $model_search['id'] . '">'; 

      echo '<a href="compare.php?compare_1=' . $model_search['id'] . '">'. 

      '<div class="search_result">' . 
       '<div class="search_result_image">' . 
        '<img src="http://www.specced.co.uk/images/cameras/[' . $model_search['id'] . ']_front.png">' . 
       '</div>' . 

       '<div class="search_result_text">' . 
        $brand_search['brand'] . " " . $model_search['model'] . 
       '</div>' . 
      '</div>' . 
     '</a>'; 
    } 

?>

当网站停止响应，如果您检查开发者控制台在浏览器网络面板，并检查从fetch.php的反应，你会看到最后一个HTTP 200响应仅包含以下内容：

<!-- REQUIRE DB --> 

后续请求为空。因此，我猜PHP在尝试进行数据库连接时会死亡。检查你的error_log并在这里发表你的错误作为评论！完成后您是否关闭数据库连接？
