MYSQLI搜索查詢崩潰GoDaddy網站服務器

Question

我的搜索查詢出現問題，輸入搜索多次後該網站崩潰，我不確定是否由於缺乏我在GoDaddy支付的RAM或如果我的搜索查詢引發錯誤或需要太多資源。

請您可以測試這裏的搜索：http://cameras.specced.co.uk

請輸入幾個不同的相機型號，並做幾次，搜索查詢便會停止工作，該網站將不再工作。

下面是搜索查詢：

$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 } ?> 

我已經從搜索結果只是櫃面它是太大，太多的被裝載在下拉式搜尋的同時去除圖像造成的問題，但是網站在搜索幾次後仍然崩潰。

這是我收到Safari中的錯誤，

Safari不能打開....因爲服務器意外下降的任何幫助

編輯連接...

這裏是我的fetch.php的所有內容，包含在AJAX中，當用戶搜索標題右上角的搜索欄時，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>'; 
    } 

?>

當網站停止響應，如果您檢查開發者控制檯在瀏覽器網絡面板，並檢查從fetch.php的反應，你會看到最後一個HTTP 200響應僅包含以下內容：

<!-- REQUIRE DB --> 

後續請求爲空。因此，我猜PHP在嘗試進行數據庫連接時會死亡。檢查你的error_log並在這裏發表你的錯誤作爲評論！完成後您是否關閉數據庫連接？
