PHP输出查询

Question

林新的论坛，但希望有人能够给我一个手IM挣扎..

我的代码如下，我出口从Zen Cart的数据库CSV文件

$products_cost = 
    "select p.products_id, pd.products_name, p.products_quantity, ". 
     "p.products_cost, (p.products_quantity*p.products_cost) AS products_total_cost, ". 
     "p.products_type ". 
    "from " . TABLE_PRODUCTS . " p, " . TABLE_PRODUCTS_DESCRIPTION . " pd ". 
    "where p.products_id = pd.products_id and pd.language_id='" . $_SESSION['languages_id'] . "' ". 
    "order by (p.products_cost) DESC, p.products_cost desc, pd.products_name"; 

    $products_stock = $db->Execute($products_cost); 

//Start Of Output for Stock File 

$output = array();  
$output["tx_type"]='ST';   
$output["Stock_Code"]= $products_stock->fields['products_id']; 
$output["Qty"]= $products_stock->fields['products_quantity']; 
$output["Description"]= $products_stock->fields['products_name']; 
$output["CostPriceEx"]= $products_stock->fields['products_cost']; 
$output["TotalCostEx"]= $products_stock->fields['products_cost'] * $products_stock->fields['products_quantity']; 

zen_sages_fwrite($output); 

$stimer = microtime_float(); 

运行代码时，我得到如下的输出，但不显示数据库中的每个产品，它显示的是相同的？

ST,1149,10,350gsm A6 Glossy Postcards,290.0000,2900 
ST,1149,10,350gsm A6 Glossy Postcards,290.0000,2900 
ST,1149,10,350gsm A6 Glossy Postcards,290.0000,2900 
ST,1149,10,350gsm A6 Glossy Postcards,290.0000,2900 
ST,1149,10,350gsm A6 Glossy Postcards,290.0000,2900 
ST,1149,10,350gsm A6 Glossy Postcards,290.0000,2900 
ST,1149,10,350gsm A6 Glossy Postcards,290.0000,2900 
ST,1149,10,350gsm A6 Glossy Postcards,290.0000,2900 
ST,1149,10,350gsm A6 Glossy Postcards,290.0000,2900 
ST,1149,10,350gsm A6 Glossy Postcards,290.0000,2900 
ST,1149,10,350gsm A6 Glossy Postcards,290.0000,2900 

我曾尝试加入$products_stock->MoveNext();

但dosent缝有任何影响，

感谢大家提前

我的代码现在看起来像

//开始输出圣ock文件

$output = array(); while (!$products_stock->EOF) { 


$output["tx_type"]='ST'; 


$output["Stock_Code"]= $products_stock->fields['products_id']; 


$output["Qty"]= $products_stock->fields['products_quantity']; 


$output["Description"]= $products_stock->fields['products_name']; 


$output["CostPriceEx"]= $products_stock->fields['products_cost']; 


$output["TotalCostEx"]= $products_stock->fields['products_cost'] * $products_stock->fields['products_quantity']; 

$ products_stock-> MoveNext;

} 

zen_sages_fwrite（$ output）;

$ stimer = microtime_float（）;

在回答形式把这样你就可以得到它的工作更快^^ 你想要的东西，如：

while(!$products_sock->EOF) { 
    $output = array();  
    $output["tx_type"]='ST';   
    $output["Stock_Code"]= $products_stock->fields['products_id']; 
    $output["Qty"]= $products_stock->fields['products_quantity']; 
    $output["Description"]= $products_stock->fields['products_name']; 
    $output["CostPriceEx"]= $products_stock->fields['products_cost']; 
    $output["TotalCostEx"]= $products_stock->fields['products_cost'] * $products_stock->fields['products_quantity']; 

    zen_sages_fwrite($output); 
    $products_stock->MoveNext(); 
} 

随着您在上面添加，您覆盖$output与每一个循环的代码，这会写它的每一个循环然后覆盖它。

或者试试：

for($i=0;$i<$products_stock->rowCount();$i++) { 
    $output = array();  
    $output["tx_type"]='ST';   
    $output["Stock_Code"]= $products_stock->fields['products_id']; 
    $output["Qty"]= $products_stock->fields['products_quantity']; 
    $output["Description"]= $products_stock->fields['products_name']; 
    $output["CostPriceEx"]= $products_stock->fields['products_cost']; 
    $output["TotalCostEx"]= $products_stock->fields['products_cost'] * $products_stock->fields['products_quantity']; 

    zen_sages_fwrite($output); 
    $products_stock->MoveNext(); 
}
