我需要帮助打印一个php multidementional阵列

Question

我想打印一个数组。

第一个例子。

$result2 = mysql_query("SELECT 
ps_product_attribute.id_product_attribute AS attribute_id, 
ps_advanced_attributes.pack_product_id AS base_product, 
ps_advanced_attributes.pack_product_qty AS qty_base_product, 
ps_stock_available.quantity AS base_product_on_hand, 
FLOOR(ps_stock_available.quantity/ps_advanced_attributes.pack_product_qty) AS available_to_customer 
FROM ps_product_attribute 
JOIN ps_advanced_attributes ON ps_advanced_attributes.attribute_id = ps_product_attribute.id_product_attribute 
JOIN ps_stock_available ON ps_stock_available.id_product = ps_advanced_attributes.pack_product_id 
ORDER BY ps_product_attribute.id_product_attribute ASC, ps_stock_available.quantity DESC"); 

echo '<pre>'; 
WHILE($db_field2 = mysql_fetch_array($result2)){ 
print_r($db_field2);} 
echo '</pre>'; 

给出了这样的结果......只有

Array(
    [0] => 6703 
    [attribute_id] => 6703 
    [1] => 382 
    [base_product] => 382 
    [2] => 1 
    [qty_base_product] => 1 
    [3] => 69 
    [base_product_on_hand] => 69 
    [4] => 69 
    [available_to_customer] => 69 
) 

这一结果

例如2 ...

$result2 = mysql_query("SELECT 
ps_product_attribute.id_product_attribute AS attribute_id, 
ps_advanced_attributes.pack_product_id AS base_product, 
ps_advanced_attributes.pack_product_qty AS qty_base_product, 
ps_stock_available.quantity AS base_product_on_hand, 
FLOOR(ps_stock_available.quantity/ps_advanced_attributes.pack_product_qty) AS available_to_customer 
FROM ps_product_attribute 
JOIN ps_advanced_attributes ON ps_advanced_attributes.attribute_id = ps_product_attribute.id_product_attribute 
JOIN ps_stock_available ON ps_stock_available.id_product = ps_advanced_attributes.pack_product_id 
ORDER BY ps_product_attribute.id_product_attribute ASC, ps_stock_available.quantity DESC"); 

echo '<pre>'; 
WHILE($db_field2 = mysql_fetch_array($result2)){ 
print_r($db_field2);} 
echo '</pre>'; 

篮网这样的结果......

正如你所看到的，很多结果，但不是我期待看到的。在这两个例子中，我都得到重复的数据。

我在这里做错了什么？我认为第一个例子应该已经打印了数组的全部内容。

Answer 1

你应该先提取所有结果到数组，然后才打印出来

$result = []; 
while ($row = mysql_fetch_assoc($result2)){ 
    $result[] = $row; 
} 
print_r($result); 

UPD：除掉重复数据的使用mysql_fetch_assoc，而不是mysql_fetch_array

UPD2：考虑使用mysqli扩展，而不是的MySQL。 PHP.net
