我需要幫助打印一個php multidementional陣列

Question

我想打印一個數組。

第一個例子。

$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>'; 

給出了這樣的結果......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 
) 

這一結果

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>'; 

籃網這樣的結果......

正如你所看到的，很多結果，但不是我期待看到的。在這兩個例子中，我都得到重複的數據。

我在這裏做錯了什麼？我認爲第一個例子應該已經打印了數組的全部內容。

Answer 1

你應該先提取所有結果到數組，然後纔打印出來

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

UPD：除掉重複數據的使用mysql_fetch_assoc，而不是mysql_fetch_array

UPD2：考慮使用mysqli擴展，而不是的MySQL。 PHP.net
