使用功能mysql_fetch_object或mysql_fetch_row到查詢結果轉換爲數據
$result = mysql_query("SELECT COUNT(`category_id`) as count FROM `products_has_product_category`
WHERE `category_id`=1");
$row = mysql_fetch_object($result);
$count = $row->count;
echo $count;

@Farnabz林不使用PDO，但你在正確的方向明確指出我的。我用$ number = mysql_fetch_row（$ result），然後echo $ number [0] ;.再次感謝你！！！ – Adam
