一個SQL查詢中將使用兩個foreach循環

Question

我有兩個數組：

$armortype = array(5,8);

和

$slotarray = array(1,2,3,5,6,7,8,9,10,11,11,12,16);

如何將這兩個組合成一個foreach循環？ 這是當前的代碼：

foreach($slotarray as $slot)
{
    foreach($armortype as $armor)
        $itempack = mysql_query("SELECT * FROM db WHERE ItemLevel BETWEEN $formlevel1 AND $formlevel2 AND InventoryType =$slot AND Quality<5 AND AllowableClass in ('$formclass', '-1','2047','32767') AND Material=$armor ORDER BY RAND() LIMIT 1");
    }
}

我的$ armor值不正確。

Answer 1

$itempack = mysql_query("SELECT * 
    FROM db
    WHERE ItemLevel BETWEEN $formlevel1 AND $formlevel2
        AND InventoryType = in ('". implode("', '", $slotarray) ."')
        AND Quality<5
        AND AllowableClass in ('$formclass', '-1','2047','32767')
        AND Material = in ('". implode("', '", $armortype) ."')
    ORDER BY RAND()
    LIMIT 1");

那應該做。 放置它而不是兩個循環。 它只運行一個查詢，而不是數十個查詢...
