อยาก SORT Array ให้ตรงตาม Array หลักครับ ถ้าอันไหนไม่มีให้เป็น "-" ด้วยครับ

$arrCurrency = array(
    'USD 50-100','USD 5-20','USD 1-2','GBP','EUR','JPY','HKD','MYR','SGD', 'BND','CNY','IDR','INR','KRW',
    'LAK','PHP','TWD','AUD','NZD','CHF','DKK','NOK','SEK','CAD','RUB','VND','ZAR','AED','BHD','OMR','QAR','SAR'
);

$arrSCB = 
Array
(
    [0] => Array
        (
            [currency] => USD 50-100
            [buy] => 35.03
            [sell] => 35.73
        )

    [1] => Array
        (
            [currency] => USD 5-20
            [buy] => 34.55
            [sell] => 35.66
        )

    [2] => Array
        (
            [currency] => USD 1-2
            [buy] => 34.19
            [sell] => 35.64
        )

    [3] => Array
        (
            [currency] => EUR
            [buy] => 39.56125
            [sell] => 40.95625
        )

    [4] => Array
        (
            [currency] => GBP
            [buy] => 53.34625
            [sell] => 55.2575
        )

    [5] => Array
        (
            [currency] => JPY
            [buy] => 28.935
            [sell] => 30.58
        )

    [6] => Array
        (
            [currency] => SGD
            [buy] => 24.745
            [sell] => 25.79375
        )

    [7] => Array
        (
            [currency] => HKD
            [buy] => 4.43095
            [sell] => 4.74
        )
.
.
.

$arrSCB [$i]['currency'] = '-';
$arrSCB [$i]['buy'] = '-';
$arrSCB [$i]['sell'] = '-';
