从类[复制]上的函数打印值

i have this function on class called Bills that return three value when calling it.

function GetCashierDetail ($UserID){
        $GetCashierID = "SELECT cashiers_CashierID,cashiers_Total,cashiers_Last_Total 
        FROM `cashiers` 
        WHERE `cashiers_CashierCloseDate` is null and `cashiers_Status`='0' 
        and `cashiers_Delete` = '0' and `cashiers_User` = '".$UserID."'";
        $objQueryCashierID = mysql_query($GetCashierID) or die ("Error Query [".$strSQL."]");
        $GetCashierIDResult = mysql_fetch_array($objQueryCashierID);
        $BillsCashierID = $GetCashierIDResult['cashiers_CashierID'];
        $CashierTotal=$GetCashierIDResult['cashiers_Total']; 
        $CashierLastTotal=$GetCashierIDResult['cashiers_Last_Total']; 
        $num=mysql_affected_rows();
        // Return Data
        return $cashier_data = array('cashierId'=>$BillsCashierID ,
                          'CashierTotal'=>$CashierTotal ,
                          'CashierLastTotal'=>$CashierLastTotal );                      

}

now when call this function

$BillDraftSubmit = new Bills;
$BillDraftSubmit->GetCashierDetail(71);

i need to print the $cashier_data on variable like this

$ID = $BillsCashierID to using it on other way.

how can i read the value from this function from class

</div>

If it is a method you can use this:

$BillDraftSubmit = new Bills();
$data=$BillDraftSubmit->GetCashierDetail(71);
$id=$data["cashierId"];

Be careful, because in you question you have

$BillDraftSubmit = new Bills;

instead of

$BillDraftSubmit = new Bills();

If it is not a method you can use this:

$data=GetCashierDetail(71);
$id=$data["cashierId"];

your $ID should have the array in it

use

foreach($ID as $key => $val) {
 echo $val['cashierId'];
 ....
 }
