foreach内でmysqlを選択

Question

foreachでMySQLを選択するにはどうすればよいですか？

私のコードは次のとおりです。

$start = new DateTime($giris); 
$end = new DateTime($cikis); 
$interval = DateInterval::createFromDateString('1 day'); 
$period = new DatePeriod($start, $interval, $end); 
foreach ($period as $dt) { 
    $datex = $dt->format("Y-m-d"). PHP_EOL; 
    $sorgu = mysql_query("SELECT * FROM takvimler WHERE `date`='$datex'"); 
    $veri = mysql_fetch_assoc($sorgu); 
    $don = $veri['price']; 
    echo $don; 
} 

注：削除 `：私はecho $don;

$start = new DateTime($giris); 
$end = new DateTime($cikis); 
$interval = DateInterval::createFromDateString('1 day'); 
$period = new DatePeriod($start, $interval, $end); 
foreach ($period as $dt) { 
$datex = $dt->format("Y-m-d"). PHP_EOL; 
$sorgu = mysql_query("SELECT * FROM takvimler WHERE `date`='$datex'"); 
$veri = mysql_fetch_assoc($sorgu); 
$don .= $veri['price']; 

} 
echo $don;
