条件不适合我

Question

我需要从MySQL数据库中导出CSV工作正常，但是如果有一些条件，其中第二个不适合我。它总是出口缺席，假日和周日。但不打印$att[$date]变量$month包含年份和月份。喜欢 - 2016-02

$res1 = mysql_query("SELECT *, CONCAT(MIN(`IN_AM`),'  ', MAX(`OUT_PM`)) as io_time FROM bio_attandence where date(STR_TO_DATE(attandence_date,'%d/%m/%Y')) >= date('$startdate') AND date(STR_TO_DATE(attandence_date,'%d/%m/%Y')) < date('$enddATE') AND bio_id=".$row['form_no']." GROUP BY bio_id, attandence_date order by attandence_date ");
$att = array();
while ($row1 = mysql_fetch_array($res1)) {
   $strtodate = $row1['attandence_date'];
   $dateq = str_replace('/', '-', $strtodate);
   $dateDate = date('Y-m-d', $dateq);
  $att[$dateDate] = $row1['io_time'];   
}

for($i=1; $i<32;$i++){
    $i = str_pad($i, 2, '0', STR_PAD_LEFT);
    $date = $month.'-'.$i;
    $val = '';
        if(strtotime($date) > strtotime(date('Y-m-d'))){
            $val = " ";
        }elseif(isset($att[$date])){
            $val = $att[$date];
        }elseif(isset($holidays[$date])){
            $val = $holidays[$date];
        }else{
            $val = (date('D', strtotime($date)) == 'Sun')? 'Sunday': 'Absent';
        }
    ?>
    <Cell>
      <Data ss:Type="String"> <?php echo( $val ); ?></Data>
    </Cell>
<?php }?>
