php求取时间范围并传入数据库，页面上显示几天几月几年

$startTime = $_GPC['h_time']['start'];
$endTime = $_GPC['h_time']['end'];
echo $startTime.'<hr>';

echo $endTime.'<hr>';
// $h_time= implode(",",$_GPC['h_time']);
$h_time = (strtotime($endTime)-strtotime($startTime))/3600;
echo $h_time;

$data = array("uniacid"=>$uniacid,"h_name"=>$_GPC['h_name'],"h_time"=>$h_time,"h_age"=>$_GPC['h_age'],"h_sex"=>$_GPC['h_sex'],"h_jname"=>$_GPC['h_jname'],"h_jthumb"=>$_GPC['h_jthumb'],"h_zfangan"=>$_GPC['h_zfangan'],"h_zname"=>$_GPC['h_zname']);
echo "<pre>";print_r($data);echo "</pre>";
