PHP导入到数据库字段中信息不完整

    $q="insert into hotel_activities_2 (hotel_id,start_date,end_date,content,s_type) values ";
while($data=fgetcsv($handle,10000,","))
{

    if($data[0] =='')
    {
     continue;
    }
    $q .= "('".$data[0]."','".$data[1]."','".$data[2]."','".$data[3]."','".$data[4]."'),";}
$q = substr($q,0,-1);
    $db->query($q);导入进的数据不是为空，就是数据信息不完整，怎么回事
