    //loop through the csv file and insert into database 
    for ($lines = 0; $data = fgetcsv($handle,1000,",",'"'); $lines++) {
        if ($lines == 0) continue;
        if ($data[0]) {

“Undefined offset”表示代码被称为缺少数组索引。为了防止这种情况，你应该这样使用：

for ($lines = 0; $data = fgetcsv($handle,1000,",",'"'); $lines++) {
        if ($lines == 0) continue;
        for ($i = 0; $i <= 32; $i ++)
        {
            if (!isset($data[$i]))
                $data[$i] = ''; 
        }

                $import="INSERT into contacts 
                  (name, contacttype, nationality, mobile1, country1,
                  email1, phone, fax, twon, area, restatus, retype, 
                  reproject1, contactgroup, freezone1, gender, 
                  dateofbirth, married, children, educationlevel, 
                  jobsector, driverslicense, media, media2, age, 
                  salary, created, upload, image, companyname, 
                  businesscategory, subcategory, jobrole, upload_id)
                  values('$data[0]', '$data[1]','$data[2]','$data[3]',
                         '$data[4]', $data[5]','$data[6]','$data[7]',
                         '$data[8]','$data[9]','$data[10]','$data[11]',
                         '$data[12]','$data[13]','$data[14]','$data[15]',
                         '$data[16]','$data[17]','$data[18]','$data[19]',
                         '$data[20]','$data[21]','$data[22]','$data[23]',
                         '$data[24]','$data[25]','$data[26]','$data[27]',
                         '$data[28]','$data[29]','$data[30]','$data[31]',
                         '$data[32]','$uploadid') ";
                print $import;
                mysql_query($import) or die(mysql_error());
}
fclose($handle);
print "Import done";

PHP注意：未定义的偏移量
