PHP通知: Undefined offset

Question

我想将csv数据上传到mysql，不包括标题。我的脚本可以工作，但显示错误

Notice: Undefined offset: 32 in C:\wamp\www\mvc\excel\upload.php on line 38

执行查询后的消息。出了什么问题以及如何修复它。

这是我的代码

if (isset($_POST['submit'])) {


    //Import uploaded file to Database

    $file = $_FILES['filename']['tmp_name']; 

    $handle = fopen($file,"r"); 

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

            $import="INSERT into contacts 
                  (name, contacttype, nationality, mobile1, country1,
                  email1, phone, fax, twon, area, restatus, retype, 
                  reproject1, contactgroup, freezone1, gender, 
                  dateofbirth, married, children, educationlevel, 
                  jobsector, driverslicense, media, media2, age, 
                  salary, created, upload, image, companyname, 
                  businesscategory, subcategory, jobrole, upload_id)
                  values('$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";

        //view upload form
    }
}

谢谢

“ undefined offset ”意味着代码引用了缺失的数组索引。 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";
