PHP注意：未定义的偏移量

我想上传的CSV数据到MySQL不包括头。 我的脚本有效，但是显示错误

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

执行查询后的消息。 什么是错的，我该如何解决这个问题。

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

“未定义的偏移”意味着代码被引用到缺less数组索引。 为了防止这个，你应该像这样使用：

 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";
