使用PHP将CSV文件导入MySQL

I'm struggling with a problem.

So what i try is to import a csv file into a table.

Code:

-

But here's the catch: When import a file. It says; Success!, but nothing had imported.

What am I not seeing?

Thanks!

EDIT:

-

From the edited code I only getting the message: $satus=toegevoegd. Translated: Added to database. But there is no data in the table... I really dont know what im doing wrong.

EDIT 2;

There's lots of good advice in the help centre - notably How to create a Minimal, Complete, and Verifiable example.

As it stands there is no error checking in your code (which should be required for production use, never mind development). That the script ends with a redirect makes it rather hard to report detailed events for debugging (but these can be written to log files).

ini_set('error_reporting', E_ALL);

I am guessing this is the mysqli extension you are using here - if a query or connection fails, it does not trigger an eror in PHP, you need to poll mysqli_error() and/or check the return value from the operation.

The SELECT/UPDATE/INSERT is very inefficient - a better approach would be to

• use REPLACE if you always want to override the existing data,
• OR, if you want to be a bit more selective
  • attempt the insert then handle duplicate key conflicts when they arise
  • or use a trigger to multiplex the insert/update behaviour.

Depending on how the CSV is constructed you will get an error for the last line in the file - you might want to check 4<=count($line) before attempting to access the record.

Your code is vulnerable to SQL Injection.
