How Do I rename CSV file when uploading and insert into database with renam and after insert show csv column headings in buttons

Answer 1

CSV headers (if present) are located right on the first line. So you can simply do:

$delimiter = ',';
$headers = fgetcsv(fopen($file_path, 'r'), $delimiter);

if (is_array($headers)) {
    foreach($headers as $header) {
         echo "<input type=\"button\" name=\"$header\"
               value=\"$header\"/>'";
        }
    }
}

And to rename the file while moving, you should change the second parameter of move_uploaded_file() to the desired name. If you like, you can get a unique ID using sha1_file($_FILES['file1']['tmp_name']). It will also avoid duplicated storage of identical files.
