sql - Undefined variable data when I try to import a csv file in php -


im trying import csv file in sql database using php.

i have code

<?php        echo $_files['userfile']['name'];      echo $_files['userfile']['size'];      include ("accesobd.php");      if ($_files['userfile']['size'] > 0) {         echo "el archivo contiene informacion";          $file = $_files['userfile']['tmp_name'];          $handle = fopen($file,"r");          $data2 = fgetcsv($handle,1000,",","'");          {          if ($data[0]) {              echo "entramos en el import";             mysql_query("insert alumno (nombre, apellidos, correoelectronico) values                  (                      '".addslashes($data[0])."',                      '".addslashes($data[1])."',                      '".addslashes($data[2])."'                  )              ");          }          } while ($data = fgetcsv($handle,1000,",","'"));        }   ?>

i file information correctly, , accesobd it´s class manage conexion database, error data variable not declared.

the point loop enters correct number of times should , prints correct number of times echo "entramos en el import", inserts nothing find no such variable data.

the literal error gives me browser is

alumnos.csv80el archivo contiene informacion notice: undefined variable: data in c:\xampp\htdocs\iprofesor\importaralumnoss.php on line 17 entramos en el importentramos en el import

pd sorry if have bad english, it´s first time trying make formal question using language :)

you defined $data2 , use $data undefined.

$data2 = fgetcsv($handle,1000,",","'");      {      if ($data[0]) {
