The function is not working. I would like ot add each line to the mysql database to the description field, and a number to the value field

 $fp = fopen($filename,"r");
    $number=0;

    //parse the csv file row by row
while(($row = fgetcsv($fp,"500",",")) != FALSE)
{
    $number++;
    //insert csv data into mysql table
    $sql = "INSERT INTO 'description' (descID`, `desc`) VALUES($number ,$row)";
    if(!mysqli_query($connection, $sql))
    {
        die('Error : ' . mysqli_error());
    }
}
