ขอคำปรึกษาเกี่ยวกับการ import File CSV to MySQL ที่และแถวครับ

<?php  
$connect = mysql_connect("localhost","root","computer"); 
mysql_select_db("csv",$connect); 
mysql_query("SET NAMES utf8");
if ($_FILES[csv][size] > 0) { 
    $file = $_FILES[csv][tmp_name]; 
    $handle = fopen($file,"r"); //
    do { 
        if ($data[0]) { 
            mysql_query("INSERT INTO contacts (id_student) VALUES 
                ( 
                      '".addslashes($data[0])."' 
                ) 
            "); 
        } 
    } while ($data = fgetcsv($handle,1000,",","'")); 
    // 

    //redirect 
    header('Location: import.php?success=1'); die; 

} 

?>
