<?

$objConnect = mysql_connect("localhost","root","root") or die("Error Connect to Database"); // Conect to MySQL
$objDB = mysql_select_db("mydatabase");

$objCSV = fopen("customer.csv", "r");
while (($objArr = fgetcsv($objCSV, 1000, ",")) !== FALSE) {

	$strSQL = "SELECT * FROM customer WHERE CustomerID = '".$objArr[0]."' ";
	$objQuery = mysql_query($strSQL);
	$objResult = mysql_fetch_array($objQuery);
	if($objResult)
	{
			// Update
			$strSQL = "UPDATE customer  SET Name = '".$objArr[1]."' ";
			$strSQL .=",Email = '".$objArr[2]."' ";
			$strSQL .=",CountryCode = '".$objArr[3]."' ";
			$strSQL .=",Budget = '".$objArr[4]."' ";
			$strSQL .=",Used = '".$objArr[5]."' ";
			$strSQL .="WHERE CustomerID = '".$objArr[0]."' ";
			$objQuery = mysql_query($strSQL);
	}
	else
	{
			// Insert
			$strSQL = "INSERT INTO customer ";
			$strSQL .="(CustomerID,Name,Email,CountryCode,Budget,Used) ";
			$strSQL .="VALUES ";
			$strSQL .="('".$objArr[0]."','".$objArr[1]."','".$objArr[2]."' ";
			$strSQL .=",'".$objArr[3]."','".$objArr[4]."','".$objArr[5]."') ";
			$objQuery = mysql_query($strSQL);
