รบกวนถามเรื่อง PHPCSV หน่อยค่ะ ต้องการให้วนค่า ตามที่เรากำหนดไว้ค่ะ

<?php
move_uploaded_file($_FILES["fileCSV"]["tmp_name"],$_FILES["fileCSV"]["name"]); // Copy/Upload CSV

$objConnect = mysql_connect("localhost","root","1234") or die("Error Connect to Database"); // Conect to MySQL
$objDB = mysql_select_db("inoue");

$objCSV = fopen($_FILES["fileCSV"]["name"], "r");
$tmp = "000000";
while (($objArr = fgetcsv($objCSV, 1000, ",")) !== FALSE) {
		$marker = $objArr[0];


		if ($marker == "500140"){ 
			if($tmp != "")
			{
					$tmp = "500140";
			}
		}else if ($marker == "500125") {
			if($tmp != "")
			{
					$tmp = "500125";
			}
		}

		echo $tmp."__".$marker."<br>";
}
fclose($objCSV);
unlink($_FILES["fileCSV"]["name"]);
echo "Import Done.";		
?>

		if (trim($marker) == "500140"){ 
			$tmp = "500140";
		}
		if (trim($marker) == "500125") {
			$tmp = "500125";
		}
