[thread_PHP]

Hi all
I have written following code works when i import first time, i wrote a condition to check the values are exists in the page before insert so it is stopped working, otherwise inserting the duplicate rows

please correct my code

if(isset($_GET['module']) && !empty($_GET['module'])) 
{

	$module = $_GET['module'];
	$currenttime=time(); 
$filename="CSVFiles/Tempfile".$currenttime."xls"; 
$tmpfile = $_FILES['MemberCSV']['tmp_name'];
	 $upok = move_uploaded_file($tmpfile,$filename);


				$target_path = ''; 
				$csvfilename=$_FILES['MemberCSV']['name']; 
				$fp = fopen($_FILES['MemberCSV']['tmp_name'], 'r') or die('Could not open file!');

			$target_path = "temp/". basename( $_FILES['MemberCSV']['name']); 
				$ext = substr(strrchr($target_path, '.\.'), 1);
			$row = 1; 
	$handle = fopen ($csvfilename,"r");
    $username=""; 

			if($ext == "xls")
			{

			//while ($data = fgetcsv($fp, 1024))
			{
				//$x=0;
				$file_content = file($_FILES['MemberCSV']['tmp_name']); 

				for($i=1; $i<count($file_content); $i++)
				{ 
				$varia= explode("\t", $file_content[$i]);

				if(sizeof($varia) > 1)
				{
