Need to delete file (unlink) from directory listing [Archive]

Someone asked me how to delete a file using PHP. They have done a directory listing to list all the files in a directory. Users can download the files they want by clicking on the file. How could I put a "Delete" link beside each file name and be sure that it will specifically delete THAT file?

Thanks

<?
if(isset($_POST['upload']))
{
$uploadDir="filefolderpath/";
$fileName = $_FILES['file']['name'];

$tmpName = $_FILES['file']['tmp_name'];
$fileSize = $_FILES['file']['size'];
$fileType = $_FILES['files']['type'];

$filePath = $uploadDir . $fileName;

$result = move_uploaded_file($tmpName, $filePath);
if (!$result) {
echo "Error uploading file";
exit;

}
}
if($_GET)
{
$var=$_GET["var"];
$path="filefolderpath/".$var;

$status=unlink($path);

}?>
