如何使用id从阵列中取消链接图片

Trying to unlink pictures using an id array it deletes the accounts but not the pictures can anyone help please, the selectrow id is different from id thanks

$delid = $_POST['selectrow'];
$nc = count($delid);

for($i=0;$i<$nc;$i++)
{
    $did = $delid[$i];
    $a = array($eg_Result1['id']);

    foreach ($a as $v) {
        // Get the file name
        // Get the folder path
        unlink('../images/userpics/'.$v.'.png');
    }

    setcookie('selectdelete', success);

    mysqli_query( $eg_objConn1, "DELETE FROM `users` WHERE `xkey` = '".$did."'");
}

// Go to page
header("Location: manage_adminpanel.php?s=".@$_COOKIE['sort']."&xpage=".@$_COOKIE['xpage']."");
exit;
