将变量追加到 $_SESSION 变量的末尾

Question

我正在尝试将一个数字附加到 PHP $_SESSION变量的末尾，但由于某种原因，该数字没有附加。这是我遇到问题的代码部分：

value="'.$_SESSION["fname_'.$i.'"].'"

$i包含我尝试附加到$_SESSION变量的数字。有什么建议吗？谢谢

//Loop through the number of stored in $_SESSION['management-count'] and print out that many sections
    $_SESSION['management-member-template'] = '' ;
    for ($i = 1; $i <= $_SESSION['management-count']; $i++) {
        $_SESSION['management-member-template'] .= '

通了。这是解决方案：

错误：value="'.$_SESSION["fname_'.$i.'"].'"
