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.'"].'"
$i包含我试图附加到$_SESSION变量的数字。有什么建议么？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'] .= '
