php – 登录后台更改

我有一个登录系统,一旦您登录,就会将登录框更改为帐户信息.我希望在帐户信息周围有一个背景和边框,而不是登录框.我试图添加一个< div class>围绕if($session-> logged_in),但似乎没有用.

这是我登录的代码.我只需要帮助添加一个div类.

<?PHP
/**
 * User has already logged in,so display relavent links,including
 * a link to the admin center if the user is an administrator.
 */
if ($session->logged_in) { 
    echo "<div class='welcome'><b>" . $session->username . "</b></div>" . "<div class='account'><a href=\"userinfo.PHP?user=$session->username\">My Account</a></div> &nbsp;&nbsp;" . "<div class='account'><a href=\"useredit.PHP\">Edit Account</a></div> &nbsp;&nbsp;";
    if ($session->isAdmin()) {
        echo "<div class='account'><a href=\"admin/admin.PHP\">Admin Center</a></div> &nbsp;&nbsp;";
    }
    echo "<div class='account'><a href=\"process.PHP\">logout</a>]</div>";
} else {
?>

if ($session->isAdmin()) {
    echo "<div class='accountArea'>";   
    echo "<div class='account'><a href=\"admin/admin.PHP\">Admin Center</a></div> &nbsp;&nbsp;";
    echo "</div>";
}
