[php]
<?php ob_start();session_start();require_once("session_class.php");if (isset($_SESSION["session_accounts"])) { echo "初始化session值<br>";
$_SESSION["session_accounts"] = new accounts;
$_SESSION["session_accounts"]->set_username("liujifeng");

$_SESSION["session_email"]->set_email("[email protected]");

}

echo "取得session值<br>";

[php]
<?php ob_start();session_start();require_once("session_class.php");
if (isset($_SESSION["session_accounts"])) { echo "空值";
}
else
{

echo "取得session值<br>"; $accounts = $_SESSION["session_accounts"];

echo $accounts->text();
}
?>
[/php]执行到session_getvalue.php出现以下错误:
