You can try this.
你可以试试这个。
function lists_session($key, $value = NULL) {
static $storage;
if ($value) {
$storage[$key] = $value ;
$_SESSION['lists'][$key] = $value ; // I use 'lists' in case some other module uses 'type' in $_SESSION
}
else if (empty($storage[$key]) && isset($_SESSION['lists'][$key])) {
$storage[$key] = $_SESSION['lists'][$key];
}
return $storage[$key];
}
So, to save a variable in Session:
因此，要在 Session 中保存变量：
lists_session("s_key", "value");
And to retrieve the value, just use:
要检索值，只需使用：
$myVar = lists_session("s_key");

I have no problem of using the $_SESSION variable in my own module. Just keep in mind to create a unique sub key for your data.
我在自己的模块中使用 $_SESSION 变量没有问题。请记住为您的数据创建一个唯一的子键。
$_SESSION['mydata'] = array(of your data);

Remember to serialise your data such as array, obj... before save to session. $arr = array(); $_SESSION['mysession'] = serialise($arr);
请记住在保存到会话之前序列化您的数据，例如数组，obj...。$arr = 数组(); $_SESSION['mysession'] = serialise($arr);
