Question

ich有一个大问题。我在Apache（Arch Linux）上开发了一个本地PHP项目，在线PHP将Session键设置为null。我使用Class :: serialize和Class :: unserialize在会话中保存对象。这就是我的PHP代码，用于此功能：

public function serialize() {
    $data = new \stdClass();
    $data->content = $this->content;
    $data->key = $this->key;
    $data->file = $this->file;

    return serialize($data);
}
public function unserialize($data) {
    $data = unserialize($data);

    $this->content = $data->content;
    $this->key = $data->key;
    $this->file = $data->file;
    $this->crypt = new \Kryptomat\Crypt\Mcrypt($this->key);
}

我的PHP.ini：

session

Registered save handlers    files user
Registered serializer handlers  php_serialize php php_binary

Directive   Local Value Master Value
session.auto_start  Off Off
session.cache_expire    180 180
session.cache_limiter   nocache nocache

session.use_cookies On  On
session.use_only_cookies    On  On
session.use_strict_mode Off Off
session.use_trans_sid   0   0

这是服务器PHP.ini：

Answer 1

正在开始会话？开始会话呼叫session_start();

在序列化后，您没有在会话中保存数据使用$_SESSION['data'] = $data;

保存会话中的数据

然后，您可以通过$_SESSION['data']检索此数据。之后使用unserialize函数取消序列化对象。

希望它会对你有所帮助。

PHP Session下一页调用null
