PHP Session next page call null

Question

這有個大問題。我在Apache（Arch Linux）上開發了一個本地PHP項目，在線PHP將會話密鑰設置爲null。我使用Class :: serialize和Class :: unserialize保存會話中的對象。而這就是我的PHP代碼此功能：

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

session.cache_expire 180 180

這是服務器的php.ini：

Answer 1

開始會議？ 啓動會議呼叫session_start();

你是不是在保存會話中的數據，採用序列$_SESSION['data'] = $data;

然後下一個頁面保存在會話中的數據可以通過$_SESSION['data']檢索這些數據之後。之後，使用您的反序列化函數對序列化對象進行序列化。

希望它能幫助你。
