php下面程式碼分級完整實現打造提供無限註解的類別

下面提供一个PHP的无限分级类代码，想要实现无限分级类的朋友们可以试试。Bug已经检查修正过，直接复制代码就能使用尖括号需要替换一下）。

1、数据库ProductShow中有b_mtype表，建表语句如下：

<ol class="dp-sql">
<li class="alt"><span><span class="keyword">CREATE</span><span> </span><span class="keyword">TABLE</span><span> `b_mtype` (  </span></span></li>

</li>
<li class="alt">

</li>
<li class="">
<span>  </span><span class="keyword">PRIMARY</span><span> </span><span class="keyword">KEY</span><span>  (`typeid`)  </span>
</li>
<li class="alt"><span>) TYPE=MyISAM;  </span></li>
<li class=""><span> </span></li>
</ol>

絕對會話超時有什麼區別？絕對會話超時有什麼區別？May 03, 2025 am 12:21 AM

絕對會話超時從會話創建時開始計時，閒置會話超時則從用戶無操作時開始計時。絕對會話超時適用於需要嚴格控制會話生命週期的場景，如金融應用；閒置會話超時適合希望用戶長時間保持會話活躍的應用，如社交媒體。

如果會話在服務器上不起作用，您將採取什麼步驟？如果會話在服務器上不起作用，您將採取什麼步驟？May 03, 2025 am 12:19 AM

服務器會話失效可以通過以下步驟解決：1.檢查服務器配置，確保會話設置正確。 2.驗證客戶端cookies，確認瀏覽器支持並正確發送。 3.檢查會話存儲服務，如Redis，確保其正常運行。 4.審查應用代碼，確保會話邏輯正確。通過這些步驟，可以有效診斷和修復會話問題，提升用戶體驗。

設置httponly標誌對會話cookie至關重要，因為它能有效防止XSS攻擊，保護用戶會話信息。具體來說，1）httponly標誌阻止JavaScript訪問cookie，2）在PHP和Flask中可以通過setcookie和make_response設置該標誌，3）儘管不能防範所有攻擊，但應作為整體安全策略的一部分。
