</p> <p>我們的專案涉及建立表單，使用者可以在其中輸入訊息，將提交的資料儲存在 cookie 中，然後查看或刪除 cookie 資料。在本教學結束時，您將了解如何在 PHP 中設定、檢索和刪除 cookie。 </p> <hr> <h2> 什麼是 Cookie？ </h2> <p>Cookie 是儲存在使用者瀏覽器上的小檔案。它們允許網(wǎng)路伺服器儲存特定於使用者的資料並在後續(xù)存取時檢索它。在 PHP 中，您可以使用 setcookie() 函數(shù)來建立或更新 cookie，並使用 $_COOKIE 超全域函數(shù)來讀取它們。 </p> <hr> <h2> 項目：帶有 Cookie 處理的 PHP 表單 </h2> <p>我們將建立一個簡單的應用程式：</p> <ol> <li>允許使用者透過表單提交資訊。 </li> <li>將提交的資料儲存在cookie中。 </li> <li>顯示儲存的cookie資料。 </li> <li>提供刪除 cookie 的選項。 </li> </ol> <hr> <h3> 文件結構 </h3> <p>我們的專案包含以下文件：<br> </p> <pre
