本文執行個體講述了php使用cookie儲存使用者登入的使用者名稱的方法。分享給大家供大家參考。具體實現方法如下：
使用者登入檔案：login.php
代碼如下:
<html><head><title>使用者登入</title></head><body><?phpfunction getCookieUsername(){ if(empty($_COOKIE['username'])){ return ""; }else{ return $_COOKIE['username']; }}?><form action="admin.php" method="post">使用者名稱：<input type="text" name="username" value="<?php echo getCookieUsername(); ?>"><br />密碼：<input type="password" name="pwd"><br />是否儲存使用者名稱：<input type="checkbox" name="yes"><br /><input type="submit" name="sub" value="登入"></form></body></html>
後台檔案：admin.php
代碼如下:
<?phpif(!empty($_POST['sub']) && $_POST['username']=="admin"){ echo "歡迎".$_POST['username']." 登入成功"; if(!empty($_POST['yes'])){ setCookie("username",$_POST['username'],time()+3600*24*30); }else{ setCookie("username","",time()-10); }}else{ echo "你的帳號錯誤，請重新輸入<br />";}echo "<a href='login.php'>返回登入頁面</a>";?>Start building with 50+ products and up to 12 months usage for Elastic Compute Service
