&lt;?
//读取COOKIE的用户名和密码的值即可
if($_COOKIE[&#39;uname&#39;]!=&#39;&#39;){$CKUNAME =  $_COOKIE[&#39;uname&#39;];}
if($_COOKIE[&#39;pwd&#39;]!=&#39;&#39;){$CKPWD =  $_COOKIE[&#39;pwd&#39;];}
echo $CKUNAME;
echo &#39;&lt;br&gt;&#39;;
echo $CKPWD;
?&gt;
&lt;form id=&quot;form1&quot; name=&quot;form1&quot; method=&quot;post&quot; action=&quot;&quot;&gt;
    &lt;input type=&quot;text&quot; name=&quot;uname&quot; id=&quot;uname&quot; value=&quot;&lt;?=$CKUNAME;?&gt;&quot; /&gt; &lt;input
       type=&quot;password&quot; name=&quot;pwd&quot; id=&quot;pwd&quot; value=&quot;&lt;?=$CKPWD;?&gt;&quot; /&gt; &lt;input
       name=&quot;remember&quot; type=&quot;checkbox&quot; value=&quot;1&quot; &lt;? if($CKUNAME!=&#39;&#39;){?&gt;
       checked=&quot;checked&quot; &lt;? } ?&gt; /&gt; 记住我! &lt;input type=&quot;submit&quot; name=&quot;button&quot;
       id=&quot;button&quot; value=&quot;登录&quot; /&gt;
&lt;/form&gt;
&lt;?
//登录，将用户名和密码存入到COOKIE
if($_POST[&#39;button&#39;]!=&#39;&#39;){
    $uname = $_POST[&#39;uname&#39;];
    $pwd = $_POST[&#39;pwd&#39;];
    //如果输入的加密密码和COOKIE中不一样，那么就加密
    if($pwd!=$CKPWD){$pwd = md5($pwd);}
    $remember = $_POST[&#39;remember&#39;];
    if($remember==1){
       setcookie(&quot;uname&quot;, $uname, time()+3600*24*30);
       setcookie(&quot;pwd&quot;, $pwd, time()+3600*24*30);
    }
