主要是在登录和退出的时候,设置cookies。来保存登录和安全退出

1:在登录页面设置

//设置cookies的值
_setcookies($_rows['tg_username'], $_rows['tg_uniqid'],$_clean['time']);
_location(null,'index.php');

Copy after login

第二步:生成cookie,

/**
 * _setcookies
 * @param unknown $_username
 * @param unknown $_uniqid
 */
function _setcookies($_username,$_uniqid,$_time){
  setcookie('username',$_username);
  setcookie('uniqid',$_uniqid);
  switch ($_time) {
    case '0' : // 设置浏览器进程
      setcookie ( 'username', $_username );
      setcookie ( 'uniqid', $_uniqid );
      break;
    case '1' : // 一天的进程
      setcookie ( 'username', $_username, $_time () + 86400 );
      setcookie ( 'uniqid', $_uniqid, $_time () + 86400 );
      break;
    case '2' : // 一周的进程
      setcookie ( 'username', $_username, $_time () + 604800 );
      setcookie ( 'uniqid', $_uniqid, $_time () + 604800 );
      break;
    case '0' : // 一个月的进程
      setcookie ( 'username', $_username, $_time () + 2592000 );
      setcookie ( 'uniqid', $_uniqid, $_time () + 2592000 );
      break;
  }
}

Copy after login

第三步:登录状态中设置

//登录的情况,就是防止登陆后通过在浏览器中直接连接再次登录
function _login_state(){
  if (!isset($_COOKIE['username'])) {
    _alert_back("登录状态无法就行本操作!");
  }
}

//删除cookies
function _unsetcookies(){
  setcookie('username','',time()-1);
  setcookie('uniqid','',time()-1);
  _session_destroy();//删除session
  _location(null,'index.php'); //做跳转
}

Copy after login

第四步在登录页面和退出页面加上

//登录状态
  _login_state();
Copy after login

显示数据的二个方法:在数据配置文件中配置,我的是mysql.func.php

/**
 * _fetch_array 只能获取一条数据组
 * @param $_sql
 */

function _fetch_array($_sql) {
  return mysql_fetch_array(_query($_sql),MYSQL_ASSOC);
}
/**
 * _fetch_array_list可以返回指定数据集的所有数据
 * @param unknown $_result
 * @return multitype:
 */
function _fetch_array_list($_result){
  return mysql_fetch_array($_result,MYSQL_ASSOC);
}

Copy after login

最后在页面中赋值

//从数据库里提取数据获取结果集
//我们必须每次重新读取结果集,而不是从新去执行SQL语句。
$_result = _query("SELECT tg_username,tg_sex,tg_face FROM tg_user ORDER BY tg_reg_time DESC");

<&#63;php while (!!$_rows = _fetch_array_list($_result)) {&#63;>
  <dl>
    <dd class="user"><&#63;php echo $_rows['tg_username']&#63;><&#63;php echo $_rows['tg_sex']&#63;></dd>
    <dt><img  src="<&#63;php echo $_rows['tg_face']&#63; alt="PHP中COOKIES使用示例_PHP" >" alt="" /></dt>

Copy after login
