pear auth를 기반으로 로그인 인증코드 구현

/**
  @文件 yz.php
  @site http://bbs.it-home.org
*/
require_once('Auth.php');
function show_login_form () {
echo '
username:
password:

' ;
}
$options=array('dsn'=>'mysql://root:1@localhost/zs',
'table'=>'users',
'usernamecol'=>'user_name',
'passwordcol'=>'user_passwd',
'cryptType'=>'',
'db_fields'=>'*',
);
$auth=new Auth('DB',$options,'show_login_form');
?>




$auth->start();
if($auth->checkAuth()){
echo "ok";
echo "";
echo "add";
}else {
echo "error";
}
//$auth->setSessionName($auth->getAuthData('user_name'));
?>

二、yzh.php 传递登录后的session

function back(){
echo 'back';
}
require_once('Auth.php');
$auth=new Auth('DB',$option,'back');
$auth->start();
if($auth->checkAuth())
{
echo "this is a session page,welcome ";
echo "{$auth->getUserName()}";
}
?>
