基于pear auth实现的登录验证代码

/**
  @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()}";
}
?>
