本文实例讲述了php实现的简单检验登陆类。分享给大家供大家参考。具体如下：
<?php
class checklogin
{
var $name;
var $pwd;
function __construct($username,$password)
{
$this->name=$username;
$this->pwd=$password;
}
function checkinput()
{
global $db;
$sql="select * from tb_manager where name='$this->name' and pwd='$this->pwd'";
$res=$db->query($sql);
$info=$db->fetch_array($res);
if($info['name']==$this->name and $info['pwd']==$this->pwd)
{
$_SESSION[admin_name]=$info[name];
$_SESSION[pwd]=$info[pwd];
echo "<script>alert('登录成功！);window.location.href='index.php';</script>";
}
else
{
echo "<script language='javascript'>alert('登录失败！');history.back();</script>";
exit;
}
}
}
?>
希望本文所述对大家的php程序设计有所帮助。
