求不用数据库简单的PHP密码验证源码
不用数据将密码直接写到源程序当中是很危险的只要查看源程序就知道密码
<form action="?" method="post">
用户名:<input type="text" name="username"/></br>
密 码:<input type="password" name="pwd" /></br>
<input type="submit" value="登入" /></br>
</form>
<?php
$username='admin';
$pwd='';
if(isset($_POST['username'])){
if( $_POST['username']==$username && $_POST['pwd']==$pwd ){
echo "登入成功！";
}else{
$_POST['pwd']==$pwd ){
echo "登入失败！源码";
}
}
>以上就是源码了，这种要每次重新登入
密码也不安全，源码spring源码经典书籍不过有办法
你重新创建一个php
<?源码php
echo md5("");//你要设置的密码
>进去这个页面他会给出一个md5数据摘要
复制到$pwd
然后把密码对比改为
md5($_POST["pwd"])==$pwd
这种的话别人即使看到源码也不知道密码是什么
求一个：最简单的asp登陆界面代码
<form id="form1" name="form1">
用户名：<input type="text" id="UserName" name="UserName">
密 码：<input type="password" id="PassWord" name="PassWord">
<input type="button" value="提交" onclick="javascript:if
(document.all.UserName.value!='suchen' && document.all.PassWord.value!
='suchen'){ alert('用户名或密码有误!')}else
{ location.href='/ken_fly';}">
</form>
因为你没有数据库的，所以其实用这个就行了，源码开放世界游戏源码不用那么麻烦，源码
把“suchen"和那个/ken_fly改为你想要的源码就行。
呵呵。源码把它复制到别的源码地方比较看得清。这里这个宽度太小，源码不好看！源码
设计的源码p45源码话，要你自己根据你的源码页面设计，在这里我就帮不了你了，源码只能给你源码。菜鸟驿站php源码呵呵!
