php基于文件的登录验证，代码如下：

<?php
/**
* 基于文件的登录
* edit by www.
*/
   $authorized = FALSE;

   if (isset($_SERVER['PHP_AUTH_USER']) &&
   isset($_SERVER['PHP_AUTH_PW'])) {
      $authFile = file("./password.txt"); // 密码文件

      foreach ($authFile as $login) {
         list($username, $password) = explode(":", $login);
         $password = trim($password);
         if (($username == $_SERVER['PHP_AUTH_USER']) &&
  ($password == md5($_SERVER['PHP_AUTH_PW']))) {
            $authorized = TRUE;
            break;
         }
      }
   }

   // 验证失败则显示提示框或401错误
   if (! $authorized) {
      header('WWW-Authenticate: Basic Realm="Secret
      Stash"');
      header('HTTP/1.0 401 Unauthorized');
      print('您必须提供正确的凭证!');
      exit;
   }

?>

[2]php实例之基于Cookie的登录表单和获取最后登录时间

1，html部分

<html>
  <head>
  <title>基于cookie的登录表单，密码提交页-www.</title>
  </head>
  <body>
  <form name="forml" method="POST"
  action="/blog_article/CookieBasedPasswordLogin.html">
    <table>
      <tr>
       <td colspan="2" >
         <div align="center"><b>请输入您的密码</b></div>
       </td>
     </tr>
   <tr>>
     <td>
       <div align="right">用户名：</div>
     </td>
     <td>
       <input type="text" name="username">
     </td>
   </tr>
   <tr>
     <td>
       <div align="right">密 码：</div>
     </td>
     <td>
       <input type="password" name="password">
     </td>
   </tr>
   <tr>
     <td colspan="2">
       <center>
         <input type="submit" name="Submit" value="登 录">
       </center>
     </td>
    </tr>
   </table>
  </form>
  </body>
  </html>

2，登录检测页 CookieBasedPasswordLogin.php

<?php
    $now = getdate();
    $storetime= $now["weekday"] . " " . $now["month"] ." " .
    $now["year"] ;
    $storetime.=" Time : ";

    if ($now["hours"] < 10) {
      $storetime.= "0" . $now["hours"];
    } else {
      $storetime.= $now["hours"];
    }

    $storetime.= ":";
    if ($now["minutes"]<10) {
      $storetime.= "0" . $now["minutes"];
    } else {
      $storetime.= $now["minutes"];
    }

    $storetime.= ": ";
    if ($now["seconds"] <10) {
      $storetime.= "0" . $now["seconds"];
    } else {
      $storetime.= $now["seconds"];
    }
    if (isset($data)) {
       $counter=++$data[l];
        setcookie("data[0]",$storetime,time() + (60*60*24));

 setcookie("data[2]",$username,time() + (60*60*24));
        echo "<b><center>Hi " . $data[2] . " !
 !</center></b><br>\n";
        echo "<b><center>最后登录时间 :" .$data[0] .

        echo "<b><center>您已经成功登录。</center></b>";
        echo ("<b><contor>您可以在接下来的24小时内，无须再提供密码均可访问。</center></b>");
   } else {
    if (isset($username) && isset($password)) {

          header($url);
     }else{
          echo "<hl><center>密码验证失败！</center></hl>";
     }
    }
  }

[3]php实例之浏览器中显示密码提示框

来源: 互联网发布时间: 2013-12-24

1，php代码

<?php
/**
* 浏览器 显示密码提示框
* edit by www.
*/
   if (($_SERVER['PHP_AUTH_USER'] != 'specialuser') ||
   ($_SERVER['PHP_AUTH_PW'] != 'secretpassword')) {
      header('WWW-Authenticate: Basic Realm="Secret
      Stash"');
      header('HTTP/1.0 401 Unauthorized');
      print('You must provide the proper credentials!');
      exit;
   }
?>

2，打开浏览器密码对话框和认证用户基于数据库

<?php
   function authenticate_user() {
      header('WWW-Authenticate: Basic realm="Secret Stash"');
      header("HTTP/1.0 401 Unauthorized");
      exit;
   }

   if(! isset($_SERVER['PHP_AUTH_USER'])) {
      authenticate_user();
   } else {
      mysql_connect("localhost","authenticator","secret") or
      die("连接数据库服务器失败!");
      mysql_select_db("gilmorebook") or die("未能连接验证数据库。");

      $query = "SELECT username, pswd FROM user WHERE
      username='$_SERVER[PHP_AUTH_USER]'
                      AND pswd=MD5('$_SERVER[PHP_AUTH_PW]')
        AND
        ipAddress='$_SERVER[REMOTE_ADDR]'";

      $result = mysql_query($query);
      if (mysql_num_rows($result) == 0)
         authenticate_user();
         mysql_close();
      }
?>
