PHP博客（1） 数据库与界面设计的解决办法

这篇文章主要为大家详细介绍了PHP博客（1） 数据库与界面设计的简单示例，具有一定的参考价值，可以用来参考一下。

感兴趣的小伙伴，下面一起跟随php教程的小玲来看看吧！

代码如下:

 
<?php
/*   php教程 www.512Pic.com   */
 
ini_set( "display_errors", true ); 
date_default_timezone_set( "Asia/Shanghai" ); 
// root and direcotry separate 
define('DS', DIRECTORY_SEPARATOR); 
define('ROOT', dirname(dirname(__FILE__))); 

// database information 
// need hash 
define( "DB_USERNAME", "****" ); 
define( "DB_PASSWORD", '*****' ); 
define( "DB_NAME", "blog" ); 

// important directory 
define( "CLASS_PATH", "classes" ); 
define( "TEMPLATE_PATH", "templates" ); 

// user imformation 
define( "ADMIN_USERNAME", "admin" ); 
define( "ADMIN_PASSWORD", '$2a$08$wim8kpwHhAKa6MBSsGUMGOYfjkU1xvRKd4Fxwal.wj8dqFboCVSFawim8kpwHhAKa6MBSsGUMGO'); 
// hash and verified the password 
function hasher($info, $encdata = false){ 
$strength = "08"; 
//if encrypted data is passed, check it against input ($info) 
if ($encdata) { 
if (substr($encdata, 0, 60) == crypt($info, "$2a$".$strength."$".substr($encdata, 60))) { 
return true; 
}else { 
return false; 
} 
} else { 
//make a salt and hash it with input, and add salt to end 
$salt = ""; 
for ($i = 0; $i < 22; $i++) { 
$salt .= substr("./ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789", mt_rand(0, 63), 1); 
} 
//return 82 char string (60 char hash & 22 char salt) 
return crypt($info, "$2a$".$strength."$".$salt).$salt; 
} 
} 

function __autoload($className) { 
if (file_exists(ROOT . DS . 'classes' . DS . strtolower($className) . '.class.php')) { 
require_once(ROOT . DS . 'classes' . DS . strtolower($className) . '.class.php'); 
} else { 
/* Error Generation Code Here */ 
} 
} 

代码如下:

 
<?php
/*   php教程 www.512Pic.com   */
 
require_once( "config/config.php" ); 
session_start( ); 
$action = isset( $_GET['action'] ) ? $_GET['action'] : ""; 
$username = isset( $_SESSION['username'] ) ? $_SESSION['username'] : ""; 

if ( $action != "login" && $action != "logout" && !$username ) { 
login(); 
exit; 
} 

switch( $action ){ 
case "login" : 
login( ) ; 
break; 

case "logout"; 
logout( ); 
break; 

default : 
admin( ); 
break; 
} 

function login( ){ 
$results['pageTitle'] = "Login Form"; 
// handle login 
if( isset( $_POST['login'] ) ){ 
// we simple verify it from constant variable 
// if we need to verify the user from database , do this later 
// $user = new User ; 
// $user->isValidateUser( $name, $password ); 

if ( $_POST['username'] == ADMIN_USERNAME && $_POST['password'] == hasher($_POST['password'], ADMIN_PASSWORD ) ){ 
// register a session data 
$_SESSION['username'] = ADMIN_USERNAME ; 
// location to admin page 
header( "Location: index.php"); 
} else { 
// Login failed: display an error message to the user 
$results['errorMessage'] = "Incorrect username or password. Please try again."; 
require( TEMPLATE_PATH . "/loginForm.php" ); 
} 
} else { 
require( TEMPLATE_PATH . "/loginForm.php" ); 
} 
} 

function admin( ){ 
$results['pageTitle'] = "Administrator Page"; 
require( TEMPLATE_PATH . "/admin.php" ); 
} 

function logout( ){ 
$results['pageTitle'] = "Login Page"; 
unset( $_SESSION['username'] ); 
header( "Location: index.php "); 
}
