“博客迷”（BlogMi）源码阅读[2]

首页面包括的文件源码如下:

文件实现了:

1.打开所有的错误输出.

2.包括了两个文件.

3.定义了一个404页面.

<?php
ini_set("display_errors", "On"); error_reporting(E_ALL);//ini_set — 为一个配置选项设置值
/*error_reporting() 函数规定报告哪个错误[1]  。
该函数设置当前脚本的错误报告级别。
该函数返回旧的错误报告级别。*/
require_once 'tags.php';
require_once 'conf.php';
function mc_404()
{
  header('HTTP/1.0 404 Not Found');
  echo "<h1>404 Not Found</h1>";
  echo "The page that you have requested could not be found.";
  exit();
}
?>

tag.php源码如下:

文件实现了:

1.实现对全局变量转换成HTML实体并返回的函数.

2.定义了主题URL地址.

3.一些内容类型确定函数.

4.各种内容跳转链接地址生成函数.(首页文件中用正则表达式来匹配这些链接地址)

conf.php源码如下:

1.定义全局配置.该配置文件可以通过后台登录修改.管理员帐户密码全是明文的.

<?php
$mc_config = array (
  'site_link' => 'http://127.0.0.1:8080',
  'site_name' => '博客迷',
  'site_desc' => '不需要数据库的迷你博客程序',
  'user_name' => 'admin',
  'user_pass' => '2046',
  'user_nick' => 'BlogMi',
  'comment_code' => '',
)
?>

publish.php源码如下:

1.该文件是用来存放文章信息的.

包含博客的id,标题,标签等.每发表一篇博文就会添加一条信息.

<?php
$mc_posts=array (
  'pxvczn' => 
  array (
    'id' => 'pxvczn',
    'state' => 'publish',
    'title' => 'Hello，World！',
    'tags' => 
    array (
      0 => '妙语',
      1 => '男人',
      2 => '女人',
    ),
    'date' => '2012-04-05',
    'time' => '10:10:10',
    'can_comment' => '1',
  ),
)
?>
