使用php 的缓冲区功能和apache的url重写功能实现静态html生成实例

使用Mysql5.0 +php5.0+ apache2.2(开启url重写模块：去掉apache配置文件中LoadModule rewrite_module modules/mod_rewrite.so 前面的#号后重起服务器即可。)
数据库articles的表：
create table article
(
article_id int not null auto_increment,
article_title varchar(200),
article_author varchar(100),
article_datecreate datetime,
article_content text,
article_postip varchar(15),
article_filepath varchar(500),
primary key (article_id)
);
网站目录结构(/表示网站根目录)：
/Article.php
/Articlelist.php
/Createarticle.php
/Article/.htaccess
各文件的内容：
Article.php (用于创建文章，使用fckeditor进行文章编辑)代码如下：
<?php
if(isset($_POST['submit']))
{
$title = $_POST['title'];
$author = $_POST['author'];
$articlecontent = $_POST['FCKeditor1'];
$ip = $_SERVER['REMOTE_ADDR'];
$date = date("YmdHis");
$filename = '/article/' . $date . '.html';
//
$mysqli = @new mysqli('localhost','root','','articles');
if(mysqli_connect_errno()){
echo "数据库连接失败！";
EXIT;
}
$mysqli -> set_charset("utf8");
$query = "insert into article
(article_title,article_author,article_datecreate,article_content,article_postip,article_filepath)
values('$title','$author','$date','$articlecontent','$ip','$filename')";
$mysqli -> query($query);
}
?>

$oFCKeditor->Create() ;
?> </p>
<p><input name="submit" type="submit" value="提交" /></p>

Articlelist.php (文章列表)代码如下：
<?php
$mysqli = @new mysqli('localhost','root','','articles');
if(mysqli_connect_errno()){
echo "数据库连接失败！";
EXIT;
}
$query = 'select article_title,article_filepath from article order by article_id asc';
$mysqli -> set_charset("utf8");
$res = $mysqli -> query($query);
$articlelist = "";
if($res -> num_rows > 0){
for($i = 0 ; $i < $res -> num_rows ; $i++){
$row = $res -> fetch_array(MYSQLI_ASSOC);
$title = $row['article_title'];
$filepath = $row['article_filepath'];
$articlelist .= "<a href=/"".$filepath."/">$title</a><br>";
}
}
?>

<title>文章列表</title>
</head>
<body>
<?php
echo $articlelist;
?>

Createarticle.php（生成静态html,生成的静态html文件在article目录中）代码如下：
<?php
ob_start();
$title = "错误";
$articlebody = "网页不存在,可能已被管理员删除!!!!";
if(isset($_GET['id'])){
$mysqli = @new mysqli('localhost','root','','articles');
if(mysqli_connect_errno()){
echo "数据库连接失败！";
EXIT;
}
$mysqli -> set_charset("utf8");
$filename = "/article/".$_GET['id'].".html";
$query = "select * from article where article_filepath='".$filename."'";
$res = $mysqli -> query($query);
if($res -> num_rows > 0)
{
$row = $res -> fetch_array(MYSQLI_ASSOC);
$title = $row['article_title'];
$articlebody = $row['article_content'];
}
}
?>

$file = fopen(".".$filename,'w'); //打开文件info.txt
fwrite($file,$info); //写入信息到info.txt
fclose($file); //关闭文件info.txt
}
ob_end_flush();//输出全部内容到浏览器
?>
.htaccess(在article目录下，用于实现url重写)代码如下：
rewriteengine on
rewritebase /
RewriteCond %{REQUEST_FILENAME} !-F
RewriteRule ^([0-9]*)/.html createarticle.php?id=$1 [T]
说明：从程序可以看出，文章的第一次请求其实不是真正的html文件，实际上是动态文件createarticle.php文件的执行结果，之后便生成了html文件。
