ob_start 打开输出控制缓冲（要求php开启缓存，在php配置文件php.ini文件中可以设置 output_buffering = on）
ob_get_contents 返回输出缓冲区内容
ob_clean 清空（擦掉）输出缓冲区
ob_get_clean 得到当前缓冲区的内容并删除当前输出缓冲区
php生成文件的函数 file_put_contents('文件路径','文件内容')。（当然php中还有其他写文件的方法，如fwrite）
看demo
db.php 链接数据库类（自己链接数据库）
<?php /*** 数据库连接封装*/class Db {//存储类的实例的静态成员变量private static $_instance;//数据库链接静态变量private static $_connectSource;//连接数据库配置private $_dbConfig = array('host' => '127.0.0.1','user' => 'root','password' => 'root','database' => 'test');private function __construct() {}/*** 实例化*/public static function getInstance() {//判断是否被实例化if(!(self::$_instance instanceof self)) {self::$_instance = new self();}return self::$_instance;}/*** 数据库连接*/public function connect() {if(!self::$_connectSource) {//数据库连接// @ 符号可以取消警告提示self::$_connectSource = @mysql_connect($this->_dbConfig['host'],$this->_dbConfig['user'],$this->_dbConfig['password']);if(!self::$_connectSource) {//抛出异常处理throw new Exception('mysql connect error ');}//选择一款数据库mysql_select_db($this->_dbConfig['database'], self::$_connectSource);//设置字符编码mysql_query("set names UTF8", self::$_connectSource);}//返回资源链接return self::$_connectSource;}}?>
<?php //1、连接数据库，然后从数据库里面获取数据//2、把获取到的数据填充到模板文件里面//3、需要把动态的页面转化为静态页面，生成纯静态化文件if(is_file('index.html') && (time() - filemtime('index.html')) < 10) { //设置缓存失效时间require_once('index.html');} else {require_once('db.php');$connect = Db::getInstance()->connect();$sql = "SELECT * FROM news WHERE `category_id` ORDER BY id DESC LIMIT 5";$result = mysql_query($sql, $connect);$news = array();while($row = mysql_fetch_array($result)) {$news[] = $row;}// echo '<pre>';// print_r($news);// die;ob_start(); //开启缓存区//引入模板文件require_once('./2.php'); //动态文件 singwa.php界面同样进过缓冲区// echo ob_get_contents();// die;file_put_contents('index.html', ob_get_contents());/*if(file_put_contents('index.shtml', ob_get_clean())) {echo 'success';} else {echo 'error';}*/}?>
