这是本人根据自己学习PHP技术页面静态化的过程所写的学习笔记,希望能够对大家有所帮助。


1、真静态化的方案

(1)使用PHP自身的缓存机制

a.配置PHP配置文件php.ini

         display_errors= On

         output_buffering= Off

         error_reporting= E_ALL | E_STRICT

2、常用函数

(1)ob_get_contents()可以获取output_buffering的内容

(2)ob_clean()可以清空output_buffering的内容

(3)ob_end_clean()可以关闭output_buffering同时清空output_buffering的内容

(4)ob_end_flush()可以把ob缓存的内容输出并关闭ob

(5)ob_flush()可以把ob缓存的内容输出,但是不关闭ob

(6)flush()可以输出程序缓存的内容

(7)str_repeat("0",1024)可以重复输出1024个0

test2.php(以上函数的实际应用)

<?php //开启缓存【通过php.ini也可以开启缓存】
	ob_start();
    echo "yyy";
	header("content-type:text/html;charset=utf-8");
	echo "hello";
	//ob_clean()可以清空output_buffering的内容
	//ob_clean();
	//ob_end_clean()可以关闭output_buffering同时清空output_buffering的内容
	// ob_end_clean();
	//ob_end_flush()可以把ob缓存的内容输出并关闭ob
	// ob_end_flush();
	//ob_flush()可以把ob缓存的内容输出,但是不关闭ob
	// ob_flush();
	echo str_repeat("0", 1024);
	echo "yyy";
	// header("content-type:text/html;charset=utf-8");
	
	//ob_get_contents()可以获取output_buffering的内容
	// $content = ob_get_contents();
	// file_put_contents("d:/log.txt", $content);
?>
Copy after login

3、静态化页面适用于大型网站

(1)访问量巨大

(2)多次查询结果相同的网站(比如新闻网站)

(3)实时性要求不高的网站

4、页面静态化传统解决方案的基本思路

(1)第一次访问页面时,从数据库查询出所需数据,组成网页

(2)使用ob的缓存机制,把内容缓存到html页面

(3)以后访问此页面时,直接访问html页面
