ThinkPHP静态缓存简单配置和使用方法详解，thinkphp静态
本文实例讲述了ThinkPHP静态缓存简单配置和使用方法。分享给大家供大家参考，具体如下：
根据ThinkPHP官方手册：ThinkPHP内置了静态缓存类，通过静态缓存规则定义来实现了可配置的静态缓存。
启用静态缓存：
ThinkPHP官方手册写道
要使用静态缓存功能，需要开启HTML_CACHE_ON 参数，并且在项目配置目录下面增加静态缓存规则文件 htmls.php，两者缺一不可。否则静态缓存不会生效。
在配置文件Conf\config.php的array()中加上：
'HTML_CACHE_ON' => true,//开启静态缓存 'HTML_PATH' => '__APP__/html',//静态缓存文件目录，HTML_PATH可任意设置，此处设为当前项目下新建的html目录
静态规则定义：
ThinkPHP官方手册写道
静态规则的定义有三种方式：
Return Array(
'ActionName'=>array('静态规则','静态缓存有效期','附加规则'), //第一种
'ModuleName:ActionName'=>array('静态规则','静态缓存有效期','附加规则'),//第二种
'*'=>array('静态规则','静态缓存有效期','附加规则'),//第三种
…更多操作的静态规则
)
第一种是定义全局的操作静态规则，例如定义所有的read操作的静态规则为：
'read'=>array('{id}','60')
其中，{id} 表示取$_GET['id'] 为静态缓存文件名，第二个参数表示缓存60秒。
第二种是定义某个模块的操作的静态规则，例如，我们需要定义Blog模块的read操作进行静态缓存
'Blog:read'=>array('{id}',-1)第三种方式是定义全局的静态缓存规则，这个属于特殊情况下的使用，任何模块的操作都适用，例如
'*'=>array('{$_SERVER.REQUEST_URI|md5}')
//根据当前的URL进行缓存。
我这里在静态缓存规则文件 htmls.php中写：
<?php
return array(
'getHtml' => array('{:action}', -1),//-1表示永久缓存
);
?>
上面的静态缓存规则表示定义所有的getHtml操作的静态规则为：
'getHtml'=>array('{:action}',-1)
{:action}表示当前操作名为静态缓存文件名。
同样在\Lib\Action\IndexAction.class.php文件中写：
<?php
class IndexAction extends Action{
//在当前项目的html目录下生成getHtml.shtml
public function getHtml() {
header('Content-type:text/html;charset=utf-8');
$this->assign('title', '生成html文件');
$this->assign('info', '生成html文件');
$this->display();
}
}
?>
在\Tpl\default\index\getHtml.html中写：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
<title>{$title}</title>
</head>
<body>
<h2 id="info">{$info}</h2>
</body>
</html>
然后在浏览器中输入：http://127.0.0.1/myApp/index.php/index/getHtml，可看到预期的页面。
刷新页面后，浏览器地址栏会发生变化，如下：
ps:如果用的apache，firefox和opera可能会不支持shtml文件，可以在httpd.conf文件中找到"AddType text/html .shtml","AddOutputFilter INCLUDES .shtml"，分别去掉前面的"#"即可。
