php的unlink()函数删除上级目录文件注意事项分享 不指定

php的unlink()函数删除上级目录文件注意事项分享
unlink()删除目录无效吗？
新手比较容易犯的错误，unlink()函数默认的权限只在本目录及子目录，删除上级目录文件，需要改变当前位置，删除后再切换回来。 
如下示例

<?php
    $old = getcwd();  //当前目录
    chdir($path_to_file);   //切换到工作目录
    unlink($filename);   //删除文件
    chdir($old);  //切换到原目录   
?>

ThinkPHP3的缓存技术file分享(网络收藏) 不指定

ThinkPHP3的缓存技术file分享by itlife365.com begin
如果没有缓存的网站是百万级或者千万级的访问量，会给数据库或者服务器造成很大的压力，通过缓存，大幅减少服务器和数据库的负荷。假如我们 把读取数据的过程分为三个层，第一个是访问层，第一个是缓存层，第三个是数据库存取层。如果没有缓存层，访问层是直接从数据库存取层读取数据，而设置缓存 后，访问层不再是直接在数据库存取层读取，而是从缓存层读取数据。
我们做个简单的对比，假设一个页面，在一个小时可被访问100万次，如 果这个页面每次被访问的时候，都直接读取数据库后再编译生成，在一个小时内将会重复性的生成100万次；而如果这个页面被周期性的缓存10分钟，也就是每 间隔10分钟缓存数据才会被生成一次，一个小时内只会被生成6次，两种方式一对比，效果明显，两种比较下服务器负荷的压力比差别十几万倍以上，缓存技术将 使得网站负载在高峰期游刃有余。kyrzy.com 可以让转运的网站
 
thinkphp的缓存方式有许多种，如File、Apachenote、Apc、Eaccelerator、Memcache、Shmop、Sqlite、Db、Redis和Xcache,现在我来说一下File缓存。
Thinkphp缓存文件的配置
 Home是我建立的前台项目，在Home\Conf\config.php找到缓存的配置文件，配置如下:

<?php
/**
 * 配置文件
 */
 return array(
 'DB_TYPE'=>'mysql',
 'DB_HOST'=>'127.0.0.1',
 'DB_NAME'=>'itlife365',
 'DB_USER'=>'thinphp', //自己修改
 'DB_PWD'=>'123456',
 'DB_PORT'=>'3306',
 'DB_PREFIX'=>'kyrzy_',//kyrzy.com 可以让转运
 'DATA_CACHE_TYPE'=>'file',//设置缓存方式为file
 'DATA_CACHE_TIME'=>'600',//缓存周期600秒
);
?>
thinkphp cache
控制器Thinkphp缓存函数的使用
在thinkphp中，我喜欢使用快捷缓存函数S()进行缓存; 其用法如下:
 S('data',$Data);//使用data标识缓存$Data数据
 S('data',$Data,600);// 缓存$Data数据600秒
 $Data = S('data');// 获取缓存数据
 S('data',NULL);// 删除缓存数据
 
下面是是前台项目控制器的完整代码
<?php
// 本类由系统自动生成，仅供测试用途
class IndexAction extends Action{
    public function index(){
      //如果有缓存，则读取缓存数据
      //如果没有缓存，则读取数据库当中的数据放入缓存
      $lists=S('lists');
            if(empty($lists)){
        $news=M('news');
        $lists=$news->select();
        S('lists',$lists,600);
        echo '这是直接读取数据库的数据';
         }
      dump($list);
访问http://127.0.0.1/Home/index.php/Index/index 输出:
 
这是直接读取数据库的数据
array(10) {
[0] => array(12) {
["id"] => string(1) "1"
["catid"] => string(2) "13"
["title"] => string(4) "thinkphp的缓存技术"
["content"] => string(8) "thinkphp的缓存技术"
["tags"] => string(4) "缓存"
["thumb"] => string(0) ""
["description"] => string(7) "thinkphp的缓存技术"
["inputtime"] => string(10) "1348370202"
["posid"] => string(1) "1"
["ord"] => string(1) "2"
["hits"] => string(1) "1"
["status"] => string(1) "1"
}
...
 
说明，第一次运行时，会打印出如上面所示信息，刷新一下页面后，少了“ 这是直接读取数据库的数据"，说明读取的是先前生成的缓存数据。

使用thinkphp3.1页面默认编码GB2312，乱码，查看编码改为UTF-8，正常显示有关问题解决经验分享 不指定

使用thinkphp3.1页面默认编码GB2312，乱码，查看编码改为UTF-8，正常显示有关问题解决经验分享

今天使用thinkphp 3.1开发的时候遇到一个很奇怪的问题,页面返回乱码，需要通过浏览器点击查看->编码->改为UTF-8才能正常显示。
查看模版代码的页面head属性里面已经设置成GB2312编码,但是清空缓存重新使用浏览器默认时还是乱码，默认显示UTF-8
这个问题纠结了很久,网上说有可能是文件生成时本身的编码所致。
通过记事本或者UE重新生成文件并自动字符集编码在生成文件时就选定好UTF-8编码的，然后再将代码黏贴进去，网上说问题可以解决，但是我试了下还是不行。
后面通过F12 查看了一下，是服务器返回的时候响应表头context-type还是:text/html;charset=utf-8 ；虽然响应的正文是:
<meta http-equiv="content-type" content="text/html;charset=gb2312"> 但是最终显示处理的还是乱码。
知道问题的所在了，需要在服务端返回给客户端浏览器的时候指定编码。通过conf.php添加配置项'DEFAULT_CHARSET'=>'gbk'问题解决了
截图如下:


。
响应的设置

同时我的数据库前端数据库的链接配置串是'DB_CHARSET'=>'gbk'




然后发现一个问题，php 中，我的表设置的是utf-8的字符集，后台录入文字的时候conf.php的链接字符串配置的是
'DB_CHARSET'='utf8'// thinkphp的默认配置
'DEFAULT_CHARSET' 没有设置，听说默认的就是utf8
'页面的字符集设置为'<meta http-eqiv="context-type" content="text/html;charset=utf-8" 
后台页面显示正常，功能正常

前台就是不一样了。
录入文字的时候conf.php的链接字符串配置的是
'DB_CHARSET'='gbk'// thinkphp的默认配置utf8
'DEFAULT_CHARSET'='gbk' 没有设置，听说默认的就是utf8
'页面的字符集设置为'<meta http-eqiv="context-type" content="text/html;charset=gb2312" 
前台功能也正常了。不信您也访问看看：
http://kyrzy.com/article/1.html
所以感觉和数据库的表字符集设置没有关系；

我本地客户端分布建了两张表两种字符集的。都可以显示
如下
CREATE TABLE IF NOT EXISTS `ic_testgbk` (

`id` INT( 11 ) NOT NULL AUTO_INCREMENT ,
`name` VARCHAR( 50 ) NOT NULL ,
PRIMARY KEY ( `id` )

) ENGINE = MYISAM DEFAULT CHARSET = gb2312 COMMENT = 'gb2312' AUTO_INCREMENT =2;# MySQL 返回的查询结果为空(即零行)。
--
-- 导出表中的数据 `testgbk`
--
INSERT INTO `ic_testgbk` ( `id` , `name` ) 
VALUES ( 1, '我是gb2312 的' ) ;# 影响列数： 1
-- --------------------------------------------------------
--
-- 表的结构 `testutf8`
--
CREATE TABLE IF NOT EXISTS `ic_testutf8` (

`id` INT( 11 ) NOT NULL AUTO_INCREMENT ,
`name` VARCHAR( 50 ) NOT NULL ,
PRIMARY KEY ( `id` )

) ENGINE = MYISAM DEFAULT CHARSET = utf8 COMMENT = 'utf8' AUTO_INCREMENT =2;# MySQL 返回的查询结果为空(即零行)。
--
-- 导出表中的数据 `testutf8`
--
INSERT INTO `ic_testutf8` ( `id` , `name` ) 
VALUES ( 1, '我是UTF8 S的但是' ) ;# 影响列数： 1
