thinkphp实现清除缓存

dedecms有清除缓存的功能于是下功夫去研究了一下,结果弄的我云里雾里,嗨....结果自己在网上查了一下,按照网站的自己写了一个清除缓存的功能.

tp执行代码:

//是获取要清楚的目录和目录所在的绝对路径
public function cache(){
////前台用ajax get方式进行提交的,这里是先判断一下
if($_POST['type']){
//得到传递过来的值
$type=$_POST['type'];
//将传递过来的值进行切割,我是已“-”进行切割的
$name=explode('-', $type);
//得到切割的条数,便于下面循环
$count=count($name);
//循环调用上面的方法
for ($i=0;$i<$count;$i++){
//得到文件的绝对路径
$abs_dir=dirname(dirname(dirname(dirname(__FILE__))));
//组合路径
$pa=$abs_dir.&#39;\index\Runtime\\&#39;;
$runtime=$abs_dir.&#39;\index\Runtime\~runtime.php&#39;;
if(file_exists($runtime))//判断 文件是否存在
{
unlink($runtime);//进行文件删除
}
//调用删除文件夹下所有文件的方法
$this->rmFile($pa,$name[$i]);
}
//给出提示信息
$this->ajaxReturn(1,&#39;清除成功&#39;,1);
}else{
$this->display();
}
}
public function rmFile($path,$fileName){//删除执行的方法
//去除空格
$path = preg_replace(&#39;/(\/){2,}|{\\\}{1,}/&#39;,&#39;/&#39;,$path);
//得到完整目录
$path.= $fileName;
//判断此文件是否为一个文件目录
if(is_dir($path)){
//打开文件
if ($dh = opendir($path)){
//遍历文件目录名称
while (($file = readdir($dh)) != false){
//逐一进行删除
unlink($path.&#39;\\&#39;.$file);
}
//关闭文件
closedir($dh);
}
}
}
tp:前台代码(有点简陋哦)
