ThinkPHP清除缓存/删除文件夹上所有文件
ThinkPHP清除缓存/删除文件夹下所有文件
今天做了一个ThinkPHP清除缓存功能,在网上开了一下有一个比较简单的写法但是那个是ThinkPHP内置的一个类,我找了半天没找到这个类,气死我了 于是就用php删除文件夹下所有文件这个方法来达到清除缓缓存的的功能,废话不多说粘上代码:
/*此方法为公共方法用来删除某个文件夹下的所有文件
* $path为文件的路径
* $fileName文件夹名称
* */
public function rmFile($path,$fileName){
//去除空格
$path = preg_replace('/(\/){2,}|{\\\}{1,}/','/',$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($path.'\\'.$file);
}
//关闭文件
closedir($dh);
}
}
}
//一对一删除缓存
public function cache(){
//前台用ajax get方式进行提交的,这里是先判断一下
if($_GET['type']){
//获取提交过来的值(也就是要删除的文件夹名称)
$type=$_GET['type'];
//获取文件的绝对路径
$abs_dir=dirname(dirname(dirname(dirname(__FILE__))));
//与要删除的文件夹里的文件进行组合
$pa=$abs_dir.'\Admin\Runtime\\';
//调用上面写好的方法
$this->rmFile($pa,$type);
//返回提示信息
$this->ajaxReturn(1,'清除成功',1);
}else{
$this->display();
}
}
//一键清除所有缓存
public function allrun(){
////前台用ajax get方式进行提交的,这里是先判断一下
if($_GET['type']){
//得到传递过来的值
$type=$_GET['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
//得到文件的绝对路径
$abs_dir=dirname(dirname(dirname(dirname(__FILE__))));
//组合路径
$pa=$abs_dir.'\Admin\Runtime\\';
//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,'清除成功',1);
}else{
$this->display();
}
}
前台页面很简单 在这里就给出重要的代码
html文件
//这个是ajax get方式提交
//一键清除所有
