ThinkPHP5.1 清除缓存
第一种方法
在基类控制器里，写上
clear()方法，到时候用于调用,在也不是JS里alert('清除缓存了')
当然，5.1取消了CACHE_PATHTEMP_PATH常量，所以要定义这些缓存目录，还需引入use think\facade\Env
// 我是直接按照文档，设置了2个变量来存储缓存目录，当然还可以在配置文件中进行配置，然后通过config获取
public function clear(){
$CACHE_PATH = Env::get('runtime_path') . 'cache/';
$TEMP_PATH = Env::get('runtime_path'). 'temp/';
if (delete_dir_file($CACHE_PATH) && delete_dir_file($TEMP_PATH)) {
return json(["code"=>1,"msg"=>"清除缓存成功"]);
} else {
return json(["code"=>0,"msg"=>"清除缓存失败"]);
}
}这个时候发现
delete_dir_file()函数未定义，我们去公共函数里进行定义并写出来:
由于5.1 没有DS常量了，所以选用DIRECTORY_SEPARATOR来代替
common.php:
/**
* 循环删除目录和文件
* @param string $dir_name
* @return bool
*/
function delete_dir_file($dir_name) {
$result = false;
if(is_dir($dir_name)){
if ($handle = opendir($dir_name)) {
while (false !== ($item = readdir($handle))) {
if ($item != '.' && $item != '..') {
if (is_dir($dir_name . DIRECTORY_SEPARATOR. $item)) {
delete_dir_file($dir_name . DIRECTORY_SEPARATOR. $item);
} else {
unlink($dir_name . DIRECTORY_SEPARATOR. $item);
}
}
}
closedir($handle);
if (rmdir($dir_name)) {
$result = true;
}
}
}
return $result;
}第二种方法
public function delCache() {
if (Dir::del(Env::get('runtime_path').'cache/') {
$data = ['status' => 1, 'info' => '缓存删除成功'];
} else {
$data = ['status' => 0, 'info' => '缓存删除失败];
}
return json($data);
}这个需要一个
Dir类
