pbootcms模板自动清理runtime缓存的方法

// 测试扩展单个标签
private function test()
{
$this->content = str_replace('{pboot:userip}', get_user_ip(), $this->content);
}
添加清理函数： 在 test() 函数下面添加如下代码：
// 自动会话清理脚本
public function clean_session()
{
check_dir(RUN_PATH . '/archive', true);
$data = json_decode(trim(substr(file_get_contents(RUN_PATH . '/archive/session_ticket.php'), 15)));
if ($data->expire_time && $data->expire_time < time()) {
ignore_user_abort(true);
set_time_limit(7200);
ob_start();
ob_end_flush();
flush();
$rs = path_delete(RUN_PATH . '/session');
if ($rs) {
$data->expire_time = time() + 60 * 60 * 24; // 下一次清理时间
create_file(RUN_PATH . '/archive/session_ticket.php', "<?php exit();?>".json_encode($data), true);
}
} else {
$data->expire_time = time() - 60 * 60 * 24; // 初始化清理时间
create_file(RUN_PATH . '/archive/session_ticket.php', "<?php exit();?>".json_encode($data), true);
}
}

<?php
if (!isset($_GET['no_clean'])) {
include_once APP_PATH . '/home/controller/ExtLabelController.php';
$controller = new \app\home\controller\ExtLabelController();
$controller->clean_session();
}
?>

<?php exit();?>
{"expire_time":<?php echo time() - 60 * 60 * 24; ?>} // 初始化清理时间
