小编Fai*_*ool的帖子

我正在尝试在PHP和mySQL中创建线程消息传递系统。我的消息表如下

SELECT `es_id`, `es_fid`, `es_tid`, `es_subject`, `es_message`, `es_onstamp`, `es_msg_read`, `es_f_del`, `es_t_del`, `threadid` FROM `esb2b_messages`

在这张桌子

es_id = primary key for the table.
es_fid = This field store the from user id.
es_tid = This field store the to user id.
es_subject = This field store the subject of message.
es_message = This field store the body of message.
es_onstamp = This field store the time stamp.
es_msg_read = This field store if receiver open the message.
es_f_del = This field …

我正在尝试制作开源缓存库.库的目的是提供将变量(可以是对象,可以是数组,可以是任何东西)存储到文件中然后在调用时检索它的方法.(通常那些变量值是大量数据库查询和计算的结果).

该项目的基本目标是实践面向对象的设计原则,称为实体.

如果任何人可以指出我违反固体原则的地方以及如何解决它

我完全理解stackoverflow不是代码编写服务,但是我正在使这个库开源,所以它会使我们的社区受益.

所以这是我的文件结构.

我是UML的新手,所以如果发现任何错误,请忽略

这是类的实现.

高速缓存

namespace library\pingle\cache;

use library\pingle\cache\config\CacheConfigurator;
use library\pingle\cache\file\FileHandler;

/**
 * @property CacheReader $cache_reader
 * @property CacheWriter $cache_write

Class Cache {

    private $config;
    private $file_hander;
    private $cache_reader;
    private $cache_write;
    private $cache_directory;
    private $cache_kept_days;
    private $cache_file_prams;
    private $function_name;
    private $file_path;

    function __construct(CacheConfigurator $config) {
        $this->file_hander = new FileHandler();
        $this->config = $config;
        list($this->cache_directory, $this->function_name, $this->cache_kept_days, $this->cache_file_prams) = $this->config->getConfig();
        $this->file_path = $this->generateFileName($this->cache_file_prams);
    }

        if (is_null($this->cache_reader)) {
            $this->cache_reader = new CacheReader($this->file_hander);
        }
        return $this->cache_reader->readCache($this->file_path); …

您好，在此实例中，数据库安全组对所有入站流量（所有端口 - 所有源）开放。

我还可以在 mysql 工作台或 Datagrip 中很好地连接到数据库，这肯定会使用 jdbc 连接字符串。
