详细介绍mysql巡检脚本的案例代码

下面小编就为大家带来一篇mysql巡检脚本(必看篇)。小编觉得挺不错的，现在就分享给大家，也给大家做个参考。一起跟随小编过来看看吧

如下所示：

初阶PHP Apache MySQL网站设计

初阶PHP Apache MySQL网站设计来自作者多年学习、应用和讲授PHP的经验与体会，是专为学习PHP+MySQL数据库编程人员编与的入门教材。在最后二章设计了2个贴近实际应用的典型案例：留言本系统和论坛系统，每个案例先介绍开发思路、步骤，再给出全部源代码，使所学内容与实际应用紧密结合，特别是论坛系统将全书的案例串讲起来，力求使读者学到最贴近应用前沿的知识和技能。
