Homephp教程php手册thinkPHP模型初始化实例分析

这篇文章主要介绍了thinkPHP模型初始化的方法,结合实例形式分析了thinkPHP模型初始化及数据库操作的相关技巧,具有一定参考借鉴价值,需要的朋友可以参考下

/* $dsn = 'mysql://bookman:book123@localhost:3306/Weapons'; $guns_tab = M('guns','',$dsn); $gun1 = $guns_tab ->select(); echo $guns_tab -> getLastSql(); dump($gun1); */ /* $guns_tab = M('guns'); $gun1 = $guns_tab ->select(); echo $guns_tab -> getLastSql(); dump($gun1); */ $guns_tab = new GunsModel(); $gun1 = $guns_tab ->select() -> page('1,1'); echo $guns_tab -> getLastSql(); dump($gun1); $guns_tab -> showInfo(); /* $guns_tab = new DetectModel('guns'); $gun1 = $guns_tab -> select(); echo $guns_tab -> getLastSql(); dump($gun1); $guns_tab -> showInfo(); */

1.脱离配置文件产生的连接方式

$dsn = 'mysql://bookman:book123@localhost:3306/Weapons'; $guns_tab = M('guns','',$dsn); $gun1 = $guns_tab ->select(); echo $guns_tab -> getLastSql(); dump($gun1);

2.依照配置文件连接数据库,表名一定要区分清楚

$guns_tab = M('guns'); $gun1 = $guns_tab ->select(); echo $guns_tab -> getLastSql(); dump($gun1);

3.我有一个自定义的模型,里面实现了自己的业务方法,我还有一个guns的表于是可以这样初始化模型。既可以获取guns表中的数据,还可以使用我自定义模型中的业务方法。

$guns_tab = new DetectModel('guns'); $gun1 = $guns_tab -> select(); echo $guns_tab -> getLastSql(); dump($gun1); $guns_tab -> showInfo();
