PHP实现的简单操作SQLite数据库类与用法示例

<&＃63;php
/***
//应用举例
require_once('cls_sqlite.php');
//创建实例
$DB=new SQLite('blog.db'); //这个数据库文件名字任意
//创建数据库表。
$DB->query("create table test(id integer primary key,title varchar(50))");
//接下来添加数据
$DB->query("insert into test(title) values('泡菜')");
$DB->query("insert into test(title) values('蓝雨')");
$DB->query("insert into test(title) values('Ajan')");
$DB->query("insert into test(title) values('傲雪蓝天')");
//读取数据
print_r($DB->getlist('select * from test order by id desc'));
//更新数据
$DB->query('update test set title = "三大" where id = 9');
