php sqlite類

 

php5.3開始,默認開啓了sqlite擴展,高於此版本的可以直接使用,直接上代碼.

<?php
/***
//應用舉例
require_once('cls_sqlite.php');
//創建實例
$DB=new SQLite('blog.db'); //這個數據庫文件名字任意
//創建數據庫表。
$DB->query("create table test(id integer primary key,title varchar(50))");
//接下來添加數據
$DB->query("insert into test(title) values('泡菜')");
$DB->query("insert into test(title) values('藍雨')");
$DB->query("insert into test(title) values('Ajan')");
$DB->query("insert into test(title) values('傲雪藍天')");
//讀取數據
print_r($DB->getlist('select * from test order by id desc'));
//更新數據
$DB->query('update test set title = "三大" where id = 9');
