若未安装sqlite扩展,使用安装:sudo apt-get install php7.4-sqlite

<?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');
