<p>直接代码：</p><p>注意：一定要写好数据库保存路径</p>

<?php // sqlite分页类class SqliteDB{public function __construct(){// 初始化数据库，并且连接数据库  数据库配置$this->db = new PDO('sqlite:'.dirname(__FILE__).'\log.db');$this->table_name=$tab;$this->tab_init();}public function tab_init(){# 表初始化,创建表$this->db->exec("CREATE TABLE log(id integer PRIMARY KEY autoincrement,urls varchar(200),ip varchar(200),datetimes datetime default (datetime('now', 'localtime')))");}public function insert($tab_name,$key_list,$value_list){// echo "INSERT INTO ".$tab_name." (".$key_list.") values(".$value_list.")";$result=$this->db->exec("INSERT INTO ".$tab_name." (".$key_list.") values(".$value_list.")");if (!$result) {return false;}// echo "{{{INSERT INTO ".$tab_name." (".$key_list.") values(".$value_list.")}}}}";$res=$this->db->beginTransaction();//事务回gun}public function total($tab_name,$tj='')//求总记录数目{$sth = $this->db->prepare('SELECT  count(id) as c FROM '.$tab_name.'  '.$tj);$sth->execute();$result = $sth->fetchAll();return $result[0]['c'];}public function update(){# 修改}function delete($value=''){# 删除}public function query($tab_name,$tj='')//表名称和条件{$sth = $this->db->prepare('SELECT * FROM '.$tab_name.'  '.$tj);// echo 'SELECT * FROM '.$tab_name.'  '.$tj;$sth->execute();$result = $sth->fetchAll();return $result;}}// $db=new SqliteDB();// $res=$db->insert('log','ip,urls,datetimes','"127.0.0.1","www.baidu.com","2012-12-12 00:00:00"');//添加案例// $res=$db->query('log');//查询案例// $res=$db->total('log');//查询案例// print_r($res);// foreach ($res as $key => $row) {// echo  $row['urls'];// }?>
