轻量级的零配置SQLite基础键值存储，带有过期时间，适用于PHP。

基本上它是一个简单的键值存储，带有过期字段，过期后将删除值。由于它受到Redis的很大影响，实现了一些Redis的有用功能。

稳定版本

使用

<?php 
//include the class
include_once('SQLite_simple_store.php');

//instanceate the class
$s = new SQLite_simple_store('user_table');

//simple set key => value
$s->set('name','oha');

//simple get value by key
echo $s->get('name'); //oha

//set with expiretion time
$s->set('token','asdjjrt788dsfjjj447586',6000);

//update value
$s->set('name','ohad');

//get all keys
var_dump($s->keys());

//set a more complex value
$s->set('user_1',
    array(
        'user_id' =>  1,
        'email'   => 'email@mail.com',
        'meta'    =>  array(
            'user_meta1' => 'some value',
