README

A key/value database store using flat files for PHP.

Features include:

Memory efficient
File locking
Caching
Gzip compression
Easy to use

Installation

The easiest way to install Flintstone is via composer. Run the following command to install it.

composer require fire015/flintstone

<?php
require 'vendor/autoload.php';

use Flintstone\Flintstone;

$users = new Flintstone('users', ['dir' => '/path/to/database/dir/']);

Requirements

PHP 7.3+

Data types

Flintstone can store any data type that can be formatted into a string. By default this uses serialize(). See Changing the formatter for more details.

Options

Usage examples

<?php

// Load a database
$users = new Flintstone('users', ['dir' => '/path/to/database/dir/']);

// Set a key
$users->set('bob', ['email' => 'bob@site.com', 'password' => '123456']);

// Get a key
$user = $users->get('bob');
echo 'Bob, your email is ' . $user['email'];

// Retrieve all key names
$keys = $users->getKeys(); // returns array('bob')

// Retrieve all data
$data = $users->getAll(); // returns array('bob' => array('email' => 'bob@site.com', 'password' => '123456'));

// Delete a key
$users->delete('bob');

// Flush the database
$users->flush();

Changing the formatter

By default Flintstone will encode/decode data using PHP's serialize functions, however you can override this with your own class if you prefer.

Just make sure it implements Flintstone\Formatter\FormatterInterface and then you can provide it as the formatter option.

If you wish to use JSON as the formatter, Flintstone already ships with this as per the example below:

<?php
require 'vendor/autoload.php';

use Flintstone\Flintstone;
use Flintstone\Formatter\JsonFormatter;

$users = new Flintstone('users', [
    'dir' => __DIR__,
    'formatter' => new JsonFormatter()
]);

Changing the cache

To speed up data retrieval Flintstone can store the results of get() in a cache store. By default this uses a simple array that only persist's for as long as the Flintstone object exists.

If you want to use your own cache store (such as Memcached) you can pass a class as the cache option. Just make sure it implements Flintstone\Cache\CacheInterface.
