Description

This class can manage database of mixed values (atomic values, arrays, objects) named "nodes", stored in record files.

It can create records that are stored in node files of a given schema directory.

Each node is serialized before storing the values in a file. Node files have a named defined by a identifier. Nodes may also reference other nodes in different schema directories.

The class may also search for nodes that match conditions, check if a node exists, update, delete and rename nodes already stored in record files, lock node files to prevent changes, get, add and remove node references, check if a schema directory exists, create, rename and delete schema directories.

Many PHP applications use relational databases to store and retrieve application information by connecting to SQL database servers.

Alternatively applications can also store information in file base databases that do not require the use of SQL, the so called noSQL databases.

This class provides a pure PHP implementation of a noSQL database that stores and retrieves information in files.

It provideds features to avoid problems caused by concurrent accesses such as the use of proper file locking, among other the non-trivial file database access features.

Div PHP Nodes 1.3

No-SQL Database System for PHP

Library for storage relational and serialized data using only PHP. The database can be divided into schemas. The objects (nodes) can be indexed for full text search and fast lookup.

Introduction

Many PHP applications use relational databases to store and retrieve application information by connecting to SQL database servers.

Alternatively applications can also store information in file base databases that do not require the use of SQL, the so called noSQL databases.

This class provides a pure PHP implementation of a noSQL database that stores and retrieves information in files.

It provides features to avoid problems caused by concurrent accesses such as the use of proper file locking, among other the non-trivial file database access features.

Description

This class can manage database of mixed values (atomic values, arrays, objects) named "nodes", stored in record files. It can create records that are stored in node files of a given schema directory.

Each node are serialized before storing the values in a file. Node files have a named defined by a identifier. Nodes may also reference other nodes in different schema directories.

The class may also: - search for nodes that match conditions, - check if a node exists, - update, delete and rename nodes already stored in record files, - lock node files to prevent changes - get, add and remove node references, - check if a schema directory exists, - create, rename and delete schema directories. - iterate each node with closure function - index the node's content for full text search

Basic usage

<?php

include 'divNodes.php';
$db = new divNodes("database/contacts");

$id = $db->addNode(array(
    "name" => "Peter",
    "age" => 25
));

$db->setNode($id, array(
    "email" => "peter@email.com",
    "phone" => "+1222553335"
));

$contact = $db->getNode($id);

$db->delNode($id);
