AnyDataset

AnyDataset is a powerful data source abstraction layer for PHP that provides a simple and consistent interface to access different data sources. With AnyDataset, you can work with various data formats and storage systems using the same programming interface.

It is the core component of the Anydataset project, an agnostic data source abstraction layer for PHP.

Key Features

• Unified Interface: Access different data sources (databases, arrays, XML, JSON, etc.) using the same interface
• Flexible Iteration: Multiple ways to iterate through your data
• Powerful Filtering: Filter your data using a SQL-like syntax
• Data Transformation: Convert between different formats (JSON, XML, arrays)
• Validation: Validate your data against rules
• Extensible: Create your own data source implementations

Quick Start

Installation

composer require "byjg/anydataset"

Basic Usage

<?php
# Create a dataset
$dataset = new \ByJG\AnyDataset\Core\AnyDataset("example");

# Get an iterator
$iterator = $dataset->getIterator();

# Iterate over the results
foreach ($iterator as $row) {
    print_r($row->toArray());
}

Example Code Snippets

Filtering Data

<?php
$filter = new \ByJG\AnyDataset\Core\IteratorFilter();
$filter->addRelation("field1", \ByJG\AnyDataset\Core\Enum\Relation::EQUAL, 10);
$iterator = $dataset->getIterator($filter);

Using Formatters

<?php
$formatter = new XmlFormatter($anydataset->getIterator());
$formatter->raw();                           // Return a DOM object
$formatter->toText();                        // Return the XML as a text
$formatter->saveToFile("/path/to/file.xml"); // Save the XML Text to a file
