License CircleCI Version Maintenance Ask Me Anything ! PHP Version

Extract, Transform and Load data using PHP. This library provides classes and a workflow to allow you to extract data from various sources (CSV, DB...), one or many, then transform them before saving them in another format.

You can also easily add your custom classes (Extractors, Transformers and Loaders).

Versions and compatibility

  • To benefit from the last features, you need PHP >= 7.4 and use the 2.x version of the library.
  • If you use older versions of PHP: 7.2 <= PHP <= 7.4, use the legacy 1.3.x version (still maintained for bugfixes).

Installation

In your application's folder, run:

composer require wizaplace/php-etl

Example 🚈

In the example below, we will extract data from a csv file, trim white spaces from the name and email columns and then insert the values into the users table:

use Wizaplace\Etl\Etl;
use Wizaplace\Etl\Extractors\Csv;
use Wizaplace\Etl\Transformers\Trim;
use Wizaplace\Etl\Loaders\Insert;
use Wizaplace\Etl\Database\Manager;
use Wizaplace\Etl\Database\ConnectionFactory;

$connexionFactory = new ConnectionFactory();
$manager = new Manager($connexionFactory);
$etl = new Etl();
$extractor = new Csv();
$transformer = new Trim();
$loader = new Insert($manager);

$etl->extract($extractor, '/path/to/users.csv')
    ->transform(
        $transformer,
        [Step::COLUMNS => ['name', 'email']]
    )
    ->load($loader, 'users')
    ->run();

The library is fully compatible with any PHP project. For instance, with Symfony, you can fully benefit from the autowiring. On the following example, you enable it on the main ETL object, with the shared parameter to false in order to have the possibility to get different instance of the ETL (optionnal).

services.yaml

    Wizaplace\Etl\Etl:
        shared: false
