README

Pimple Service Provider for creating PDO handlers.

Installation with Composer

$ composer require germania-kg/databases

Setup

<?php
use Germania\Databases\DatabasesServiceProvider;

// A. Use with Slim or Pimple
$app = new \Slim\App;
$dic = $app->getContainer();
$dic = new Pimple\Container;

// B. Register Service Provider.
// see https://pimple.symfony.com/#extending-a-container
// Optionally pass custom PDO error mode
$dic->register( new DatabasesServiceProvider );
$dic->register( new DatabasesServiceProvider( \PDO::ERRMODE_EXCEPTION ) );

Services

PDO.Factory

Factory callable for PDO handlers. Just have some database credentials at hand.

<?php
$db = [
	'dsn' => "mysql:host=localhost;dbname=MyDatabase;charset=utf8",
	'user' => "username",
	'pass' => "secret"
];

// Grab Factory
$pdo_factory = $dic['PDO.Factory'];

// Create handler
$pdo = $pdo_factory( $db );
$pdo = $pdo_factory( (object) $db ); // StdClass objects
$pdo = $pdo_factory( new \ArrayObject($db) ); // ArrayAccess instance

Exceptions

The factory accepts an array, ArrayAccess instance or a StdClass object. If the factory parameter passed does not match any of these, an \InvalidArgumentException will be thrown

PDO.ErrorMode

The default error mode has been set on Service provider instantiation. You may override it at runtime by extending the service definition:

$dic->extend(PDO.ErrorMode', function($default_error_mode, $dic) {
    return \PDO::ERRMODE_SILENT;
});

PDO.Options

This service returns the PDO options to use on PDO handler instantiation. By default this is an array with the PDO.ErrorMode shown above.

$pdo_options = $dic['PDO.Options'];

Overriding

Just extend the service definition. See PHP manual: class PDO for valid options.

$dic->extend('PDO.Options', function($default_options, $dic) {
    return array_merge( $default_options, array(
    	\PDO::ATTR_ERRMODE => \PDO::ERRMODE_SILENT
    	// custom values here
    ));
});

Development

$ git clone https://github.com/GermaniaKG/Databases.git
$ cd Databases
$ composer install

Unit tests

Either copy phpunit.xml.dist to phpunit.xml and adapt to your needs, or leave as is. Run PhpUnit test or composer scripts like this:

$ composer test
# or
$ vendor/bin/phpunit
