Installing via Composer

The recommended way to install MySQL Keeper is though Composer.

{
    "require": {
        "zortje/mysql-keeper": "~0.0"
    }
}

Usage

$pdo = new PDO('mysql:host=127.0.0.1;dbname=myapp', 'root', '');

$database = DatabaseFactory::create($pdo);
$databaseResult = $database->getResult();

The $databaseResult array will look something like this with the first level keys being table names.

[
	'users' => [
		'issues' => [
			[
				'type' => 'field',
				'field' => 'id',
				'description' => 'Set as auto_increment but has no primary key'
			],
			[
				'type' => 'field',
				'field' => 'id',
				'description' => 'Set as auto_increment but is not set as primary'
			]
		],
		'optimizations' => [
			[
				'type' => 'field',
				'field' => 'id',
				'description' => 'Field should be unsigned, as no field values are negative'
			]
		]
	]
];
