PDO mysql Connection for Slim 3 framework.

Installation

Configuration

Create an array of session settings in you application settings.

$settings = [
    'settings' => [
        'listdb' => [
            'db1' => [
                'dsn'  => 'mysql:host=localhost;dbname=nama_name;charset=utf8',
                'user' => 'root',
                'pass' => 'yourpassword'
            ],
            'db2' => [
                'dsn'  => 'mysql:host=localhost;dbname=nama_name;charset=utf8',
                'user' => 'root',
                'pass' => 'yourpassword'
            ]
        ]
    ]
];

Usage

You can inject session helper class in application container:

$c['dbConn'] = function($c){  
    return new \nanaksr\dbconn($c->get('settings')['listdb']);
};

if dbcon class is injected in application container and can be used as an object, i.e. like this:

$app->get('/', function (Request $request, Response $response) {
    // Namespace is now picked up from settings
    $db1 = $this->dbconn->pdo('db1');
    $data = $db1->prepare("SELECT * FROM `mytable`");
    $data->execute();
   return print_r($data->fetchAll());
});

with container resolution:

class Home
{
    protected $ci;
    public function __construct($ci)
    { 
        $dbConn      = $ci->get('dbConn');
        $this->db1   = $dbConn->pdo('db1');
    }
    
    public function __invoke(Request $request, Response $response, $args)
    {
        $data = $this->db1->prepare("SELECT * FROM `mytable`");
        $data->execute();
        return print_r($data->fetchAll());
    }
}
