db-controller

Php PDO wrapper

Installation

Installation is super-easy via Composer:

composer require peterujah/db-controller

USAGES

Initialize DBController with configuration array

$handler = new \Peterujah\NanoBlock\DBController($configArray);

Or extend \Peterujah\NanoBlock\DBController to set your connection details like below

class Conn extends \Peterujah\NanoBlock\DBController{ 
	public function __construct(bool $development = false){
		$config = array(
			"PORT" => 3306,
			"HOST" => "localhost",
			"VERSION" => "mysql",
		);
		if($development){
			$config["USERNAME"] = "root";
			$config["PASSWORD"] = "";
			$config["NAME"] = "dbname";
		}else{
			$config["USERNAME"] = "dbusername";
			$config["PASSWORD"] = "dbpass";
			$config["NAME"] = "dbname";
		} 
		$this->onDebug = $development;
		$this->config = $config;
		$this->onCreate();
	}
}

Initialize your custom class

$handler = new Conn($_SERVER["HOST_NAME"]=="localhost");

Now run query select, insert, update, delete etc.. using prepare statment

$handler->prepare('SELECT * FROM users WHERE username = :username LIMIT 1');
$handler->bind(':username', "Peter");
$handler->execute();
$res = $handler->getOne();
$handler->free();

Or run query select, insert, update, delete etc.. using query

$handler->query('SELECT * FROM users');
$res = $handler->getAll();
$handler->free();
