README

This is a simple PDO based mysql Query Builder

Installation

composer require mrmadclown/mnemosyne

Usage

The Builder gets constructed by passing an instance of the PDO::class to the \MrMadClown\Mnemosyne\Builder::class

use \PDO;

$pdo = new \PDO();
$builder = new \MrMadClown\Mnemosyne\Builder($pdo);

With the Builder Object a mysql query can be build similar to how a query would be written:

...

$builder->select('*')->from('users')->where('id', 1);

Important

By default, the PDO Fetch Mode is set to PDO::FETCH_CLASS | PDO::FETCH_PROPS_LATE; which means you have to have a class which represents your table

#User.php
class User {
    public int $id;
    public string $name;
}

$builder->setClassName(User::class)->fetchAll(); // returns an array of Users

you can use the magic __set method to map your database columns into your model. If you don`t want a different FetchMode you can call $builder->setFetchMode(\PDO::FETCH_ASSOC) to change the fetch mode of the Builder instance.
