Database Component is a database toolkit for PHP. At the moment, it uses the Laravel database library as its sole engine.

Installation

composer require pollen-solutions/database

Basic Usage

Add the default connexion

use Pollen\Database\DatabaseManager;

$db = new DatabaseManager();

$db->addConnection([
    'driver'    => 'mysql',
    'host'      => 'localhost',
    'database'  => 'pollen-solutions',
    'username'  => 'root',
    'password'  => 'root',
    'charset'   => 'utf8mb4',
    'collation' => 'utf8mb4_general_ci',
    'prefix'    => 'xyz_',
]);

Using The Schema Builder

use Illuminate\Database\Schema\Blueprint;
use Pollen\Database\DatabaseManagerInterface;

/** @var DatabaseManagerInterface $db */
$schema = $db->getConnection()->getSchemaBuilder();
$schema->create('posts', function (Blueprint $table) {
    $table->increments('id');
    $table->string('title');
    $table->longText('content')->nullable();
    $table->timestamps();
});

More usage informations on Laravel online official documentation

Using The Query Builder

use Pollen\Database\DatabaseManagerInterface;

/** @var DatabaseManagerInterface $db */
$posts = $db->getConnection()->table('posts')->get();

var_dump($posts);
exit;

Optional configuration

Static methods call

use Pollen\Database\DatabaseManagerInterface;
use Pollen\Database\DatabaseManager as DB;

/** @var DatabaseManagerInterface $db */
$db->setAsGlobal();

// Now you can call DatabaseManager methods as static.
$posts = DB::table('posts')->get();

var_dump($posts);
exit;

Eloquent model

Prerequisite

use Pollen\Database\DatabaseManagerInterface;

/** @var DatabaseManagerInterface $db */
$db->bootEloquent();

Configuration with .env

Coupled with an implementation of .env , Pollen Database could automatically add the default connection.

# In a /var/www/html/.env file
DATABASE_URL=sqlite:///var/www/html/var/database.sqlite

<?php

use Pollen\Database\DatabaseManager;
use Pollen\Support\Env;

Env::load('/var/www/html');

$db = (new DatabaseManager())->withDefaultEnvConnection();

try {
    $db->getConnection();
} catch (InvalidArgumentException $e) {
    trigger_error($e->getMessage());
}
exit;
