README

A powerful database wrapper library built on top of Medoo, providing a simple and intuitive interface for database operations in PHP applications.

Installation

composer require websitesql/database

Basic Usage

Initialization

// Initialize the database provider
$db = new WebsiteSQL\Database\Database([
    'type' => 'mysql',
    'host' => 'localhost',
    'database' => 'name',
    'username' => 'your_username',
    'password' => 'your_password'
], '../migrations');

CRUD Operations

Select Data

// Select all records from users table
$users = $db->select("users", "*");

// Select with conditions
$user = $db->get("users", "*", ["id" => 1]);

// Select with JOIN
$data = $db->select("posts", [
    "[>]users" => ["user_id" => "id"]
], [
    "posts.id",
    "posts.title",
    "users.username"
], [
    "posts.status" => "published",
    "ORDER" => ["posts.created" => "DESC"]
]);

Insert Data

$db->insert("users", [
    "username" => "john_doe",
    "email" => "john@example.com",
    "created" => date("Y-m-d H:i:s")
]);

// Get last inserted ID
$lastId = $db->id();

Update Data

$db->update("users", [
    "email" => "new_email@example.com"
], [
    "id" => 1
]);

Delete Data

$db->delete("users", [
    "id" => 1
]);

Migrations

The database library includes a migration system for managing database schema changes:

// Run migrations
$db->migrations()->up();

// Rollback the last batch of migrations
$db->migrations()->down();

// Rollback all migrations
$db->migrations()->reset();

// Refresh migrations (rollback all and run again)
$db->migrations()->refresh();
