Pheasant

Pheasant is an object relational mapper written to take advantage of PHP 5.3. Simple relationships are supported, with the emphasis being on scalability and performance over complexity.

Pheasant doesn't attempt to abstract the database and makes heavy use of MySQL/Innodb features.

Status of Development

Running in production on 99designs.com. See ROADMAP for more details on future plans.

Installing

Easiest way is to install via composer http://packagist.org/packages/lox/pheasant.

Persisting Objects

Each domain object has a set of properties and relationships that are defined in the configure method. Each domain object delegates to a mapper object for the actual saving and loading of objects.

<?php

use \Pheasant;
use \Pheasant\Types;

class Post extends DomainObject
{
	public function properties()
	{
		return array(
			'postid'   => new Types\Sequence(),
			'title'    => new Types\String(255, 'required'),
			'subtitle' => new Types\String(255),
			'status'   => new Types\Enum(array('closed','open')),
			'authorid' => new Types\Integer(11),
			);
	}

	public function relationships()
	{
		return array(
			'Author' => Author::hasOne('authorid')
			);
	}
}

class Author extends DomainObject
{
	public function properties()
	{
		return array(
			'authorid' => new Types\Sequence(),
			'fullname' => new Types\String(255, 'required')
			);
	}

	public function relationships()
	{
		return array(
			'Posts' => Post::hasOne('authorid')
			);
	}
}

// configure database connection
Pheasant::setup('mysql://localhost:/mydatabase');

// create some objects
$author = new Author(array('fullname'=>'Lachlan'));
$post = new Post(array('title'=>'My Post', 'author'=>$author));

// save objects
$author->save();
$post->save();

echo $post->title; // returns 'My Post'
echo $post->Author->fullname; // returns 'Lachlan'

Magical Finders

Many variations of finders are available for locating objects:

<?php

// all users
$users = User::all();

// all users named frank
$users = User::find('firstname = ?', 'frank');

// any fields can be used in finders, this translates to above
$users = User::findByFirstName('frank');

// a single user named frank
$users = User::one('firstname = ?', 'frank');

// the most recent user
$user = User::last();

// the most recent user named either frank or bob
$user = User::findByFirstName(array('Frank','Bob')->last();

Events

Code can be triggered before and after create, update and delete operations.

<?php

use \Pheasant;
use \Pheasant\Events;
use \Pheasant\Types;

class Post extends DomainObject
{
  public function properties()
  {
    return array(
      'postid'      => new Types\Sequence(),
      'title'       => new Types\String(255),
      'timecreated' => new Types\Integer(11),
      ));
  }

  public function beforeCreate($post)
  {
    $d->timecreated = time();
  }
}

Optionally, domain objects provide the following implicit hooks which can be overriden:

afterCreate
beforeUpdate, afterUpdate
