Good PHP ORM Library?

Answer 1

Have a look at the LEAP ORM for Kohana. It works with a bunch of databases, including DB2, Drizzle, Firebird, MariaDB, SQL Server, MySQL, Oracle, PostgreSQL, and SQLite. With a simple autoload function, it can work with almost any PHP framework. The source code is on GitHub at https://github.com/spadefoot/kohana-orm-leap. You can checkout LEAP's tutorials online.

The ORM library works with non-integer primary keys and composite keys. Connections are managed via a database connection pool and it works with raw SQL queries. The ORM even has a query builder that makes building SQL statements super simple.

Agile Toolkit has its own unique implementation of ORM/ActiveRecord and dynamic SQL.

Introduction: http://agiletoolkit.org/intro/1

Syntax (Active Record):

$emp=$this->add('Model_Employee');
$emp['name']='John';
$emp['salary']=500;
$emp->save();

Syntax (Dynamic SQL):

$result = $emp->count()->where('salary','>',400)->getOne();

While Dynamic SQL and Active Record/ORM is usable directly, Agile Toolkit further integrates them with User Interface and jQuery UI. This is similar to JSF but written in pure PHP.

$this->add('CRUD')->setModel('Employee');

This will display AJAXified CRUD with for Employee model.

Answer 3

If you are looking for an ORM that implements the Data Mapper paradigm rather than Active Record specifically, then I would strongly suggest that you take a look at GacelaPHP.

Gacela features:

• Data mapper
• Foreign key mapping
• Association mapping
• Dependent mapping
• Concrete table inheritance
• Query object
• Metadata mapping
• Lazy & eager loading
• Full Memcached support

Other ORM solutions are too bloated or have burdensome limitations when developing anything remotely complicated. Gacela resolves the limitations of the active record approach by implementing the Data Mapper Pattern while keeping bloat to a minimum by using PDO for all interactions with the database and Memcached.

Check out Outlet ORM. It is simpler than Propel and Doctrine and it works similar to Hibernate, only with more of a PHP feel to it.
