Idiorm

[![Build Status](https://travis-ci.org/j4mie/idiorm.png?branch=master)](https://travis-ci.org/j4mie/idiorm) [![Latest Stable Version](https://poser.pugx.org/j4mie/idiorm/v/stable.png)](https://packagist.org/packages/j4mie/idiorm) [![Total Downloads](https://poser.pugx.org/j4mie/idiorm/downloads.png)](https://packagist.org/packages/j4mie/idiorm) [![Code Climate](https://codeclimate.com/github/j4mie/idiorm/badges/gpa.svg)](https://codeclimate.com/github/j4mie/idiorm)

### Feature/API complete

Idiorm is now considered to be feature complete as of version 1.5.0. Whilst it will continue to be maintained with bug fixes there will be no further new features added from this point on. This means that if a pull request makes breaking changes to the API or requires anything other than a patch version bump of the library then it will not be merged.

**Please do not submit feature requests or API breaking changes as they will be closed without ceremony.**

---

A lightweight nearly-zero-configuration object-relational mapper and fluent query builder for PHP5 and above.

Tested on PHP 5.2.0+ - may work on earlier versions with PDO and the correct database drivers.

Released under a [BSD license](http://en.wikipedia.org/wiki/BSD_licenses).

**See Also: [Paris](http://github.com/j4mie/paris), an Active Record implementation built on top of Idiorm.**

Features
--------

* Makes simple queries and simple CRUD operations completely painless.
* Gets out of the way when more complex SQL is required.
* Built on top of [PDO](http://php.net/pdo).
* Uses [prepared statements](http://uk.php.net/manual/en/pdo.prepared-statements.php) throughout to protect against [SQL injection](http://en.wikipedia.org/wiki/SQL_injection) attacks.
* Requires no model classes, no XML configuration and no code generation: works out of the box, given only a connection string.
* Consists of one main class called `ORM`. Additional classes are prefixed with `Idiorm`. Minimal global namespace pollution.
* Database agnostic. Currently supports SQLite, MySQL, Firebird and PostgreSQL. May support others, please give it a try!
* Supports collections of models with method chaining to filter or apply actions to multiple results at once.
* Multiple connections supported
* PSR-1 compliant methods (any method can be called in camelCase instead of underscores eg. `find_many()` becomes `findMany()`) - you'll need PHP 5.3+

Documentation
-------------

The documentation is hosted on Read the Docs: [idiorm.rtfd.org](http://idiorm.rtfd.org)

### Building the Docs ###

You will need to install [Sphinx](http://sphinx-doc.org/) and then in the docs folder run:

    make html

The documentation will now be in docs/_build/html/index.html

Let's See Some Code
-------------------

```php
$user = ORM::for_table('user')
    ->where_equal('username', 'j4mie')
    ->find_one();

$user->first_name = 'Jamie';
$user->save();

$tweets = ORM::for_table('tweet')
    ->select('tweet.*')
    ->join('user', array(
        'user.id', '=', 'tweet.user_id'
    ))
    ->where_equal('user.username', 'j4mie')
    ->find_many();

foreach ($tweets as $tweet) {
    echo $tweet->text;
}
```

Tests
-----

Tests are written with PHPUnit and be run through composer

    composer test

To make testing on PHP 5.2 (Idiorm maintains support back to this version of PHP) there
is a Docker setup in `./test/docker_for_php52` - check the readme in there for more.

* Back out pull request/issue [#133](https://github.com/j4mie/idiorm/pull/133) as it breaks backwards compatibility in previously unexpected ways (see [#162](https://github.com/j4mie/idiorm/pull/162), [#156](https://github.com/j4mie/idiorm/issues/156) and [#133](https://github.com/j4mie/idiorm/pull/133#issuecomment-29063108)) - sorry for merging this change into Idiorm - closes [issue 156](https://github.com/j4mie/idiorm/issues/156)
