The Power ORM


CRUD stands for Create, Update, Retrieve and Delete. CRUD operations are the core of many web applications.

Working with beans

RedBeanPHP works with beans. Most interactions with the database are accomplished using beans. Beans are used to carry data from and to the database.

Every bean has a type and an ID. The type of a bean tells you which table in the database is used to store the bean. Every type maps to a corresponding table. The ID of a bean is the primary key of the corresponding record.
You can create a new bean by dispensing one.


To create a new bean (of type 'book') use:

    $book R::dispense'book' );

You can now add properties:

    $book->title 'Learn to Program';
$book->rating 10;

You can also use array notation if you like:

    $book['price'] = 29.99//you can use array notation as well

and store the bean in the database:

    $id R::store$book );

At this point, the bean will be stored in the database and all tables and columns have been created.
The bean will now have an ID, which is also returned for your convenience.

RedBeanPHP will build all the necessary structures to store your data. However custom indexes and constraints have to be added manually (after freezing your web application).


You can dispense any type of bean you like, as long as the type name consists of lowercase alphabetical characters:

    $page R::dispense('page'); //valid

$page R::dispense'Page' ); //invalid: uppercase
$page R::dispense'cms_page' ); //invalid: _
$page R::dispense'@#!' ); //invalid

However dispense also offers some shortcuts:

    $twoBooks R::dispense'book');

$book$page) = R::dispenseAll'book,page' );
$book$pages) = R::dispenseAll'book,page*2' );

Properties of beans may contain alphanumeric characters and underscores. Camelcased properties will automatically convert to snake_case:

    $book->isSoldOut TRUE//is_sold_out
$book->hasISBNCode TRUE//has_isbn_code


To load a bean, simply pass the type and ID of the bean you're looking for:

    $book R::load'book'$id ); //reloads our book

If the bean does not exist an empty bean with ID 0 will be returned.


To update a bean in the database, add or change properties:

    $book->title 'Learn to fly';
$book->rating 'good';
$book->published '2015-02-15';
R::store$book );

Note that we added a new property 'published', RedBeanPHP will add a new column of type 'date' for this property. Also, it will widen the 'rating' from INTEGER to VARCHAR to support text as well as numbers.

    //Examples of other data types
$meeting->when '19:00:00'//Time
$meeting->when '1995-12-05'//Date
$photo->created '1995-12-05 19:00:00'//Date time
$meeting->place '(1,2)'//SPATIAL only works in postgreSQL
$price->amount '12.37'//FIXED POINT NUMERIC - MySQL and Postgres
$price->amount '$25.00'//MONEY TYPE - Postgres only

If you want a suitable data type of monetary values, use the 'XX.XX' format and you'll get a fixed precision number data field. To make use of Postgres special purpose, currency-aware money data type, prefix the value with a common currency symbol.

You can use R::isoDate() and R::isoDateTime() to generate the current date(time) if you like.

As of RedBeanPHP 4.1 you can also use spatial columns for MySQL, learn more.

RedBeanPHP will dynamically add new columns to your database. It determines the column type to use by looking at the value you are trying to store. For instance, a short text might be stored as a VARCHAR while a large text might be stored as TEXT. Similarly, a boolean value will probably get stored as TINYINT but when you put a float in that property the column will probably be changed to FLOAT or DOUBLE (depending on your database).
Some column types behave differently, for instance if you store a valid ISO formatted date (i.e. 2015-01-01) RedBeanPHP builds a DATE column, but this column will not change. In general, RedBeanPHP tries to adapt the database to your application. If you're done developing, you can freeze the database using the freeze() function. After that, the database schema will no longer change (because it is very unlikely you want to store something other than a date in a column you filled with perfectly formatted date in the first place).
Note that RedBeanPHP will never throw away columns or 'shrink' columns (from TEXT to VARCHAR) to avoid data loss. RedBeanPHP also only manipulates column types it recognizes, so if you change a VARCHAR(255) to a VARCHAR(254) it will leave that column alone, since it no longer recognizes the type. This means that if you customize columns, RedBeanPHP leaves them alone from that point on.
If RedBeanPHP alters the database in a way you don't like, don't worry, you can always tune the schema to your liking (just use your database management tool or phpmyadmin), you can even freeze certain tables only.


To delete a bean:

    R::trash$book ); //for one bean
R::trashAll$books ); //for multiple beans

To delete all beans of a certain type:

    R::wipe'book' ); //burns all the books!

To destroy the entire database simply invoke the nuclear method (be careful!):



To load a series of beans use:

    $books R::loadAll'book'$ids );


To quickly reload a bean:

    $bean $bean->fresh();

Finding Beans

Instead of loading beans, you can also use the find() method to search for beans using certain criteria. Learn how to query beans in RedBeanPHP.
