Doctrine comes with a large number of field types available. Each of these

maps a PHP data type to a specific column type in whatever database you're

using. The following types are supported in Doctrine:

* **Strings**

* ``string`` (used for shorter strings)

* ``text`` (used for larger strings)

* **Numbers**

* ``integer``

* ``smallint``

* ``bigint``

* ``decimal``

* ``float``

* **Dates and Times** (use a `DateTime`_ object for these fields in PHP)

* ``date``

* ``time``

* ``datetime``

* ``datetimetz``

* **Other Types**

* ``boolean``

* ``object`` (serialized and stored in a ``CLOB`` field)

* ``array`` (serialized and stored in a ``CLOB`` field)

* ``blob`` (mapped to a resource stream)

* ``simple_array`` (serialized using:phpfunction:`implode()` and:phpfunction:`explode()`,

with a comma as delimiter, and stored in a ``CLOB`` field)

* ``json_array`` (serialized using:phpfunction:`json_encode()` and:phpfunction:`json_decode()`,

and stored in a ``CLOB`` field)

* ``guid``

For more information, see Doctrine's `Mapping Types documentation`_.

Field Options

Each field can have a set of options applied to it. The available options

include ``type`` (defaults to ``string``), ``name``, ``length``, ``unique``

and ``nullable``. Take a few examples:

..code-block::yaml

..code-block::xml
