-array
-^^^^^
-
-Maps and converts array data based on PHP serialization.
-If you need to store an exact representation of your array data,
-you should consider using this type as it uses serialization
-to represent an exact copy of your array as string in the database.
-Values retrieved from the database are always converted to PHP's ``array`` type
-using deserialization or ``null`` if no data is present.
-
-.. note::
-
-    This type will always be mapped to the database vendor's ``text`` type
-    internally as there is no way of storing a PHP array representation
-    natively in the database.
-    Furthermore this type requires an SQL column comment hint so that it can be
-    reverse engineered from the database. Doctrine cannot map back this type
-    properly on vendors not supporting column comments and will fall back to
-    ``text`` type instead.
-
-.. warning::
-
-    This type is deprecated since 3.4.0, use :ref:`json` instead.

-    While the built-in ``text`` type of MySQL and MariaDB can store binary data,
-    ``mysqldump`` cannot properly export ``text`` fields containing binary data.

-.. warning::
-
-    Because the built-in ``text`` type of PostgreSQL does not support NULL bytes,
-    the object type will cause deserialization errors on PostgreSQL. A workaround is
