Doctrine Array Hydration with db column names keys

Question

Using the latest Doctrine (2.4) Given this simple entity:

class Booking
{
    /**
     * @var integer
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * @var \DateTime
     * @ORM\Column(name="from_date", type="datetime", nullable=true)
     */
    protected $fromDate;

    /**
     * @var float
     * @ORM\Column(name="deposit_price", type="float", nullable=true)
     */
    protected $depositPrice;
}

If I do a simple ORM query with array Hydration the result I get back is something like this:

[
   'id'=>1,
   'depositPrice'=>100.5,
   'fromDate'=>'2012-01-01'
]

Is there a simple way to Hydrate using the actual column fields? To get a result like this:

[
    'id'=>1,
    'deposit_price'=>100.5,
    'from_date'=>'2012-01-01'
]

There are 3 solutions:

• You can create custom hydration and do in it what you want.
• You can use Native query and Result Set Mapping .
• You can just rename your fields in your Entity class.

I would prefer 3rd case. It is so easy to rename your fields. You can do it on all files with regular expressions (if it is supported by your IDE).
