Convert json encoded String to json object in FosRestBundle

Question

I have a json encoded string in one of my DB fields, e.g.

[{"name":"car","price":"10"}]

I'm using the FosRestBundle to return the DB-Values in json format and the String above is returned - as String - nothing special until here;)

How can this String be converted, so that a Json Object is returned instead?

Finally I found the solution.

My Entity contained this:

/**
 * @var string
 *
 * @ORM\Column(name="options", type="string", nullable=true)
 */
private $options;

"options" contained the json encoded string. So I tried it with the JMS Serilizer Annotation @Accessor and wrote this specific getter:

/**
 * Get optionsAsArray
 *
 * @return array
 */
public function getOptionsAsArray()
{
    return (array)json_decode($this->options, true);
}

Still got an error "Array to string conversion". So the Solution was, to add another Annotation @type and the JMSSerializer returned nicely formatted JSON.

This is what the Entity has to look like:

use JMS\Serializer\Annotation\Accessor;
use JMS\Serializer\Annotation\Type;


/* ... */

/**
 * @var string
 *
 * @ORM\Column(name="options", type="string", nullable=true)
 * @Accessor(getter="getOptionsAsArray")
 * @Type("array")
 */
private $options;
