Create a builder

To build some JSON, you will need to instantiate a builder:

1

3

use FOS\CKEditorBundle\Builder\JsonBuilder;

$builder = new JsonBuilder();

Set your values

To set your values on the builder, you can either use setValues or setValue but be aware they don't behave same. Basically, setValues allows you to append a set of values in the builder without escaping control whereas setValue allows you to append one value in the builder but with escaping control.

Append a set of values

To append a set of values in the builder, just use setValues and pass your values as first argument:

1

$builder->setValues(array('foo' => array('bar')));

Additionally, this method takes as second argument a path prefix (PropertyAccess Component) which allows you to append your values where you want in the builder graph. So, the next sample is basically the equivalent of the precedent:

1

$builder->setValues(array('bar'), '[foo]');

Append one value

To append one value in the builder, just use setValue and pass the path as first argument and the value as second one:

1

$builder->setValue('[foo][0]','bar');

If you want to keep control of the value escaping, this part is for you. Basically, just pass false as third argument:

1

$builder->setValue('[foo][0]','bar', false);

Configure the JSON encode options

By default, the JSON builder uses the native json_encode options. To override it, you can use:

1
2

$builder->setJsonEncodeOptions(JSON_FORCE_OBJECT);
$jsonEncodeOptions = $builder->getJsonEncodeOptions();

Values for those options can be found in PHP documentation for json_decode()

Build your JSON

Once your builder is well configured, you can build your JSON:

1

$json = $builder->build();

// {"0":"foo","1":bar}
echo $builder
    ->setJsonEncodeOptions(JSON_FORCE_OBJECT)
    ->setValues(array('foo'))
    ->setValue('[1]', 'bar', false)
    ->build();

// {"foo":["bar"],"baz":bat}
echo $builder
    ->reset()
    ->setValues(array('foo' => array('bar')))
    ->setValue('[baz]', 'bat', false)
    ->build();
