Helpers
Json
When creating views that return JSON, it's important to also set the appropriate response header. The JSON view helper does exactly that. In addition, by default, it disables layouts (if currently enabled), as layouts generally aren't used with JSON responses.
The JSON helper sets the following header:
Content-Type: application/json
Most XmlHttpRequest libraries look for this header when parsing responses to determine how to handle the content.
Basic Usage
<?= $this->json($this->data) ?>
Deprecated
Enabling encoding using Laminas\Json\Expr
This feature of the Json view helper has been deprecated in version 2.16 and will be removed in version 3.0.
The JSON helper accepts an array of options that will be passed to Laminas\Json\Json::encode()
and
used internally to encode data.
Laminas\Json\Json::encode
allows the encoding of native JSON expressions using Laminas\Json\Expr
objects. This option is disabled by default. To enable this option, pass a boolean true
to the
enableJsonExprFinder
key of the options array:
<?= $this->json($this->data, ['enableJsonExprFinder' => true]) ?>

The JSON helper accepts an array of options that will be passed to `Laminas\Json\Json::encode()` and
used internally to encode data.
`Laminas\Json\Json::encode` allows the encoding of native JSON expressions using `Laminas\Json\Expr`
objects. This option is disabled by default. To enable this option, pass a boolean `true` to the
`enableJsonExprFinder` key of the options array:
```php
<?= $this->json($this->data, ['enableJsonExprFinder' => true]) ?>
