= 5.3 Description: This BMI calculator service shows how you can serve data in different formats using Restler. This example uses JsonFormat (default) and XmlFormat. First format specified in `Restler::setSupportedFormats` is used as the default format when client does not specify the format. Client can specify the format either using extension like .json or specify the MIME type in HTTP Accept Header. When we make the request from the browser we will get xml when we skip the extension because XML is one of the requested formats specified in the HTTP Accept Header where as a AJAX request or CURL will return JSON. Example 1: GET bmi returns 31.77 Obesity 162.6 centimeter 84 kilograms 5 feet 4 inches 185.19 pounds Example 2: GET bmi.xml returns 31.77 Obesity 162.6 centimeter 84 kilograms 5 feet 4 inches 185.19 pounds Example 3: GET bmi.json returns { "bmi": 31.77, "message": "Obesity", "metric": { "height": "162.6 centimeter", "weight": "84 kilograms" }, "imperial": { "height": "5 feet 4 inches", "weight": "185.19 pounds" } } */ require_once '../../../vendor/restler.php'; use Luracast\Restler\Restler; $r = new Restler(); $r->setSupportedFormats('JsonFormat', 'XmlFormat'); $r->addAPIClass('BMI'); $r->handle();
