Answer 1

In addition to @kuldeep.kamboj, I should say CJSON::encode will treat that 17 as an integer if you define the data type of the value like this:

// PHP
$toBeConverted = array('id' => (int) 17); // or (int) $myInteger

$jsonString = \CJSON::encode($toBeConverted);    

// $jsonString will be:
{
    "id": 17
}
