Example

The following code shows a very simple usage example.

//load the class "Json"
require_once 'Json.php';
use webfiori\json\Json;

//initialize an object of the class Json
$j = new Json();

//add a number attribute
$j->addNumber('my-number', 34);

//add a boolean with 'false' as its value. 
$j->addBoolean('my-boolean', false);

//add a string
$j->addString('a-string', 'Hello, I\'m Json! I like "JSON". ');

header('content-type:application/json');
/*
send back the generated json string.
The output of the code will be like that:
{
    "my-number":34,
    "my-boolean":false,
    "my-number":"Hello, I'm Json! I like \"json\". ",
}
*/
echo $j;

Following example shows how data can be added directly using the constructure.

$jsonObj = new Json([
    'first-name' => 'Ibrahim',
    'last-name' => 'BinAlshikh',
    'age' => 26,
    'is-married' => true,
    'mobile-number' => null
]);

The JSON output of this code will be the following:

{
    "first-name":"Ibrahim",
    "last-name":"BinAlshikh",
    "age":26,
    "is-married":true,
    "mobile-number":null
}
