// Create JSON with members of different data types.
$json = new COM("Chilkat.JsonObject");

$json->UpdateInt('a',123);
$json->UpdateBool('b',1);
$json->UpdateNull('c');

$json->EmitCompact = 0;
print $json->emit() . "\n";

// Resulting JSON:
// {
//   "a": 123,
//   "b": true,
//   "c": null

print $a . "\n";

$b = $json->stringOf('b');
print $b . "\n";

$c = $json->stringOf('c');
print $c . "\n";

// Output

// 123
// true
// null

// If you want to get the integer, boolean, or null value
// you need to use the methods matching the data type
$ival = $json->IntOf('a');
