Using JSON StringOf with Non-String Members

See more JSON Examples

If a JSON member is a boolean, integer, or null, using StringOf will return its string representation. Chilkat2 PHP

<?php

use Chilkat2\JsonObject;

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

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

$json->EmitCompact = false;
echo $json->Emit(), "\n";

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

$a = $json->StringOf('a');
echo $a, "\n";

$b = $json->StringOf('b');
echo $b, "\n";

$c = $json->StringOf('c');
echo $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');
$bval = $json->BoolOf('b');
$hasNull = $json->IsNullOf('c');
