Chilkat2 PHP

<?php

use Chilkat2\JsonArray;
use Chilkat2\JsonObject;

// This example requires Chilkat v9.5.0.64 or greater.

// Loading into a new JSON array is simple and straightforward.
$a = new JsonArray();
$a->Load('[ 1,2,3,4 ]');

// Output:  [1,2,3,4]
echo $a->Emit(), "\n";
echo "--------\n";

// The JsonArray's Load and LoadSb methods have a peculiar behavior when
// it is already part of a JSON document.  In this case, the JsonArray
// becomes detached, and the original document remains unchanged.
// This is intentional due to the nature of the internal implementation.
// For example:

$json = new JsonObject();
$json->Load('{ "abc": [ 1,2,3,4 ] }');

// Output:  (json) {"abc":[1,2,3,4]}
echo '(json) ', $json->Emit(), "\n";
echo "--------\n";

$abc = $json->ArrayOf('abc');
// When Load is called, abc becomes it's own document, and the original is not modified.
$abc->Load('[ 5,6,7,8 ]');

// Output: (abc) [5,6,7,8]
echo '(abc) ', $abc->Emit(), "\n";
echo "--------\n";

// Output: (json) {"abc":[1,2,3,4]}
echo '(json) ', $json->Emit(), "\n";
echo "--------\n";
