// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:

$json = new CkJsonObject();

$success = $json->Load($jsonStr);
if ($success != true) {
    print $json->lastErrorText() . "\n";
    exit;
}

// To pretty-print, set the EmitCompact property equal to false
$json->put_EmitCompact(false);

// If bare-LF line endings are desired, turn off EmitCrLf
// Otherwise CRLF line endings are emitted.
$json->put_EmitCrLf(false);

// Emit the formatted JSON:
print $json->emit() . "\n";
