JSON Paths that need Double Quotes

See more JSON Examples

This example explains and demonstrates the situations where parts within a JSON path need to be enclosed in double-quotes. Chilkat2 PHP

<?php

use Chilkat2\JsonObject;

// Imagine we have the following JSON:

//     {
//       "Meta Data": {
//         "1: Symbol": "MSFT",
//         "2: Indicator": "Relative Strength Index (RSI)",
//         "3: Last Refreshed": "2017-07-28 09:30:00",
//         "4: Interval": "15min",
//         "5: Time Period": 10,
//         "6: Series Type": "close",
//         "7: Time Zone": "US/Eastern Time"
//       },
//       "Technical Analysis: RSI": {
//         "2017-07-28 09:30": {
//           "RSI": "38.6964"
//         },
//         "2017-07-27 16:00": {
//           "RSI": "50.0088"
//         }
//     }

// The path to the RSI valud 38.6964 is Technical Analysis: RSI.2017-07-28 09:30.RSI

// Whenever a path part contains a SPACE or "." char, that part must be enclosed
// in double quotes.  For example:

$json = new JsonObject();
$json->LoadFile('qa_data/json/rsi.json');

echo 'RSI: ', $json->StringOf('"Technical Analysis: RSI"."2017-07-28 09:30".RSI'), "\n";

// output is 38.6964
