(PHP Extension) Firebase PATCH - Updating Data

Uses the PATCH method to update record with new information. The data used in this example is at Chilkat Firebase Pigs Database, and is shown here:

Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux, Solaris

<?php

// 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:
include("chilkat_9_5_0.php");

// Uses the PATCH method to update a Firebase record.

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// This example assumes a JWT authentication token, if required, has been previously obtained.
// See Get Firebase Access Token from JSON Service Account Private Key for sample code.

// Load the previously obtained Firebase access token into a string.
$fac = new CkFileAccess();
$accessToken = $fac->readEntireTextFile('qa_data/tokens/firebaseToken.txt','utf-8');
if ($fac->get_LastMethodSuccess() != true) {
    print $fac->lastErrorText() . "\n";
    exit;
}

$rest = new CkRest();

// Make the initial connection (without sending a request yet).
// Once connected, any number of requests may be sent.  It is not necessary to explicitly
// call Connect before each request.  
$success = $rest->Connect('chilkat.firebaseio.com',443,true,true);
if ($success != true) {
    print $rest->lastErrorText() . "\n";
    exit;
}

$authGoogle = new CkAuthGoogle();
$authGoogle->put_AccessToken($accessToken);
$rest->SetAuthGoogle($authGoogle);

// Chilkat's sample data (pig-rescue data) is publicly readable at: https://chilkat.firebaseio.com/.json
// This data is publicly readable, but not writable.  You'll need to 
// run against your own database..

// We're going to update "Molly II" to "Molly III"
$pigNameUpdate = new CkJsonObject();
$pigNameUpdate->AppendString('name','Molly III');

// The string content of the last arg passed is  {"name":"Molly III"} 
$jsonResponse = $rest->fullRequestString('PATCH','/pig-rescue/animal/-KI3bD-FU_Dake7sYOiP.json',$pigNameUpdate->emit());
if ($rest->get_LastMethodSuccess() != true) {
    // Something happened in the communications (either no request was sent, or no response was received.
    // (The Chilkat REST API also has lower-level methods where an app can send the request in one call,
    // and then receive the response in another call.)
    print $rest->lastErrorText() . "\n";
    exit;
}

// Check the response status code.   A 200 response status indicates success.
if ($rest->get_ResponseStatusCode() != 200) {
    print $rest->responseStatusText() . "\n";
    print $jsonResponse . "\n";
    print 'Failed.' . "\n";
    exit;
}

// When successful, the response contains the data written.
print $jsonResponse . "\n";
print 'Success.' . "\n";
