(PHP Extension) Upload Binary File from Memory

This example demonstrates how to upload a binary file from memory. It uploads the file to a subdirectory of our choosing.

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");

$success = true;

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

// This example uses a previously obtained access token having permission for the 
// Google Drive scope.

$rest = new CkRest();

// Connect using TLS.

// Provide the authentication credentials (i.e. the access token)
$rest->SetAuthGoogle($gAuth);

// -------------------------------------------------------------------------
// A multipart upload to Google Drive needs a multipart/related Content-Type
$rest->AddHeader('Content-Type','multipart/related');

// Specify each part of the request.

// The 1st part is JSON with information about the file.

$json->AppendString('mimeType','image/jpeg');

// To place the file in a folder, we must add a parents[] array to the JSON
// and add the folder ID.  
// In a previous example (see Build Local Metadata Cache
// we built a local cache to make it easy to lookup file IDs given a file path.
// Let's find the file ID for the folder "testFolder/abc/123"
$gdCache = new CkCache();
$gdCache->put_Level(0);
$gdCache->AddRoot('C:/ckCache/googleDrive');

// parents is a CkJsonArray
$parents = $json->AppendArray('parents');
$parents->AddStringAt(-1,$folderId);

$rest->SetMultipartBodyString($json->emit());

// The 2nd part is the file content, which will contain the binary image data.
$rest->put_PartSelector('2');
$rest->AddHeader('Content-Type','image/jpeg');

$fac = new CkFileAccess();
$jpgBytes = new CkByteData();
// Read a JPG file from the local filesystem.

// A successful response looks like this:
// {
//   "kind": "drive#file",
//   "id": "0B53Q6OSTWYoldmJ0Z3ZqT2x5MFk",
//   "name": "hedgehogs.jpg",

// Get the fileId:
