(PHP Extension) Azure Storage: Upload Binary Data to Block Blob

Sample code to upload binary bytes to a block blob in Azure Cloud Storage. This creates the block blob, or replaces an existing block blob.

Note: The maximum size of a block blob created by uploading in a single step is 64MB. For larger files, the upload must be broken up into blocks. There is another Chilkat example for that..

<?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");

// Azure Blob Service Example: Upload binary bytes to a block blob.
// This creates a new block blob or replaces an existing one in its entirety.
// See also: https://msdn.microsoft.com/en-us/library/azure/dd179451.aspx

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

$rest = new CkRest();

// Connect to the Azure Storage Blob Service
$bTls = true;
$port = 443;
$bAutoReconnect = true;
// In this example, the storage account name is "chilkat".
$success = $rest->Connect('chilkat.blob.core.windows.net',$port,$bTls,$bAutoReconnect);
if ($success != true) {
    print $rest->lastErrorText() . "\n";
    exit;
}

// Provide Azure Cloud credentials for the REST call.
$azAuth = new CkAuthAzureStorage();
$azAuth->put_AccessKey('AZURE_ACCESS_KEY');
// The account name used here should match the 1st part of the domain passed in the call to Connect (above).
$azAuth->put_Account('chilkat');
$azAuth->put_Scheme('SharedKey');
$azAuth->put_Service('Blob');
// This causes the "x-ms-version: 2021-08-06" header to be automatically added.
$azAuth->put_XMsVersion('2021-08-06');
$success = $rest->SetAuthAzureStorage($azAuth);

// Note: The application does not need to explicitly set the following
// headers: Content-Length, x-ms-date, Authorization.  These headers
// are automatically set by Chilkat.

// IMPORTANT: Make sure to set the x-ms-blob-type header:
$success = $rest->AddHeader('x-ms-blob-type','BlockBlob');

// For this example, we'll just load a JPG file into memory..
$binaryData = new CkByteData();
$fac = new CkFileAccess();
$success = $fac->ReadEntireFile('qa_data/jpg/starfish.jpg',$binaryData);

// Note: The maximum size of a block blob created by uploading in a single step is 64MB.  
// For larger files, the upload must be broken up into blocks.  There is another Chilkat example for that..

if ($rest->get_LastMethodSuccess() != true) {
    print $rest->lastErrorText() . "\n";
    exit;
}

// When successful, the Azure Storage service will respond with a 201 response status code,
// with no response body.

if ($rest->get_ResponseStatusCode() != 201) {
    // Examine the request/response to see what happened.
    print 'response status code = ' . $rest->get_ResponseStatusCode() . "\n";
