How to read code from Azure Blob storage in to PHP?

I have a WordPress plugin that reads and displays image files from the plugin folder, the plugin reads and displays the images name from a CSV as there is almost 200+ files. Now the client wants to migrate the images to Azure Blob storage.
The current code looks like below.

‘<div style=”background-image: url(‘+csvData[‘logo’]+’)”>’ +
‘<div style=”background-image:url(‘+csvData[‘banner’]+’)”></div>’

Can you please help me how to implement this in PHP? I have seen in an example to implement as below

$storageAccountName = 'name';

$accessKey = "xxxxxxxx";

$containerName = 'test';

$blobName = 'sample.png';

However in this case the $blobName cannot be defined as there is 200+ files in Container. The images need to display at multiple locations.

The files are private (no anonymous access).

Thanks
