(PHP Extension) Azure Blob - Get Tags (Check if Blob Exists)See more Azure Cloud Storage ExamplesGets the user-defined tags for a specified blob. This can also be used as a way to check to see if a blob exists. For more information, see https://learn.microsoft.com/en-us/rest/api/storageservices/get-blob-tags
