(PHP ActiveX) Azure Storage: List Blobs

Azure Storage Blob Service REST API: Sample code to fetch the list of blobs in the specified container.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

// Azure Blob Service Example: List the blobs in a specified container.

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