(PHP ActiveX) 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 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.

// See Global Unlock Sample for sample code.

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