  • This sample does multi-chunked uploading.
  • Before you try this code, make sure you have installed PHP cURL,
  • This sample uses FileCloud APIs "loginguest" and "upload".
  • This code can be used to upload large files, splitting them into 20MB chunks.
  • The following sample reads a file named sample.mp4 and uploads it into FileCloud as sample.mp4
