PHP Sample To Upload File

  • Before you try this code, make sure you have installed PHP cURL,
  • This sample uses FileCloud APIs "loginguest" and "upload"
  • This code creates custom upload form doing a single shot upload
  • This can be modified for multiple uploads as well
  • The code can upload files with same name as input or a custom name.
  • The following sample reads a file named helloworld.txt and uploads into FileCloud as hellothere.txt
