Please provide us with the following information:

- [x] bug report -> please search issues before submitting
- [ ] feature request
- [ ] documentation issue or request
- [ ] regression (a behavior that used to work and stopped in a new release)

Minimal steps to reproduce

run the application/file phpQS.php

Any log messages given by the failure

none

Expected/desired behavior

the file HelloWorld.txt uploaded to Azure Blob storage should have the text "Hello Azure!" in it, but it is empty.

OS and Version?

Windows 7, 8 or 10. Linux (which distribution). macOS (Yosemite? El Capitan? Sierra?)

Windows 10 Professional

Versions

Mention any other details that might be useful

On line 84 in phpQS.php the call to open the file in "write" mode will essentially truncate the file contents (http://php.net/manual/en/function.fopen.php ):
$myfile = fopen($fileToUpload, "w") or die("Unable to open file!");
Thus when the file is subsequently uploaded to Azure it will be empty.
Since the intention is just to see if the file exists/can be read, the fix would be to use the "read" flag on line 84:
$myfile = fopen($fileToUpload, "r") or die("Unable to open file!");

Thanks! We'll be in touch soon.
