general enquiry about use of php tmp dir

[QuiddyBiddy]

when i use flash to upload an image to my php script, it sends it as an 'application/octet-stream'.

 

i tried to read from the $_FILES['Filedata']['tmp_name'] element to read in the file contents to a string.

 

 

however this would not work as it could not find the file. Searching manually through the dir to my allocated temp dir i could

not find the file either.

 

i also tried reading from [HTTP_POST_RAW_VARS] and the (://input) one, to no avail.

 

I knew it had to be there because i could echo back the name, temp_name and size.

 

Hoewever, when i used move_uploaded_file(), and pass through tmp_name, it was able to read the file and save it in a new location which i could now see the image.

 

What is happening here?
