tmpfile - Creates a temporary file

SYNOPSIS
       resource tmpfile (void  )

DESCRIPTION
	Creates a temporary file with a unique name in read-write (w+) mode and returns a file handle .

	The  file  is  automatically removed when closed (for example, by calling fclose(3), or when there are no remaining references to the file
       handle returned by tmpfile(3)), or when the script ends.

	For details, consult your system documentation on the tmpfile(3) function, as well as the stdio.h header file.

RETURN VALUES
	Returns a file handle, similar to the one returned by fopen(3), for the new file or FALSE on failure.

EXAMPLES

	      echo fread($temp, 1024);
	      fclose($temp); // this removes the file
