function FileSystemInterface::tempnam
Creates a file with a unique filename in the specified directory.
PHP's tempnam() does not return a URI like we want. This function will return a URI if given a URI, or it will return a filepath if given a filepath.
Compatibility: normal paths and stream wrappers.
Parameters
string $directory: The directory where the temporary filename will be created.
string $prefix: The prefix of the generated temporary filename. Note: Windows uses only the first three characters of prefix.
Return value
string|false The new temporary filename, or FALSE on failure.
