tempnam
~~~~~~~

.. versionadded:: 2.7
The ``tempnam()`` function was introduced in Symfony 2.7.

:method:`Symfony\\Component\\Filesystem\\Filesystem::tempnam` is a drop-in
replacement for PHP's builtin :phpfunction:`tempnam` function which allows
you to create a temporary file on a stream if the stream is writable. It
returns false on failure.

$tmpFile = $fs->tempnam('ftp://example.com/tmp', 'FOO');

``$tmpFile`` will be the name of the temporary file or false.
