Furthermore, this function returns 'stream' on php 4.3 on windows & linux.
You if you want to differentiate between a file resource and other stream resources, as stated before stream_get_meta_data() gives you an array which, on my system, contains the following elements which might suggest a file handle:
[wrapper_type] => plainfile
[stream_type] => STDIO

However I've only compared this to a stream from a url, so I include this only as a suggestion.

In PHP5 (on Linux), the above example identifies the "file" handler as a 'stream', not 'file'.

This can be particularly worrisome if you're trying to determine the type of stream using this function.

The alternative is to use <?php stream_get_meta_data() ?>, which returns an array containing "stream_type (string) - a label describing the underlying implementation of the stream."
