get_defined_vars
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.
get_resource_type
(PHP 4 >= 4.0.2, PHP 5)
get_resource_type — Geeft het resource type terug
Beschrijving
string get_resource_type
( resource $handle
)
Deze functie geeft een string terug die het type van het resource weergeeft. Als de paramater geen resource is, zal het een foutmelding genereren.
$c = mysql_connect();
echo get_resource_type($c)."\n";
// print: mysql link
$fp = fopen("foo","w");
echo get_resource_type($fp)."\n";
// print: file
$doc = new_xmldoc("1.0");
echo get_resource_type($doc->doc)."\n";
// print: domxml document

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."
