Description:
------------
stream_filter_append() doesn't work for handles opened in 'x' mode, it would be helpful if the documentation was explicit about this (and any other modes it doesn't work with).

From manual page: http://www.php.net/function.stream-filter-append

But it is possible to append stream filters to streams opened in
'x' mode, e.g.

<?php
$filename = __DIR__ . '/70927.txt';
$stream = fopen($filename, 'x');
stream_filter_append($stream, 'string.rot13', STREAM_FILTER_WRITE);
fwrite($stream, 'hello world');
fclose($stream);
echo file_get_contents($filename);
?>

outputs:
