Bug #27619 (filters not applied to pre-buffered data)
--FILE--
<?php
$fp = tmpfile();
fwrite($fp, "this is a lowercase string.\n");
rewind($fp);
/* Echo out the first four bytes 'this' without applying filter
Remainder will get sucked into the read buffer though. */
echo fread($fp, 4);
stream_filter_append($fp, "string.toupper");
fpassthru($fp);
?>
--EXPECT--
this IS A LOWERCASE STRING.
