[MEGAPATCH] stream filter improvement View as Markdown

Hi,

The attached patch allows stream filter implementations to accept
the parameter as a zval rather than a string.

For practical example, you'd be able to pass parameters to strip_tags
filter in a couple of ways, like:

a. stream_filter_append(STDOUT, "string.strip_tags",
PHP_STREAM_FILTER_WRITE, "<script><body>");

b. stream_filter_append(STDOUT, "string.strip_tags",
PHP_STREAM_FILTER_WRITE, array("script", "body"));

And this patch could also reduce my redundant codes in
ext/standard/filters.c, so I hope this feature will be introduced in any
way even though the patch would be actually bogus.

Any comments are welcome.
