Re: Re: cvs: php4 /ext/standard filters.c

With the current model, the concept is that you can use either the filter name or filter parameters to distinguish the ultimate behaviour. Yes this is a possible headache. I am thinking that two separate chains of filters (one for reading and one for writing) might make this situation a little easier; this way you could have a filtered read stream but leave writing unfiltered etc. --Wez.
