I've been doing some work with some of the symmetric Filters - especially encryption and urlencoding. What I've come up with is a more 'formal' class which encompasses and encoder and a decoder.
The idea is that for the same Zend_Encoder based class, encode->decode should be just an identity to the value passed in. (given scalar $x, $params to Crypt;) $enc = new Zend_Encoder_Crypt($params); $y0 = $enc->encode($x); $y = $enc->decode($y0); assert($x === $y); An Encoder could easily be just a composition of Filter objects. Encoder chaining would run encode() in the order specified in the chain, but decode() would run in reverse order. $enc->addEncoder(Zend_Encoder_Base64) $enc->addEncoder(Zend_Encoder_UrlEncode); $enc->encode(); // runs Base64->encode(); UrlEncode->encode(); $enc->decode(); // runs UrlEncode->decode(); Base64->decode(); Is this a valuable class? If so, I'll happily put together the proposal and start up some basic implementations. -- View this message in context: http://n4.nabble.com/idea-Zend-Encoder-tp1750941p1750941.html Sent from the Zend Framework mailing list archive at Nabble.com.
