I am trying to find the correct (or best) content type to pass to header() when outputting serialized PHP data. The best I could find when searching was a proposal for application/vnd.php.serialized and another person asking the same question without a definitive answer. I was considering using just text/plain and moving on. The data being serialized is an associative array, 1-3 levels nested. Values are always string/int/bool, in order of occurrence.
For reasoned I'd rather not get into, my application is using PHP4. Otherwise I would be using JSON and be on my way.
Edit: My question is not about how to work with JSON in PHP.
For those interested: I am handling JSON encode/decode using the 'Services_JSON' PEAR package , however I've noticed performance issues which PHP serialized resolves.
