Right now you have to serialize the object yourself if you want to cache it, but I will add code soon to do that automatically internally. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP] serializing result sets or what?
Thanks, that looks good. But what do I do if OS is WinDoze? The install of the pecl only gives a .so *feeling sorry not everything runs on xp* ... I will take the time to benchmark the serializing vs db calls ... is there a good benchmark tool out there (without having to use microtime inside the scripts)?

A very similar question was asked recently on this list. You might like to consider caching whatever you create from those result sets rather than the result sets themselves, but APC [1] is worth looking at as I believe it can cache (some?) PHP vars without serialisation, using apc_store() and apc_fetch(). The only way to know whether such a scheme would help in your specific situation is to benchmark. Go on, it won't take long!

I thought about serializing the data and then caching it (with Cache_Lite - maybe there will be a future inclusion of such a caching scheme into the php core or pecl?). I was not sure about performance though (no time for benchmarking this). The issue is that as this system grows we get 2 - 3 db calls on the server (which is too much in my opinion), but will serializing be cheaper or simply the lesser of two evils? A very similar question was asked recently on this list.
