#012433: Allow objects to be stored

APC and Memcache already allow objects to be stored. APC actually stores objects better than it stores arrays. This would only be needed for the file storage methods.

using serialize() with file storage also has a huge problem with charsets: serialized data cannot be converted from/to utf8 and the deserialized back. Not a huge problem for mem caches, but if you store stuff in files, it might live longer than expected...

Isn't JSON a better option then php serialization with respect to unicode strings?

#256987 by Paul Borgermans on June 7th, 2008 [Permanent Link]

Well, you do not store string length, so you can utf8encode/decode and be fine with it...

...otoh json is by definition UTF8, so anything else will not qualify.

The json_encode (and decode) php function are pretty fast, being based on a state machine hand-coded in C...

...otoh it is assumed that the php data to be encoded is in utf8 already. If it is not, you have to run it through utf8_encode, and it might slow things down quite a bit

We'll go for using PHPs var_export() to realize this and provide an interface ezcBaseExportable to indicate that objects can be stored. Such objects will then be enabled for being cached in certain file storages.

Besides checking for ezcbaseexportable, I think it would be nice if the serializer also called magic functions sleep and wakeup on the objects it stores.

It makes it easier to serialize recursive objects / objects with resources, and fits in with the overall php way of doing things.

In fact we could even check: if a class has _sleep and/or __wakeup, we can assume it is serializable, without introducing our own interfaces - making it easier to use classes from outside ezc!

Implemented in rev. #10650.
