What is it that *actually* want to achieve? If you want to keep the state of objects for some time then you an store that in persistent allocated memory buffers and extend zend_object with a pointer struct my_object { zend_object inner; custom_data *ptr }; and then use the property hooks to "emulate" properties and accessor methods as your API should look like. Your MSHUTDOWN then has to handle the final cleanup of the data. Mind that for many deployment models of PHP request-surviving objects (like ASP's Application object) aren't a good architectural choice as PHP can live in CGI context (where there are no recurring requests), in FastCGI context (where there are recurring requests to multiple parallel processes), in IIS/apachempm/etc context (where there are multiple threads doing this in parallel) and multi machine context where recurring requests may hit different machines ... having a cheaply serializable format often is better. johannes
