It sure has to be - I simply haven't contributed to the documentation project for about a year now, so I wasn't the one who wrote the documentation for that function... > I'm afraid I don't quite follow what you mean, maybe because I'm not sure > what exactly is zval.

With PHP 3.0 - things were relatively easy - there was indeed just one zval (or pval) for each object, more or less. With PHP 4.0, things are much more efficient, but at the same time - much more complicated. A hundred objects may share the same zval if they point to an object that looks the same. And under some circumstances, that zval may split into two zvals, and 99 objects will point at the original, while the 100th will point to the duplicate. > I guess you mean that it would have to be the maintainer of the XML support > module (Stig?) to learn how to do that from your register_shutdown_function > example and add such kind of support, right?
