Well, there's some docs but they do not cover internals too much. If you
have specific questions - ask them.
ZTS means if PHP/Zend is built in threading environment (like for IIS) or
not (like httpd). The difference is that in the former case memory space
can be shared between number of execution threads, so special care should
be taken.
*_FETCH() "fetches" (i.e., makes available in current block) the
set of per-thread globals for given module. These globals are defined in
zend_globals.h for Zend and module headers for all modules. Generally,
every global variable you modify should be per-thread global, unless you
explicitly want it to be shared between threads - and then you should
lock/mutex it, etc.
In the non-ZTS mode most _FETCH functions are defined to do nothing, since
using plain old globals is OK.
