Here's what's wrong (or part of it): by writing "module global" I meant a variable, which is common for all processes/threads, in which PHP extension code is being run. Think of some common resource, which must be initialized just once and accessed through a single class instance, no matter how the extension code is executed! (and that class instance may contain no zend engine structures) How should it be done? Any examples? > PECL/rar is in C++ (more or less). Thanks!
