I am trying to add a custom PHP extension (as a DLL) on Windows, but the extension does not load. Why is that?
Before trying to add pre-built binary extensions on Windows, please make sure that the extension is built for the PHP version that is shipped with Zend Server, that it is not a debug build, and most importantly, that the extension is compiled in non-thread-safe (NTS) mode. Extensions compiled with thread-safety enabled will not work with Zend Server. Please note that Zend does not support custom extensions, and that before submitting any support requests, you should disable any custom extensions that you have added.
