Is there a way to do load/startup time inclusion? you could put it in your php ini file extension = foo.so then I believe the impact will be on the first instance for that php engine. so in fastcgi mode, you'd only have the hit once every PHP_FCGI_MAX_REQUESTS when the child restarts... Have a look at a standard Mandriva or Fedora/CentOS PHP install. You'll see that the various parts of the PHP engine are all very modular with several PECL modules pre-built for your convenience. The php.ini file is split into files in /etc/php.d/*.ini so that the packages can put their own little config systems into the php.ini file without dicking around with automated editing. When using PHP as a module the impact is pretty low, only once per restart. As Mike wrote the low impact is also apparent in FCGI mode too (but it's a bit more obvious where the extra load it creates is manifested). Personally, the convenience of modularity sells this approach for me. I do generally roll my own RPMs to keep things up to day and patched, but again I just use that format/deployment method as it's convenient.

I think you need to create a .so file, not .o and .la...

However, I cannot seem to suceed even at the simplest module, the one provided by ext_skel. I run buildconf, configure and compile the module, however dl() won't load the resulting .o, libmodule.la saying the file format is invalid. If I manually link the object file to a shared library, dl() will tell me the library is invalid. So I'm stuck. If someone could help me that would be gratly appreciated. I'm using FreeBSD 4.3 and the (patched) PHP sources from the ports tree. Thanks.
