Question for those who know about loading modules

I just want to sum up this new concept to me and make sure I get it Instead of reconfiguring php, or using dl function, I can just A.) go to php.ini, and under extensions_dir type: extension_dir = /usr/lib/php/extensions/no-debug-non-zts-20000401 B.) Under that, I list the modules I want to load, assuming they are in the non-debug-non-zts-20000401 directory. Such as extension=module.so extension=othermodule.so C.) Save php.ini and then restart apache D.) Use the script that uses that module as I normally would if I were to reconfigure php Yes or no? lol I want the experience to load modules, so it's important that I learn, so I ask. PHp.net I couldn't find confirmation that this is the procedure and I've asked everywhere. Thanks Joel
