Confused about using DL function

[Anon]

I tried the manual, but I must ask, I sometimes get confused with this function

Where is the .so file going to be located in order to get Dl("module.so"); to work?

I believe if I want to add module.so functionality to php, without recompiling,
I add them in the extensions_dir path ni php.ini and restart apache

But with dl, what do I do differently to get it to work?

And what effects are there on server performance?

I just get confused...where should the file be in order to use DL, assuming I don't want to reconfigure, or just load extensions dynamically

:?

The file must be in the extensions_dir pointed by the php.ini file.If is commented in the load_extensions section (has a ";" mark in front) then you can load'it when you need'it with the dl() function.
supoose you don't have the gd extension loaded and you need'it in some script,you can load that in your script.
If you ron on linux :dl("gd.so") ,if win:dl("gd.dll")
That's it.
Hope to help.
