PHP Warning: Module "FFI" is already loaded in Unknown on line 0

Description

i've changed the ffi settings to:

extension=ffi
ffi.enable=true

and this is causing this error:
PHP Warning: Module "FFI" is already loaded in Unknown on line 0

and i've changed these values both in cli and web

It's likely that the module was already loaded by another ini file. You can file the list of loaded ini file with php --ini.

i saw that with that command that on debian this is enabled by default in the cli ? you might need to check the documentation, so with this extension we can adjust the php code too ?

Yes it looks like that on Debian the extension is enabled by default when it's installed. I'm closing this as it doesn't appear to be a bug.
