nucoder "Warning: indirect function call"

While encoding a project based on slim framework, I got "Warning: indirect function call".
I found no documentation about this message, and what to do in this case.
Endeed, the code calls a function via a variable.
Is it prohibited to encode safely?


Thanks for your support.

It means that you have to take care and check that code carefully after encoding.
For example if you assign the variable with a name of your own (user-land) function and the function is obfuscated, php won't find it and you'll get function not found fatal error.

Thanks for the answer.

Just to be certain-->
It is a controller. say I have
class mycontroller {

function get()
{
}

call()
{
$this->$action();
}
}
This seems to work fine when $action == "get"
And I use default option for "Obfscated names" (auto)

should I use call_user_func()? I suspect the risk is identical.

In the end, even if apparently it works, I should set nucoder to avoid obfucation on controllers?

(in fact, I just checked, I use nucoder in command line & I pass < --obfuscation 1 > - I don't remember what it means)
