I deployed a Symfony2 application on my server and I wanted to disable some php functions but I don’t know if I can or not.
But I can’t find any informations.
Should I just try to disable a function and look Symfony reaction ?
Or do you know any list or informations about unused php functions in Symfony2 ?
No.
No such list is published.
I think you can safely disable functions which are usually under the control of the old PHP safe mode. As a contributor of Symfony 2, I might be able to ask more precisely to your question, if you give us some details about the functions you want to disable.
