Will Installing MySqli have any effect on old sites?
We have a server with WAMP installed, we have a freelancer developer that has programmed with MySqli in mind, however we haven't had this extension installed.
If we were to install this extension would it have any effect, at all, in the slightest with any SQL/PHP used on other sites on the server?
Probably not. Depends if there's any code that tries to use it (maybe something that does feature detection, like "try to use mysqli if present, otherwise mysql").
Try it in your test environment. You do have a test environment, right?
We do, I just wanted clarification before I install it tomorrow at the office.
Thanks for your feedback
