isset

one thing i like about Codeigniter is that I can write pure Object Oriented php in a class of my own, with its member properties and methods ,  and then its easy to utilize with CI4.

I have a small number of my own php class and a couple of webs that are live; i've had no security or other problems due to using pure php. With some frameworks you get a choice of either pure php or framework slant "template language "  like {{ @name }}  in a view. I don't think there is that in CI4.

So the short answer may be, not only is isset() ok but actually  the only way of doing things is with "proper OOP php" of course due to ignorance i may be wrong :^)


in fact if you look at some of the core classes it all looks nicely pure php to me

thank you so much
