PHP Course: Variable concatenation?

Question

Did I miss the exercise where it shows you how to add to strings together? I keep seeing " .$var . " inside of the tutorials, but for the life of me I can't find where they mentioned it.

I'm currently on pre-assigned Variables(_SERVER, etc) and I swear I haven't seen it yet. Or is it not mentioned until later?

Answer 1

In Variables -> Data Types they mentioned use of string concatenation operator. Rather as a little note though.

Answer 2

Yeah I kinda wondered about it too. Well I guess they kept it in little dose in order not to cram new coders with too much new info 😁

No worries, I almost lost it on the way too hahaha

Answer 3

Ohh! Haha, thanks much! I understood what it's use was for but thought I was loosing my mind when it came to the actual "exercise" 😂
