When do I use if/endif versus If{}?

Question

Well the question is self explanatory.

In PHP when do I use the if/endif notation instead of the standard if(something){} notation?

Exa

Answer 1

I mostly use if/endif when stopping and starting the php code block in between, so nearly always when raw html is being outputted.

For example:

Lorem ipsum.

This looks, at least in my opinion, better than the following:

Lorem ipsum.
