Is there harm in outputting html vs. using echo?

Question

I have no idea really how to say this, but I can demonstrate it:

Content Title\";
}
?>

Answer 1

There are no relevant differences performance-wise. But you won't be able to use variables in the latter, and it looks less clean IMO. With large blocks, it also becomes extremely difficult to keep track of {} structures.

This is why the following alternative notation exists:

Content Title

it's marginally more readable.
