That's correct. You didn't ask PHP to write a <br> tag. You asked PHP to
write a newline break, which is exactly what it did.
So yes, your question 2) is what you would need to do, although your
question should read like this:
2. What is the prescribed way of inserting an *html* *newline* break*
*tag* into a PHP string? (Could it be printf("Hello world! <br>") ?
There is also the nl2br() function which converts "\n" to "<br />\n"
should you need to automatically need to do this with a string.
