In a lot of PHP tutorials, I have seen that the use of carriage return.

"/n" and "/r"

But Im very curious why we cannot just use echo "<br>" tag?

</div>

Answer 1

<br> is a new line in on a HTML page (an will display as such for the view on any web page). and are used more for the 'formatting' of the HTML code itself and will show on a single line for the viewer.

In a text area, however, or will show as a new line, whereas a <br> would not. or could also be used within strings for scripts that don't allow carriage returns such as javascript.
