By default, PHP sends out HTML headers. Browsers ignore extraneous
white-space characters, and also new lines, carriage returns and tabs,
converting them all to a single space character.

If you view the source in your browser, you'll see the newlines, but in
regular display, your text is treated as HTML.

There is a function in PHP called nl2br, which accepts a string and
returns the same one with all the newlines replaced with <br>
automatically, which might be easier to use if your content is in a
string. Otherwise, the only way to get new lines on your actual page is
to either manually use <br> tags, put the text inside a <pre> block, or
use CSS to preserve the white-space.
