You forgot an opening bracket, and need to quote the regex, like
if (ereg('[^0-9]', $num))
print "That's not a number!";

You need to tell the browser to create a newline when displaying HTML:
echo "HELLO<br>WORLD"
will look identical to
echo "HELLO<br>\nWORLD"
You can also use the nl2br() function to convert all newlines to a line break:
echo nl2br("HELLO\nWORLD");
If you display preformatted text you'll see the linebreak:
echo "<pre>HELLO\nWORLD</pre>";
