Why do i only get 1919 instead all the hundred years before?

<?php
$currentYear = date('Y');
$year = $currentYear - 100;

while (++$year <= $currentYear) {
  echo $year . "<br /<\n";
  $year++;
}
?>

nope. yours to mine, is the same in terms of your first edition, generally, if you read my notes, you'd be able to do it, my notes are commented issue is in this line

<?php
echo $year . "<br /<\n";
//it has to be like the below
echo $year . "<br />";

Ok silly me, didnt see the echo at the end of the line haha. Now it works but im a bit confused because in the video Alena writes both line break they even discuss this on another question here :https://teamtreehouse.com/community/why-do-i-need-both-br-and-n

because, you have got an error

<?php
$currentYear = date('Y');
$year = $currentYear - 100;

while (++$year <= $currentYear) {
  echo $year . "<br /<\n"; // here is the error , try this, echo $year . "<br />";
  $year++;
}

//by the way, you will not be able to see, 100 years, instead 50 years only, as you are incrementing by 2
//which in return will skip every alternative year.

?>

yeap, you could use both together

not like the way you have used, cause, I think there is a type, closing bracket for br is mistaken with another opening bracket.

<?php

//your way
echo $year . "<br /<\n"; 

//the correct way
echo $year . "<br />\n";
