Where did I make a mistake in php (writing to a variable, displaying it on the screen)?

Question

PHP

I study php, I do elementary things. The problem is that if a variable in Notepad ++ is written by hand, then it is not read / does not work. It is difficult to explain in words, I made a special video. youtube.be/QjZoR9D702U

$hour = strftime( '%H' );
  $welcome = '';
  if ($hour > 0 and $hour < 6){ 
    $welcomе = 'Доброй ночи';}	
  elseif ($hour >= 6 and $hour < 12){ 
    $welcomе = 'Доброе утро';}	
  elseif ($hour >= 12 and $hour < 18){
    $welcomе= 'Добрый день';}	
  elseif ($hour >= 18 and $hour < 23){ 
    $welcomе = 'Добрый вечер';}	
  else 
    $welcomе = 'Доброй ночи';

<h1><?php echo $welcomе ?>, Гость</h1>
I want to understand what the problem is and not to face similar things in the future. But I lost time, for 2 hours I was looking for what the problem was.

Answer 1

Syntax highlighting hints that "e" is Russian.

Answer 2

The "e" in $welcome is Russian. Even the syntax highlighting says it all :-)

Answer 3

Even code highlighting on a toaster is smarter than your editor.
Install a decent IDE like PHPStorm. He will immediately identify such errors.

Answer 4

I posted a question and noticed that the "e" variable was added. It was me, through inattention, that I didn’t write “e” the first time and then added it. Maybe it somehow influenced? But the general code was identical.

Answer 5

As already mentioned above, there e is Russian, in order to avoid this, go to full-fledged IDEs, such as PHPStorm.
After a week of work, you will understand how convenient it is...
If you don't want an IDE, then use Sublime or Atom
