Short echo not defined

<?=$xy?>

should be declared as wrong

<?= $xy ?>

should be the one we are looking for
spaces issue

To elaborate a little more on the issue.
Currently this is considered valid syntax by our code style:

<?="some string"?>

It is much nicer to have it with surrounding spaces:

<?= "some string" ?>

Also, notice for further issues: elaborate more on a problem, or we are gonna get set of unclear issues.

it is funny how the dollar something gets eaten so it looks confusing :D try to edit to see my comment

It's actually markdown behaviour.

For code snippets, use
```php
some code
```

Otherwise, markdown parser will try to parse <?=?> as ?=? tag and, since it is non existing, it will be stripped out :)

true story, edited :)

Agreed. Can we get a phpcs rule for this?
