Will search engines index this site?

Question

Search Engine Optimization

Hello.
Guys, for many, the question will probably seem stupid, but still.
I create a website and make it multilingual. All words will be stored in the database.
And accordingly will be substituted so.
Example:

<meta name="keywords" content="<?php echo row['keywords']?>">

Will Yandex collect keywords from such a site?

Answer 1

1) search engines have scored on keywords for 5 years already
2) the search engine sees the already rendered HTML, so it will see everything

Answer 2

Yandex will see the generated HTML. You will see the same HTML if you open the page in a browser. What is going to be there? <?php echo row['keywords']?>or a line with words?

Answer 3

Will Yandex collect keywords from such a site?

For many search engines, keywords are not the main factor. Even with their complete absence - everything works fine (tested).
If you have keywords instead of a PHP tag, then everything will work as expected. But, even if this tag is there (as it is written now) - it will also work, it’s just that the keywords will not be exactly what you expected, apparently ... (i.e. the keywords will be specifically this writing :) <?php echo row['keywords']?>_
