Does the site necessarily contain html files?

Question

Yii

An online store based on yii2, on the server found files of the format productview.php mainview.php, etc. for each page is this instead of html? I want to change some tags

Answer 1

is this instead of html?

It is difficult to say unequivocally without seeing your project, but it is possible. Only not "instead of", but "for". In dynamic sites, php generates html. Yii2 is built on the principle of mcv (model-controller-view) and probably the files you provided are views, if so, they contain logic and html markup.

Answer 2

Edit. We do not mind.
