What can be used to make mobile applications?

Question

Mobile development

The crux of the matter is as follows.
How are mobile applications for android and ios made? Let's say a person knows js (react), html, css.
Is it possible to make a mobile application using these technologies? Or do you need something else?
For example, is it possible to use php or its frameworks? How are requests sent to the server ? How is the database there? In general, the question is what kind of technology stack is needed, if we take only native tools.
