How often does it happen in practice?

Question

IT education

At the moment I'm learning php, namely: OOP, interfaces and traits. I recently learned that php has a page rendering feature (we create a method, say, render () and call it every time we want to display some php / html page). In my free time, I look through the vacancies of a php programmer, but I can’t understand how the work process itself will go, that is, I understand what the php programmer does in general and what functionality the php programmer is responsible for, but it’s still interesting if, for example, they will give me a task at the beginning "add a line with a phone number in the user profile and transfer it to the database", on what and through what will I perform this task, either through some kind of ready-made template, or is there already some kind of ready-made library / framework?
PS I started learning php immediately after html and css, please understand if I started to carry a fierce game at the end

At the moment I'm learning php, namely: OOP, interfaces and traits.

OOP, interfaces and traits are not directly related to PHP, these are general principles for building code.

I recently learned that php has a page rendering feature (we create a method, say, render () and call it every time we want to display some php / html page).

Cool, of course, you don’t need to know about how “rendering” happens, well, there is and there is ...

In my free time, I look through the vacancies of a php programmer

I hope that while this is purely academic interest, judging by the question, you don’t pull too hard on, say, an intern ...

if, for example, I will be given at the beginning the task "to add a line with a phone number in the user profile and transfer it to the database", on what and through what will I perform this task, either through some kind of ready-made template, or is there already some Ready library/framework?

On the computer through the keyboard will be. Perhaps there will be a ready-made template (I doubt that we are talking about the same "template"), most likely it will be some kind of ready-made framework, and even some functionality will be written on it (but this is not certain).
Read how modern PHP MVC applications work, see how popular frameworks work, try to do something basic on them, it will become clearer how everything works.
