Tutorial-First-Application VS php-docker

b) Separate out all SQL and PHP database code. Put these in separate classes similar to this example Slim First Application Mapper class. You can decide later if you want to use a framework's DB code or not - it would be simply refactoring your existing code and not changing (hopefully) the API that you started using internally

Yes, as an example, the First Application's business logic (not that it's much) doesn't tie itself to the framework, as one example. Odan's Slim Skeleton, ADR Example (yes, I know you are the author), and the Aura Payload example class can be seen as other examples.

Both. Build business logic with PHP, then use a framework for the common functionality (routing, auth, validation, etc). Look at Slim's First Application to show a very simple example of this - https://github.com/slimphp/Tutorial-First-Application

Another option, to me and speaking to the OP as an alternative, it is simpler to add some Data Mappers/Repositories to abstract away the Database code. Good examples is the sample ADR application, Payload library example, Slim 3 First Application, or this Slim 4 Skeleton application

Yes, you can. Did you look at the example I provided? Want another one? Slim Framework's first application does exactly this:

Yes, the apache[0] image will do what you want

That's the first I've heard of it, and I like it! I can't tell you the number of trips to php.net to look at argument order for a function. Is it haystack/needle, or needle/haystack? Of course it could turn into the same thing w/ argument names (is it whole_name or full_name?), but I'm going to use it.

Prepare to spend a fair bit of time reading and going back to phptherightway.com and php.net. I've also found this Tutorial from Envato Tuts+ to be quite good.

All I want to do with php is to have a recurring navbar on a website. I don't know what to do next. So far I've tried php.net's manual, w3scchool's tutorial and the set up part of first five recommended php tutorials on youtube. I have also spent hours on stackoverflow, which got me even more confused. The more I read, the less nothing makes sense to me and I don't know where the problem is.

I tried looking at the upgrade from 7.4 to 8.0 docs on php.net but I don't see anything regarding any changes to this function. Any ideas?

Does anyone else have trouble getting into php.net without some human verification page popping up first?

I've gone to php.net probably thousands of times over 15 years and have never seen this. If I saw it, like this user did, I'd be curious.

I would but cannot access php.net because of blue hardware

Not necessarily, a docker image can build from source. In fact, the official PHP docker image is built from source. See https://github.com/docker-library/php/blob/master/8.2/alpine3.18/cli/Dockerfile

. php.net is the official documentation
