Q: Farmer, Wolf, Goat and Cabbage Problem: full decision tree in C

Country BoyI put a backtracking algorithm around the Farmer, Wolf, Goat and Cabbage problem - to see if there are any interesting branches, besides the (two) 7-step solutions. On first view it seems a dilemma. Then you realize it can be solved (by taking the goat back at step 4). Then you realize: it can al...

Q: Client-server application for logging running processes

I'm not a PHP expert, but it looks like the theme is applied in the web environment but not via CLI. Is that correct?
Are there other differences?
Might it be possible to pass in a variable indicating the desired context?
Der Kommissar
Der Kommissar
@FranciscoNúñez The problem here is that you want the script to dynamically choose it, when the normal reality is to build three scripts: 1) the core functionality that abstracts the concepts (and in your case, returns things like comment: <comment text>); 2) the web-wrapper which digests the core output and formats it for web; 3) the CLI-wrapper which digests the core output and formats it for the CLI.
Francisco Núñez
Francisco Núñez
I am making improvements to the highlighting and one of the points; is that it can be used both by CLI and by a browser ... but I don't know what is more convenient if doing it separately; then I have an output() method; and another output_cli() or implement a single output() method and within this determine if it is cli with php_sapi_name() === 'cli'
Edward
Edward
14:47
Maybe output(cli) and output(browser)?
Leave it up to the user to specify the context instead of having the library attempt to determine it.
I think that would also simplify testing.

There's no technical reason one should not be able to emit HTML from the command line. I might, for instance, redirect it to a file.
Der Kommissar
Der Kommissar
You can eliminate the ini_set by emitting full HTML instead of relying on the auto-PHP HTML, which you should do anyway because technically PHP INI stuff is an outside dependency you have no true control over.
Of course you can't do that if you're using var_dump, so you'd have to do it yourself.

This is Stack Overflow and not Code Review. You should post your question over there.

It seems you mixed up some responsibilities. Also CRUD operations in view model sounds not good. This is model logic.
