Dani I guess you forgot to delete the exclamation mark(s) on line 12

I wouldn't recommend using empty as it takes falsly values as empty (0, 0.0, null, false, etc..) but I get what you're trying to show of course.

Great video, as usual! It could have been a great opp to introduce shorthands tho - unless you already made a video about it already. Anyway, thanks for what you do! We need to keep PHP alive :)

Obviously there are sometimes cases where a small amount of nested conditionals are probably going to be perfectly fine, but for the most part, this method works really well.

This advice is so helpful my friend! Thanks for sharing this. I don’t get why ppl are complaining about your „errors“, as this video is about explaining a concept, not a specific piece of code. 😅

Hi Dani, once again a great video - I know I'm late but I'm reviewing what you did the last years and it is a pleasure!!! I am one of those nesters indeed and I wonder what to do when "if-elsing", what I commonly do when my nesting "happens". My workaround commonly was to extract such nestings into decision-functions. Often this can be useful as similar decisions can be made at several spots inside a project. Is there a way to jump right to the else condition? From my old C-programming times I remember people telling me that jumping points are no good way to programm. I guess thats only if you jump forth and back, do you agree? Best Christian

Dani, can you do us a file / image upload, retrieve, delete and update system in php on a live server? I think this almost doesn't exist on youtube. Consider it please. You are a great teacher again.

You are amazing teacher. Please make a video of how to build php for backend and javascript for frontend together as a fullstack, so we could know how frontend and backend integrates .... There are very few videos out there, that have both js and php included project.

Most nesting, in C/C++, is actually from maintance mode, where the desire, is to change the code the least, but have the new condition. After a few years, you'd added 20+ more conditions (lol). There is one piece of code I remember, that had no validation. The validation occured before it was called. But then things changed. After three years, I'm looking at 3 years of trivial changes, thinking, I would not have done it this way from the beginning. I added a java validation external program, and left the damage in place. But, it got weird. One week at a time. 600+ companies exchanging files, and someone can argue the definition of zero.

Keep your code lean and mean. Negation is key here 🙂 I always say to friends & family, don't be so negative, but if you're actually in coding mode, you want to be very negative at times.

@basicbeaver 11 ай бұрын

Is it a good practice to use so many global variables, though, since all the variables are now in the global scope and not inside an if condition?

@darvinde 9 күн бұрын

3:48 No, exit and die are exactly the same like aliases. In other languages they differ, but not in php.

I have a legacy project built using a "true Indian coding guidelines": with a nesting level up to 6, and files length up to 5000-8000 lines (20-40K). I hoped, you'll show some ingenious "hack" to solve the nesting ifs' problem, I can utilize, but unfortunately, I know "the catch" which is on your video for quite a time :)/

Dani, there is an error in the code: we need to check if empty, not if is not empty

In the line 3, shouldn't you use another set of brakets after the exclamation mark? if(! ($_SERVER ..... === "POST")) Or simply use !==

I don't even understand this code... I think it will cause redirect loop (in case of GET request), because the script is already runs in index.php file.

Sir, do you have something against birds?? If I'm not allowed to nest then I can not make mini 🦅 😢 Callback hell is just as worse 😂

But by this implementation we introduce duplicates in the code for each curly block about the header and exit. It will be very helpful if you give me another solution for the duplicate removal for sem implementation

@Dani_Krossing Ай бұрын

The duplicate is done on purpose, since it allows us to include separate error/success messages into the URL, when we send the user to a page.
