Stop Doing This in PHP... | Avoid Nesting If Statements | Better Coding Habits in PHP

In this video I will show you how to write clean code in PHP, when it comes to conditions. You will learn how to avoid nesting if conditions, to get better coding habits in PHP. Better coding practices is something we should all continue to get better at, so hopefully this tip will give some of you something useful.

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

The best php teacher thanks alot mr dani complete please and upload more videos

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.

Back to PHP. You are a great teacher sir! Well done sir

[cryptoknight]

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 :)

[Lyrik-Klinge]

As usual very interesting, THANK you!

[MyCodingDiary]

Your videos are always so informative and well-presented. Thank you for sharing your knowledge with us!🚀😎

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. 😅

[PicSta]

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.

[javabeanz]

I know it's just a quick demonstration of the concept, but I would think that you would want to test if the SERVER variables were empty, as trying to assign them when they are not there would get errors. I know, because I have had that issue with my own code previously.

[Hefss]

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.

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.

[mortwain]

Thnx for this amazing video, Can you explain us that how can we do an image and a video upload, insert, delete, select from database

[Alexifeu]

3;48 From what I have read from multiple Website, Die and Exit are basically the same

[samnako]

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.

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.

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

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

[towndwarf]

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 :)/

[KwonDo-Hyung]

Would it make sense to create external validation classes for certain conditions, that could eventually move to a parent class to make them accessible elsewhere?
