these are so good. All the other videos I've seen feel like they're not teaching you at all they just show you that *they* can do it...

[waitajoseph]

I think your tutorials are the best. Finally, I know how to use PHP practically. I like the way you keep things simple, no complicating matters. Indeed, simplicity is the ultimate sophistication.

I have watch many php program But you are the only one why simplify for the lane you very much

*Expand this comment if you're a beginner who is confused.

*Note for non-beginner programmers: from within the local scope of a function, a global variable can only be accessed if you first write the keyword 'global' before the variable name. There's also a PHP defined array named $GLOBALS that uses the name of the globally defined variable as the accessor(e.g., $GLOBALS['varName'])

I love all of your videos so far. I think that this video is treading dangerous territory. I'm sure you go over this later on(confirmed that he does), but I believe this video should have directly addressed what variable scope is. The explanation of functions was uncharacteristically unorganized from what I've seen of your tutorials. I believe you should have explained functions that don't take arguments. Then explained functions that do take arguments. Then explained that functions can return values as well.

I know when teaching about programming, sometimes it's best to just say "we'll explain why later". In this case, I think the order in which things are discussed could easily be confusing.

Specifically the section about scope that talks about local and global scope and how to access a global variable from within a function.

Specifically the sections: Creating PHP Function, PHP Functions with Parameters, Passing Arguments by Reference, and PHP Functions returning value.

It may seem like it's a lot of material, but It's all straightforward and are consistent properties of most programming languages, which is why even though I'm learning php like you, I understand those concepts. I don't think it will take much time at all to absorb what you need to know.

Good tutorials man :) I just have to clarify that the function is not looking for $x. You can call a variable inside the parameters any way you want(like $y). What matters is what you pass trough to that function when you are calling it in newCalc(&x). We are passing value 100 that is contained inside $x and function takes it and saves it into $y.

I have a question in minute 6:37, is that a meowing language?

[vojka]

I just wanna thank you for these awesome tutorials and also thank you for replying my question. I couln't be enjoying this more than I am right now :)

[purnarai]

Thanks sir for such a great teaching. I hope I can study php completely through this chanel.

[aderickzaki]

thank you dan👋 am enjoying your tutorials

[huckleberrymack]

Thank you for these videos, they are absolutely wonderful to compliment my college coursework!!

So to sum up:

Parameters in the functions is like bridges between external code (outside of the function) and inside code (between { }).
Everything I wont to pass from function our in function need to go through parameters?

[pratikthorat]

just a doubt: why not use the break inside the function itself. i mean the line where you've written
echo "This is 75% of what you've written".$newnr. "<br>". That way you can actually avoid writting echo "<br>" all the time

[riaznapa]

Thanks for the video, for a beginner like me it is really easy to understand.

[voiceluckan]

Hi Dani, great content. One question, how do I create an open variable, where the user is the one that inputs the value so that the answer will vary accordingly??

[galynag-eivv]

[jasurjonmamatkulov]

Hi Daniel, Thank You for videos. Could You tell me your Sublime Theme name ? or Was it only
an old version?

[greenmansession]

I dont have the funds to donate on patreon, but I really appreciate the free learning you offer- you're a fantastic teacher so i white-listed your YouTube account on adblock just to give you that little ad revenue. Thanks Daniel.

[mixalisiakovou]
