PHP Integer Data type - Full PHP 8 Tutorial

[@othmannl]

It took me hours to understand the hexadecimal numbers and letters, thanks!

[@ProgramWithGio]

Probably took me the same when I first learned it :)

[@cristianvulpe1408]

Learning something new every single video. I finally realize how much I still need to cover for my ZEND certification. Thank you Gio.

[@ProgramWithGio]

Glad you find these tutorials helpful. You're welcome 🙌

@@ProgramWithGio Should I study PHP 7. First or go straight to PHP 8. .I am a beginner and I don’t know which version of PHP I should study

[@ProgramWithGio]

@@hiennguyen-lw6eu This course starts with 7.4 and goes up to 8.2 so we cover everything that you need.

WOW! I didn't know there was some deep knowledge I was lacking. Thanks :D

Man after not being in university for over 8 years, and been in an information system and project management & service desk role, I completely forgot that binary goes from right to left. So b110 is different to b11, because adding in that final 0 adds the negation of a 1. Each time you add a or a 0, it's defaulting it back to 1, and increasing the left values. Blew my mind whilst having a flash back to in class of looking at a graph from to left on a max value of a byte - already a weird sentence. You're a gem. Thanks for reinvigorating my mind and providing decent stimulation. You speed through this stuff like a breeze and it's super digestible to pause, and try. Good work, you deserve more subs!

[@ProgramWithGio]

Happy to hear, thank you 🙌

[@marombeltran7059]

Everything becomes clearer as I go, thank you infinitely Gio.

[@rustlejack9542]

All understood except hexadecimal,octol and boolean integers.. plzz make another video on that topic

[@ProgramWithGio]

Thank you for the suggestion.

[@osamaibrahim8172]

thank you so much i use to learn new things in php did not know before

[@ProgramWithGio]

Glad to hear that 🙏

[@alexandershnaidman8188]

Great lesson , I've learned a lot

[@ProgramWithGio]

Glad to hear it

[@RaulZham]

My jaw drops since I really don't understand anything about those numbers except decimals. I have learned it before in university but it was long ago. I really forget everything. I think i gonna stop worrying about it and move on until it is really in such dire need of use. Then I will search for that topic specifically.

[@ProgramWithGio]

Don't worry about every little detail, you can always come back to the specific topic like you said. Get to the exercise part & whatever troubles you have go to those topics & watch them again

[@ProgramWithGio]

Thank you

[@veyspixelboy]

Thank you so much for the video, on the part 2:12 when I cast into integer and I var dumb is it still a float and not integer

[@ProgramWithGio]

Yes because maximum integer value is reached so when you add one to it, it turns into float to be able to hold such a large number

[@gazianis7572]

$a = 200_200_2000; echo int($a); that,s great ptc

[@ProgramWithGio]

😏😏

[@dohorishorts]

$x = (int) 'sjsh88' ; prints out int(0); why it behaves like that. It only works if string is followed by number. Any reason why it wont work if string preceeds the number.

[@ProgramWithGio]

Because when it starts with a number its considered a numeric string & can be represented as an int or float. You can check www.php.net/manual/en/language.types.numeric-strings.php for more info

Why I can't see the text in the video?

[@ProgramWithGio]

What do you mean?

[@zouhairsahtout9682]

What I don't like is about this tutorial is you are give too much stuff that are not need it at all, yeah it's good to know that, but not for someone beginner, and you going through the lesson too fast, which my mind kinda fleshed, at half of the video, This tutorial seems good for someone advanced, who just need to fresh his mind not for someone just started because he will end up hating php So I hilly recommend for someone beginner should start with Traversy Media, he's going with you step by step until you build your small project

[@ProgramWithGio]

Thanks for the feedback but I respectfully disagree. I do agree I go a bit faster in beginning videos which I improved on later, note that this is my first attempt at teaching so I'm constantly improving the delivery method. What I don't agree with is that things I teach isn't just "extra". It's important stuff that usually get skipped in crash courses. So if you want to learn basics of PHP in 3 hours sure go for the crash course. If you want to learn more in depth then this is the right one. Many beginners have taken this course and have done pretty well. Even complete beginners, so if you are a beginner give it a shot, don't just dismiss this series based on one feedback. Either way, if anyone ever has any questions/concerns I'm always available and one DM away on Twitter. I also reply to all comments that I get notified about. Cheers 👍

​@@ProgramWithGio nothing to worry, you’re doing great 🌟

[@mrtruth84]

Despite PHP is very ease learning, it has strange behaviors.

[@ProgramWithGio]

Sometimes yes, but PHP is heading in the right direction to remove and minimize such strange behaviors.

how to find the true value before Integer Overflow on a 64-bit system in php

[@ProgramWithGio]

You can use PHP_INT_MAX to find the max int number on machine

[@sofianmezai9051]

this is my code function get ($l,$c){ $value=0; if($c

[@ProgramWithGio]

@@sofianmezai9051 Yea it returns that on my machine (I'm on 64 bit). If you are not getting that value try turning integer to float datatype, it should be able to store bigger number. You can also use as I said PHP_INT_MAX to check if you have reached the maximum & handle it in a different way. What is the problem that you are having?

[@sofianmezai9051]

@@ProgramWithGio i must return this value 14226520737620288370 but i have this value float(1.4226520737620287E+19)

[@ProgramWithGio]

@@sofianmezai9051 that's the same value. It's just in scientific notation. Try using number_format or sprintf to format it the way you want
