PHP Tutorial (& MySQL) #13 - Functions

Показать описание

Hey gang, in this PHP tutorial I want to introduce you to the concept of functions. Functions are an important part of pretty much every programming language, and allow us to create callable blocks of code that can be re-used.

Hello Mr.Ninja,
I am an old student, I watched +35 playlists on your channel for 2 years (I'm now 16 :P), and I worked on myself with that knowledge.
So I wanted to thank you very much for that, words can't even describe it. :)
Keep Going Forward Our Master!

PS: I hope there'll be Laravel playlist and Electron.js too as soon as you can, Best Wishes!

Amazing. In previous tutorial I also learned {} to use in echo. That was something I did not know why my command was not working.

At 8:00 if you decided to concatenate the variables would this be correct?

echo "{$product['name']}" . " costs £ {$product['price']}" . " to buy <br />";

What is the schudule for these videos, because one day you post 1 video, the next 2 and some days nothing. I think i will come back to these videos in a month or so.

So, I've been (slowly) going through this, learning PHP, and so far it's been a really good tutorial. However, as an American, I went to use the dollar sign instead of the pound sign on my cost. It took me several minutes to figure out why my code was breaking - despite the fact that the $ was outside of the command (echo "{$product['name']} costs ${$product['price']} to buy <br />";), PHP didn't like it. I had to change the costs $ to costs L. This seems like an issue in countries that use the dollar sign.

Many thanks but it seems my PHP function code does not work when it is called
formatProduct(['name' => 'pancake', 'price' => 3]); like this and
the error shows Parse error: syntax error, unexpected '[', expecting ')' in necessary to show behind I think)
I am using WampServer so is it because of my server?

At 5:05, I got the output as "Goodmorning $name" instead of "Goodmorning mario".
The code should be something like this: function sayHello($name) { echo 'Goodmorning ' . $name; }
instead of, function sayHello($name) { echo 'Goodmorning $name' ; }

Am I the only one who echoed "say hello to my little friend!!!"; // ? 😛
