Video created 7 years ago. still valid today... much better than paid courses!! Thanks a lot Derek :)

@prabhjotNZ The . is the concatenation operator in PHP use it for putting 2 strings together. The comma can be used for multiple types

[derekbanas]

I use double quotes out of habit because when using single quotes any variables inside aren't evaluated to their value. I heard a long time ago that it was quicker to use commas with echo, so that is why I do that. I know you can't use them with print.

You'll pick up habits over time. I'm glad you liked the video :)

you should make audio books your voice is just amazing,

[derekbanas]

@powerhousephg Yes you are correct. In tutorials I don't always make everything as efficient as possible. Most of the time I'm doing this stuff out of my head and make little errors like that

[derekbanas]

Thank you :) I have weird allergies that make my voice go crazy. I'm glad you like it

[derekbanas]

Dziękuję. Jestem szczęśliwy, że pomoże im :)

Because my english is not so brilliant as yours tutorials I'm gonna write a comment in my language:
Niesamowite tutoriale- szybko, konkretnie i bardzo przejrzyście nawet jak jak na takiego laika w sprawach PHP jak ja.
What in shortcut means AWESOME !!!

foreach makes it easy to iterate over arrays, or objects. If you have foreach (your_array as $value) your_array is the array you will be iterating through from start to finish. Each step of the way the current value stored in array is assigned to $value. Does that help?

[derekbanas]

@rupamguha Not sure what you mean by exchange keys and values?

[derekbanas]

@dreamtownuk I sent your answer in another post. i hope that helps

[darkandgreen]

@derekbanas Can you explain more please? Can they both not do the same thing? . and, are doing the same thing for me

[lupitchr]

Can you please explain the "as" statement in a bit more detail in the for each loop. Not sure why, but it's confusing me. I just want to know what the code is telling the computer to do when it runs foreach ( $customers as $keys). Thanks!

[sethu]

Also please explain the use of print_r method

[thespeakerstaffinformation]

You should explain why we would use this and what the functions are pointing to first. It was difficult to follow the list of commands you provided without the foundation of potential use.

[darkandgreen]

Thanks!

Questions:
in the array, we are using double quotes, array("Name" => "Mike), in the $_POST['We use single'], So, why cant we use single quotes in arrays? or why cant we use double in $_POST, I'm very confused on when to use double or single

Question 2

You are sometimes using
echo $Var1, " ", $var2;

other times you are using
echo $var1 . " " . $var2;
they both do the same thing? as the results are identical
When do we use each?

Thanks 100 times

What font do you use in your coding program?

[bobcabatbat]

is it possible to just call on the value of the $myinfo?
usually i do is
$example = array("ex1", "ex2", )
echo $example[1];

OUTPUT:
ex2

but since you put a value on the key, is it possible to just print the value in it?

Hey, I would love to see how to make a website with a database (for example to make a webshop or intranet for companies) and how to use CMS so people can edit their own text-content without changing my design.
