This is a great channel and you have done a good job so far. I am a college student for programming and next quarter we start using PHP so I wanted to get a few months practice in before then. So far your tutorial has been just as good as my instructor's lectures on the other programming languages we are learning. I look forward to finishing this series, thank you for providing such a great tool for developers in the making!

Multidimensional arrays are super useful especially when using MVC and passing data to Vue components. I can pass a single prop and put all the data and arrays inside of it instead of passing multiple props.

Hey Shaun, just wanted to let you know that there is a channel called "Codex Tron", who just reuploads your videos you should report it and take his videos down.

[shannonstumpf]

i'm loving this series! what is the difference between print r and echo?

[Hejhouyou]

Awesome job. Can't wait to see you explain how superglobals work. Mainly cookies, sessions, post, get etc ...

[hotsmissed]

array_pop function can also delate the last item of array but when we store this function inside the variable it delate the last item in this array and store that delated item inside the variable so it make sense right now we've just echoing this variable by print_r() function

How can we take results from an mysql query (oci) and dump the values to the array..

for example, it my query I have the results of product id, name and price (3 "columns") and it returns 3 records. How can I add each record/row from the query and add them into an array? I think I have to use a loop right? then what array_add or something like that? I think this is called array_push correct? how to loop and add it?

How to create multi dimensional array with array variables

$var = array ( array(
array(1, 2, 3, 4),
array(2, 4, 3, 6),
array (7, 5, 3, 2) ),
array(
array(1, 2, 3, 4),
array(2, 4, 3, 6),
array(8, 5, 4, 3) )
);

I want to create the above array with array variables like below
$a = array(1, 2, 3, 4);
$b = array(2, 4, 3, 6);
$var = array ( array(
$a,
$b,
array (7, 5, 3, 2) ),
array(
array(1, 2, 3, 4),
array(2, 4, 3, 6),
array(8, 5, 4, 3) )
);
But it is giving errors
How to implement this ?
Thanks in advance.

Oooohps, Shaun I have a problem related with your "react redux and firebase series" marioplan; there's a breaking changes to the react redux firebase, can you just adress even with 2 minutes video, if it's not too much to ask. As always keep up the good work.

Is not it better to present examples using xdebug? Visually better.

<?php

$blogs = [
['mario', 'luigi', 'yoshi'],
['peach', 'bowser', 'toad'],
['luigi', 'bowser', 'koopa']
];

$characters = array('mario', 'luigi', 'yoshi',
array('peach', 'bowser', 'toad'),
array('luigi', 'bowser', 'koopa'));

$items[] = ['mario'=>'luigi', 'yoshi'=>'bowser', 'peach'=>'toad'];

echo $blogs[2][1] . '<br>';
echo $characters[4][1] . '<br>';
echo $items[0]['yoshi'] . '<br>';
