|0:00
|A multidimensional array is an array in which you can store other arrays.
|-
|0:06
|It is very similar to an associative array.
|-
|0:09
|However, the associates for this array are arrays themselves.
|-
|0:14
|For a better understanding, let us start the program.
|-
|0:19
|I will create a program that lets you see the position of a letter in the English
alphabet.
|-
|0:26
|For example, if I give the value 1, it should echo out "A" in position 1.
|-
|0:33
|If I give the value two it would say "B" in position 2.
|-
|0:38
|And for three, it will say "C" is in position 3, and so on.
|-
|0:43
|First I will create my own array.
|-
|0:53
|And just for easy viewing, I will bring this down.
|-
|0:58
|You are quite welcome to do so yourself.
|-
|1:01
|And inside. I will create my own array, which I will call ‘ABC’.
|-
|1:10
|That will be the array.
|-
|1:15
|Instead of putting a value here, as we did before, we have an array inside.
|-
|1:24
|And inside these, will be the values, for example, Capital A, B, C and D.
|-
|1:32
|And these values will be separated by commas.
|-
|1:41
|And then we type “123” and that is equal to an array.
|-
|1:46
|Now we’re just going to have ‘1,2,3,4, and that’s it.
|-
|1:53
|Down here, I’ll show you how to echo out specific data inside the array.
|-
|1:59
|We’ll call our main array.
|-
|2:02
|And we’ll call this array as well.
|-
|2:05
|And then the position of what you want inside the array. So it is an array inside an array.
|-
|2:13
|So I will just type ‘echo’ and then ‘alpha’ which is our main array.
|-
|2:19
|And then inside square brackets, ‘ABC’.
|-
|2:23
|And next, inside square brackets, the position of the element if you want to retrieve.
|-
|2:30
|Now, for example, is going to echo "A".
|-
|2:35
|Let us give that a run - and we got "A".
|-
|2:47
|Changing this to ‘123’, will hopefully give us "1".
|-
|2:54
|As you can see here.
|-
|2:57
|So we've made our two basic arrays inside our main arrays, and we’ve learnt to call it.
|-
|3:05
|Now I’m going to create a new program to find out the position of a letter in relation to its number.
|-
|3:13
|I’m going to type up here ‘ postion = 0’, since 0 is the beginning.
|-
|3:30
|Now I will echo out ‘Letter something is in position something’.
|-
|3:39
|This is going to be quite simple.
|-
|3:42
|We enter a position here, say 3. Since C is in position 3 in the alphabet, we get C.
|-
|3:53
|So , to echo out our letter, if I am going to replace the first blank with ‘alpha’.
|-
|4:02
|ABC
|-
|4:05
|'pos'
|-
|4:07
|as 'pos' represents our position.
|-
|4:11
|So then, the position will be - Alpha... 123
|-
|4:19
|And then the position, ‘pos’.
|-
|4:23
|At the moment, position is equal to 0.
|-
|4:29
|We type ’echo something’. So this is position zero.
|-
|4:36
|Position zero inside the internal array “ABC”. So in actual fact, we are saying that A is in position 0,
|-
|4:47
|which is this array, 123 and that is position zero. So actually we are saying letter A is in position one.
|-
|4:56
|Lets run this. Okay. A is in position 1. Let’s change this to 1.
|-
|5:05
|Refresh. Letter B is in position 2. Now what I will do to make this application fully functional and easy to navigate, is eliminate the necessity to write zero for 1.
|-
|5:21
|So I will put ‘-1’ at the end and put 1 in brackets for better legibility.
|-
|5:28
|So, position one minus one is infact zero. So, writing 1 will give the same result as writing 0. Writing 2 will give us the same result as writing 1...letter B is in position 2.
|-
|5:43
|If I put 1 then we get A is in position 1. So if I put zero here; there is no position -1; so we get “letter in position”. So we don’t have the letter or the position.
|-
|6:01 onwards
|So, I’ve made that a bit more user-friendly. Thanks for watching!
