PHP Two Dimensional Array
In the array, we sometimes need to save different properties of the index value. At situations like these, we use two dimensional array. For example : In the checkout application, there may be array elements that we need to add to the index value with product ID, such as product name, price, and quantity. In the software that we talked about before, we mentioned the checkout logic. Now moving on from this topic, I'll do the introduction.
Defining 2 Dimensional Array
We define the single dimensional array like this :
Kod:
[B][COLOR=White][FONT=Microsoft Sans Serif][COLOR=Silver][FONT=Lucida Console][COLOR=Sienna]$dizi_adi[/COLOR] = [COLOR=MediumTurquoise]array[/COLOR]([COLOR=Lime]"eleman1"[/COLOR],[COLOR=lime]"eleman2"[/COLOR],[COLOR=lime]"eleman3"[/COLOR]);
[/FONT][/COLOR][/FONT][/COLOR][/B]
Kod:
[COLOR=White][FONT=Microsoft Sans Serif][COLOR=silver][FONT=Lucida Console] [COLOR=Sienna]<?php[/COLOR] [COLOR=#ff5555]$dizi[/COLOR] = [COLOR=mediumturquoise]array[/COLOR]( [COLOR=MediumTurquoise]array[/COLOR]([COLOR=darkorange]1[/COLOR],[COLOR=darkorange]2[/COLOR],[COLOR=darkorange]3[/COLOR],[COLOR=darkorange]4[/COLOR]), [COLOR=mediumturquoise]array[/COLOR]([COLOR=darkorange]2[/COLOR],[COLOR=darkorange]3[/COLOR],[COLOR=darkorange]4[/COLOR],[COLOR=darkorange]5[/COLOR]), [COLOR=mediumturquoise]array[/COLOR]([COLOR=darkorange]5[/COLOR],[COLOR=darkorange]6[/COLOR],[COLOR=darkorange]7[/COLOR],[COLOR=darkorange]8[/COLOR]), [COLOR=mediumturquoise]array[/COLOR]([COLOR=darkorange]9[/COLOR],[COLOR=darkorange]10[/COLOR],[COLOR=darkorange]11[/COLOR],[COLOR=darkorange]12[/COLOR]), ); echo [COLOR=#ff5555]$dizi[/COLOR][[COLOR=DarkOrange]1[/COLOR]][[COLOR=darkorange]2[/COLOR]]; [COLOR=sienna]?>[/COLOR][/FONT][/COLOR]
[COLOR=silver][FONT=Lucida Console] [/FONT][/COLOR]
[/FONT][/COLOR][COLOR=White][FONT=Microsoft Sans Serif]
[/FONT][/COLOR]The output is 2nd phrase. 3rd column, meaning it's going to be 4
Let's make a checkout application about this.
First of all let's create a session and define it as an array.
Kod:
[FONT=Microsoft Sans Serif][B][COLOR=White][FONT=Microsoft Sans Serif][COLOR=Silver][FONT=Lucida Console] [COLOR=Sienna]<?php[/COLOR] [COLOR=MediumTurquoise]session_start[/COLOR](); [COLOR=#ff5555]$_SESSION[/COLOR][[COLOR=Lime]"sepet"[/COLOR]] = [COLOR=mediumturquoise]array[/COLOR](); [COLOR=sienna]?>[/COLOR][/FONT][/COLOR][/FONT][/COLOR][/B]Now, let's create an index through the product ID and add the datas as if there is an array with 3 elements. We don't need to define this array again. After that, let's take the output with print_r view it. I checked it by assigning the variables myself.
Kod:
[FONT=Microsoft Sans Serif][B][COLOR=White][FONT=Microsoft Sans Serif][FONT=Lucida Console] [COLOR=#ff5555]$_SESSION[/COLOR][[COLOR=lime]"sepet"[/COLOR]][[COLOR=#ff5555]$urun_id[/COLOR]][[COLOR=DarkOrange]0[/COLOR]] = [COLOR=#ff5555]$urun_isim[/COLOR]; [COLOR=#ff5555]$_SESSION[/COLOR][[COLOR=Lime]"sepet"[/COLOR]][[COLOR=#ff5555]$urun_id[/COLOR]][[COLOR=darkorange]1[/COLOR]] = [COLOR=#ff5555]$urun_fiyat[/COLOR]; [COLOR=#ff5555]$_SESSION[/COLOR][[COLOR=lime]"sepet"[/COLOR]][[COLOR=#ff5555]$urun_id[/COLOR]][[COLOR=darkorange]2[/COLOR]] = [COLOR=#ff5555]$urun_adet[/COLOR]; [COLOR=MediumTurquoise]print_r[/COLOR]([COLOR=#ff5555]$_SESSION[/COLOR][[COLOR=Lime]"sepet"[/COLOR]]);[/FONT][/FONT][/COLOR][/B] [URL="https://i.hizliresim.com/4dKDtQ.png"][IMG]https://i.hizliresim.com/4dKDtQ.png[/IMG][/URL][/FONT]
Kod:
[FONT=Microsoft Sans Serif][B][COLOR=White][FONT=Microsoft Sans Serif][FONT=Lucida Console][COLOR=Silver] [COLOR=MediumTurquoise]echo [/COLOR][COLOR=lime]"<pre>"[/COLOR]; [COLOR=mediumturquoise]print_r[/COLOR]([COLOR=#ff5555]$_SESSION[/COLOR][[COLOR=Lime]"sepet"[/COLOR]]); [COLOR=mediumturquoise]echo [/COLOR][COLOR=lime]"</pre>"[/COLOR];[/COLOR][/FONT][/FONT][/COLOR][/B]The output will be like this:
