3 Dimensional Array

ReSpawN · 12-30-2007, 07:18 PM

Hey guys,

I've been trying to figure out something for quite some time now. Decided to give it a try.

PHP Code:


			
    $result = query('SELECT * FROM user_data WHERE user_id = "2"');

    $b03tz = mysql_fetch_array($result);



    $result2 = query('SELECT * FROM user_data WHERE user_id = "3"');

    $respawn = mysql_fetch_array($result2);

    

    $globals = array();

    foreach ($respawn as $key => $value) {

        array_push($globals, $respawn2[$key]);

    }

    foreach ($b03tz as $key => $value) {

        array_push($globals, $b03tz[$key]);

    }

In plain man terms, it's shows a list with some data.

What do I want to do?
We have 2 arrays in an array. The one exports ReSpawN's stats, and the other exports b03tz's. In $global, I've pushed $respawn row results and $b03tz row results.

Now the question is, how do I make them show up in a list like so:
echo $global[$respawn[1]]; or something like that. It's completely new to me so I haven't got a clue what to do.

I also want to GENERATE the difference. When my level of, lets say, a building, is higher than that of b03tz, it shows the difference. For example:

ReSpawN 1
b03tz 0
Difference 1
Mine of course, is green, and b03tz's is red.

Can one of you guys help me out here?

Hi Mark,

I'm afraid I don't fully understand what you are trying to do, but I've taken a guess based on your thread title :D

At the moment, your current code would make your $globals array look something like this:

PHP Code:


			
/*

Array

(

    [0] => respawn_value1

    [1] => respawn_value2

    [2] => respawn_value3

    [3] => b03tz_value1

    [4] => b03tz_value2

    [5] => b03tz_value3

)

*/

Which I'm guessing is not what you where after. I've made some adjustments to the code to put your 2 arrays into a 3 dimensional array:

PHP Code:


			
$b03tz = array('b03tz1' => 'b03tz_value1',

               'b03tz2' => 'b03tz_value2',

               'b03tz3' => 'b03tz_value3');



$respawn = array('respawn1' => 'respawn_value1',

               'respawn2' => 'respawn_value2',

               'respawn3' => 'respawn_value3');    



           

$globals = array(); 



foreach ($b03tz as $key => $value)

{

    $globals['b03tz'][$key] = $value;

}



foreach ($respawn as $key => $value)

{

    $globals['respawn'][$key] = $value;

}

This new code makes your $globals array look like this:

PHP Code:


			
/*

Array

(

    [b03tz] => Array

        (

            [b03tz1] => b03tz_value1

            [b03tz2] => b03tz_value2

            [b03tz3] => b03tz_value3

        )



    [respawn] => Array

        (

            [respawn1] => respawn_value1

            [respawn2] => respawn_value2

            [respawn3] => respawn_value3

        )



)

*/

Is this the sort of array that you where trying to achieve?

To access the values in this array you would use something like:

PHP Code:


			
echo $globals['respawn']['respawn2'];



// This would echo "respawn_value2" if using the above arrays

As for the comparison question, if you could give some examples of the data in the arrays I can probably knock some examples up for you.

Then again ^ thats just a two dimentional array. To be honest only reason I could see a 3 dimentional array being used is because you are doing something with levels and maps ie:

$game['level_1']['map1']['map_peice1'] = 1;
$game['level_1']['map1']['map_peice2'] = 1;

So maybe 3 dimentional arrays are not what he means possibly what you said is what hes looking for :).
