OK, i tried the easiest way of my beginning in FLASH with loadvariables, coz
i'm a beginner..
To avoid headache thinking of a dimensional array, i would prefer to simplify it by using
long code in flash (more code in flash).It is because, coding in FLASH, is quite easier
. But it's worth for beginner

First oFF, we want to have a simple 2 dimensional array

PHP Code:


		
			
 myArray[0][0]="Pakcik"

myArray[0][1]="Kantin"



myArray[1][0]="Makcik"

myArray[1][1]="Sekolah"

Let start with a load action from text file named Text.txt. The text file would have a code like these:
&myDimensionalArray=pakcik:kantin,makcik:sekolah&quit=quit

Then in the FLASH 5.0

1.loadVariablesNum ("Text.txt", 0);(Loaded after frame 1, just to make sure it is loaded, maybe frame 5)
2.The next frame, we try to make it as a 1 dimensional array first, by splitting the comma (,) first

PHP Code:


		
			
 newTwoDArray = myDimensionalArray.split(",");

    newTwoDArrayLength=newTwoDArray.length;

    

    for (var i=0; i<newTwoDArrayLength ; i++) 

    {

        //If you want to view it in a dynamic text simply use this

        //nextText+="This is " add a[i];

        //If you want to view it , use trace

        trace("Array[" add i add "]=" add newTwoDArray[i]);

    }

#This is to check wether the Array is built OK
#If it is working then we can continue
#Output

Array[0]=pakcik:kantin
Array[1]=makcik:sekolah

3. In the same frame (If it is OK to view) , we can start splitting our array into 2 dimensional array

PHP Code:


		
			
for (var i = 0; i<newTwoDArrayLength; i++) 

    {    

        tmpArray = new Array();    

        tmpArray = newTwoDArray[i].split(":");

        tmpArrayLength =     tmpArray.length;

        newTwoDArray[i]= new Array();

    

        for (var j = 0; j<tmpArrayLength; j++) 

        {        

            newTwoDArray[i][j]="Array[" add i add "][" add j add "]=" add tmpArray[j];

            

            //If you want to view it in a dynamic text simply use this

            //nextText+=newTwoDArray[i][j];

            //If you want to view it , use trace

            trace (newTwoDArray[i][j]);

        }

    }

#The purpose of tmpArray is that, we cannot split the newTwoDArray[i] and assigning back to it again

#Output

Array[0]=pakcik:kantin
Array[1]=makcik:sekolah

Array[0][0]=pakcik
Array[0][1]=kantin
Array[1][0]=makcik
Array[1][1]=sekolah

#The first 2 lines is the 1 dimensional array, the rest is the 2 dimesional array

Hope this will help, based on what i understand.
Conclusion of the function

PHP Code:


		
			
 newTwoDArray = myDimensionalArray.split(",");

    newTwoDArrayLength=newTwoDArray.length;

for (var i = 0; i<newTwoDArrayLength; i++) 

    {    

        tmpArray = new Array();    

        tmpArray = newTwoDArray[i].split(":");

        tmpArrayLength =     tmpArray.length;

        newTwoDArray[i]= new Array();

    

        for (var j = 0; j<tmpArrayLength; j++) 

        {        

            newTwoDArray[i][j]="Array[" add i add "][" add j add "]=" add tmpArray[j];

            

            //If you want to view it in a dynamic text simply use this

            //nextText+=newTwoDArray[i][j];

            //If you want to view it , use trace

            trace (newTwoDArray[i][j]);

        }

    }
