I'm not sure if there is a function to split a string into an array by characters. I made an example one for you.
PHP Code:
function onCreated()
{
this.string = "Splitting a string by characters";
temp.array = splitstring(this.string);
echo(temp.array);
}
function splitstring(string)
{
for (t=0; t < string.length(); t++)
{
if (string.substring(t,1) != " ")
{
temp.array.add(string.substring(t,1));
}
}
return temp.array;
}
Echo'd 'S,p,l,i,t,t,i,n,g,a,s,t,r,i,n,g,b,y,c,h,a,r,a,c,t ,e,r,s'. I didn't add spaces by default but you can change that if need be. Hope this helps.
