What do you mean by reset the size?
PHP Code:
function onCreated()
{
this.array = {1,2,3};
this.array[0].var = "test";
echo(this.array[0].var);
this.array.add(4);
this.array.add(5);
this.array.remove(4);
echo(this.array);
echo(this.array[0].var);
}
echos
PHP Code:
test
1,2,3,5
test
If the array will be unsorted, give your var a special tag. Thus when you want to update it, just go through the array in a loop until you hit the tag.
