array modifiers

Let's say I have an array:

PHP Code:


		
			
this.fuit={"apple","orange","bananna"};

and you want to add "pear" to the array.
What would it involve to get the array to look like:

PHP Code:


		
			
this.fuit={"apple","orange","bananna","pear"};

PHP Code:


		
			
this.fuit={"pear","apple","orange","bananna"};

PHP Code:


		
			
this.fuit={"apple","orange","pear","bananna"};

?

and what is involved in removing an item from an array of strings and having the array self-compress so there are no emty spaces, such as:
before

PHP Code:


		
			
this.fuit={"apple","orange","bananna"};

and after

PHP Code:


		
			
this.fuit={"apple","bananna"};

PHP Code:


		
			
varname.add("str");

varname.remove("str");

varname.insert(index, "str");

varname.delete(index);

Ajira's right, but that doesn't work for multidimensional arrays (yet?)

Yes it does, array[index].add() etc.

Well, I was having problems with it. This is what I meant about the problem of using the standard object stuff on a specific dimension of an array:

That's just visual... the value has changed.

I've never had problems using array[index].add() and such.

Edit: Ah, didn't see Rick's post, but he is right :p

But visually it can be very important.

...why? Do you normally show raw array contents to people?
