[SOLVED] PHP each, next, prev, etc...

I'm trying to re-program a class that someone wrote that has to work with legacy drivers that use while() loops to iterate. I can't seem to get the last element to return any data after it temporarily goes off of the end of the array.

I ended up making an iterator function that looks like this:



Then to gather the current element so I can use the data in any function within the loop, I wrote a function like this:


And during each iteration current_fruit() can be called multiple times. It works, until the set of fruits, I don't get any data. Now the problem is, the loop properly makes enough iterations, but the last element has no data. I realize the each() function sends the pointer temporarily off the end of the array on the last iteration, but prev() should re-point it to the last element, right?

I ended up using end() if prev() returned false. I guess if it goes off the array, you cannot use prev(), you have to reset the entire array to the end() element.

There's a joke about fruits going off the deep end in there somewhere.

Have you ever used the SPL Iterator classes ?

Aww crap I wish I had checked my e-mail, I could have used this. I was using multi-dimensional type array iteration and I ended up having to save it to a datatype, I wouldn't of had to with this.

Thanks man, this will be useful in the future.
