hi again jocke... seems i'll give a go at answering your questions again ;-) If I understand your question properly, I doubt the previous poster's response would be useful to you. The bad news (I think): there are limited functions that deal with array pointers. There are plenty to deal with arrays themselves. as you've noted: pos, next, prev seem to be the only way to deal with a pointer, so yes, the way that I implemented my solution was to use next and pos to get the positioning and in doing so, reading the *entire array* (yuck) and storing into a new array based on conditions. option 1) I haven't tried, so I'm not sure if array_search (for key) and in_array (for value) move the pointer - maybe you could try those. (gut feel is they don't). If they do, then you can for loop a prev/next to get what you want. option 2) I guess you could actually use integers as your index and have them sort-ed (or array_push them on) that might solve your problem, but I think that's a bit of a kludge. (ie, implicitly using the array key value as a pointer) option 3) So.... the only way I found was to loop thru the whole array, it's messy for large sets, but if your array size is only 100 (I doubt it is) it may be ok. It seems excessive though. looping thru the entire set might not be too bad, I assume that's what an array_search might be doing as well(?) so you're not saving any more time even if that works. Anyhow, tell me if you find another method... i'll go off and do more research on it now too.
