I think you'll need your own function for this.

Nope. Just use array_search(). $k = array_search('5',$Campaign_array); if ($k + 1 > count($Campaign_array)) { echo $Campaign_array[$k + 1]; }

I tried this and it gives me nothing back. It should give me a 8 $Campaign_array= array('0','1','3','5','8','15','25'); $val="5"; $k = array_search($val,$Campaign_array); if ($k + 1 > count($Campaign_array)) { echo $Campaign_array[$k + 1]; }

I figured out way it was not working $k + 1 > count needed to be $k + 1 < count

Yup. Sorry 'bout that.

But now it works perfect

if ($k + 1 > count($Campaign_array)) { echo $Campaign_array[$k + 1]; } is very over-the-top. What's wrong with if (isset($Campaign_array[$k+1]) { echo $Campaign_array[$k + 1]; } Not to mention I don't really like the whole way this has been handled, I'm sure there are better ways, but for this we'd need to know more about what you're doing and what you're trying to achieve, which we obviously don't. - Tul
