Re: Q: while loop on an array

Usually, you would want to use a count variable in your while loop, or to simplify things, you could use a for loop... Example: $arr = array(1, 2, 7, 9, 3); $arr_size = count($arr); for($i = 0; $i < $arr_size; $i++){ /* body of loop here */ $j = $arr[$i]; } this starts off with $i = 0, and increments it at the end of each loop. As soon as $i is incremented past the last element in the array, the check $i < $arr_size will come up false, and so the loop will not be entered any more. You can do the same thing in a while loop by intializing a variable to 0 before the loop, and have a statment in the body of the loop that increments it each time... Hope that helps.
