Hi, setup your array starting with the highest values: $array = array(200, 200, 100, 50, 30); Then use array_count_values($array). This will give you an associative array where the key is the former value and the value is the number of the occurrences. In your case this would be: array(200 => 2, 100 => 1, 50 => 1, 30 => 1); Then loop through the array with foreach() and check each element for the value 1. When you have found the first array element with a value of 1 exit from the loop with break. Hope this works for you.
