This function simply returns an indexed array in which each element is the corresponding element from array . The returned array is consecutively indexed starting from 0; all keys from the original array are ignored.
One use for this function is to quickly collapse an array that has had some elements unset using unset() into a freshly-ordered indexed array with no blank entries.
$array = array(1, 2, 3, 5, 7, 11, 13, 17, 19, 23); unset($array); unset($array); echo "Original array:\n"; print_r($array); $arr2 = array_values($array); echo "New array:\n"; print_r($arr2); Output: Original array: Array (  => 1  => 2  => 3  => 7  => 11  => 13  => 19  => 23 ) New array: Array (  => 1  => 2  => 3  => 7  => 11  => 13  => 19  => 23 )
