Change an associative array into an indexed array / get an Zend_Table_Row_Abstract as non-associative

Is pure php ok?

$array = array_values($array);

Source

define function

function array_default_key($array) {
    $arrayTemp = array();
    $i = 0;
    foreach ($array as $key => $val) {
        $arrayTemp[$i] = $val;
        $i++;
    }
    return $arrayTemp;
}

Pass the associative array as a parameter and it will convert into the default index of the array. For example: we have Array('2014-04-30'=>43,'2014-04-29'=>41) after the call to the function the array will be Array(0=>43,1=>41).
