This should emulate range() a little better.

<?php

function range_wroar($low, $high, $step = 1) {

    $arr = array();

    $step = (abs($step)>0)?abs($step):1;

    $sign = ($low<=$high)?1:-1;

    if(is_numeric($low) && is_numeric($high)) {

        //numeric sequence

        for ($i = (float)$low; $i*$sign <= $high*$sign; $i += $step*$sign)

            $arr[] = $i;

    }    else    {

        //character sequence

        if (is_numeric($low)) 

            return $this->range($low, 0, $step);

        if (is_numeric($high))

            return $this->range(0, $high, $step);

        $low = ord($low);

        $high = ord($high);

        for ($i = $low; $i*$sign <= $high*$sign; $i += $step*$sign) {

                

            $arr[] = chr($i);

        }

    }

    return $arr;

}

?>
