Answer 1

bellow I am giving you an example function. It may not be a complete one but it should get you started (I know, the question has been posted long ago. still, it may help others - ) And I am sorry for any bugs :). and lastly, it is not finished one. I just post for an example starting point.

function convertToString($number, $blankIfZero=true){
        $strRep = "";
        $n = intval($number);       
        $one2twenty = array("One", "Two", "Three", "Four", 
                "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Eleven",
                "Twelve", "Thirteen", "Fourteen", "Fifteen", "Sixteen",
                "Seventeen", "Eighteen", "Nineteen");
        $twenty2ninty = array("Twenty", "Thirty",
                "Fourty", "Fifty", "Sixty", "Seventy", "Eighty",
                "Ninety");
        $hundred = "Hundred";
        $thousand = "Thousand";
        $million = "Million";
        $billion = "Billion";

        switch($n){
            case 0: 
                if($blankIfZero == true){
                    $strRep= $strRep."";
                    break;
                }else{
                    $strRep = $strRep."Zero";
                    break;
                }
            case $n >0 && $n <20:
                $strRep = $strRep." ".$one2twenty[($n-1)];              
                break;
            case $n >=20 && $n < 100:               
                $strRep = $strRep . " ". $twenty2ninty[(($n/10) - 2)];
                $strRep .= convertToString($n%10);
                break;
            case $n >= 100 && $n <= 999:
                $strRep = $strRep.$one2twenty[(($n/100)-1)]." ".$hundred. " ";
                $strRep .= convertToString($n%100);
                break;
            case $n >= 1000 && $n < 100000:
                if($n < 20000){
                    $strRep = $strRep.$one2twenty[(($n/1000)-1)]." ".$thousand. " ";
                    $strRep .= convertToString($n%1000);
                    break;
                }else{
                    $strRep = $strRep . $twenty2ninty[(($n/10000) - 2)];
                    $strRep .= convertToString($n%10000);
                    break;
                }
            case $n >= 100000 && $n < 1000000:
                $strRep .= convertToString($n/1000). " ".$thousand. " ";
                $strRep .= convertToString(($n%100000)%1000);
                break;
            case $n >= 1000000 && $n <  10000000:                   
                $strRep = $strRep . $one2twenty[(($n/1000000) - 1)]. " ".$million." ";
                $strRep .= convertToString($n%1000000);
                    break;
            case $n >= 10000000 && $n < 10000000000:
                $strRep .= convertToString($n/1000000). " ".$million. " ";
                $strRep .= convertToString(($n%1000000));
                break;

        }

        return $strRep;
    }
