Here is a class I started to do that kind of transform
class num_to_text {
var $mode; //NUMERIC CURRENCY
var $words = array(
0=>array('zero','one','two','three','four','five','six','seven','eight','nine','ten','eleven','twelve','thirteen','fourteen','fifteen','sixteen','seventeen','eighteen','nineteen','twenty'),
1=>array('zero','one','twenty','thirty','fourty','fifty','sixty','seventy','eighty','ninety'),
2=>array('thousand','million')
);
var $money = array(
0=>array('Dollar','Dollars'),
1=>array('Cent','Cents')
);
function num_class($mode = 'NUMERIC'){
$this->mode = $mode;
}
function convert($num){
return $this->num($num,1);
}
function num($num,$key = 0){
static $t;
static $call;
$res = intval($num/100);
$left = $num%100;
if($key == 1){ //first non recursive call reset text and
thousand/million toggle
$t = "";
$call = 0;
}
else{
// do we need to print thousand as this is a recursive call
if($num%1000 > 0)$t = ' '.$this->words[2][$call].' '.$t;
$call ^= 1; //toggle call for next recursion
}
if($left <= 20){ // no need to split it
if($left == 0){ // is the whole mess just zero
if($res == 0) $t = $this->words[0][$left].$t;
}
else{
$t = $this->words[0][$left].$t;
}
}
else{ //need to split it up
$tens = intval($left/10);
$units = $left%10;
($units > 0)? $units = ' '.$this->words[0][$units] : $units =
''; //eg thirty or thirty one
$t = $this->words[1][$tens].$units.$t;
}
if($res < 10){
if($res > 0){
($left == 0)? $and = '':$and = ' and '; // do we need
to print 'and'
if($res > 0) $t = $this->words[0][$res]. "
hundred".$and.$t;
}
}
else{
$res = $res%10;
if($res > 0){
($left == 0)? $and = '':$and = ' and ';
$t = $this->words[0][$res]. " hundred".$and.$t;
}
else{
if($left > 0)$t = ' and '.$t;
}
$num = intval($num/1000);
$this->num($num);
}
return $t;
}
}
//usage
$n2t = new num_to_text();
for($num = 0;$num < 11;$num++){
echo $num.' '.$n2t->convert($num).'<br>';
}
