Problem calling method inside same method in php?
- by Fero
Hi all,
Will any one please tell me how to run this class. I am getting the FATAL ERROR: Fatal error: Call to undefined function readnumber() in E:\Program Files\xampp\htdocs\numberToWords\numberToWords.php on line 20 while giving input as 120
<?php
class Test
{
function readnumber($num, $depth)
{
$num = (int)$num;
$retval ="";
if ($num < 0) // if it's any other negative, just flip it and call again
return "negative " + readnumber(-$num, 0);
if ($num > 99) // 100 and above
{
if ($num > 999) // 1000 and higher
$retval .= readnumber($num/1000, $depth+3);
$num %= 1000; // now we just need the last three digits
if ($num > 99) // as long as the first digit is not zero
$retval .= readnumber($num/100, 2)." hundred\n";
$retval .=readnumber($num%100, 1); // our last two digits
}
