Hello Reader's! If you have given digits of number and you want it to convert into words for example 76 will be converted as seventy six and 102 will be convert as one hundred two

Lets see the function below:-

<?php
    function digittiwords($number){
        $words = array(
        '0'=> '' ,'1'=> 'one' ,'2'=> 'two' ,'3' => 'three','4' => 'four','5' => 'five',
        '6' => 'six','7' => 'seven','8' => 'eight','9' => 'nine','10' => 'ten',
        '11' => 'eleven','12' => 'twelve','13' => 'thirteen','14' => 'fouteen','15' => 'fifteen',
        '16' => 'sixteen','17' => 'seventeen','18' => 'eighteen','19' => 'nineteen','20' => 'twenty',
        '30' => 'thirty','40' => 'fourty','50' => 'fifty','60' => 'sixty','70' => 'seventy',
        '80' => 'eighty','90' => 'ninty');

        //First find the length of the number
        $number_length = strlen($number);
        //Initialize an empty array
        $number_array = array(0,0,0,0,0,0,0,0,0);        
        $received_number_array = array();

        //Store all received numbers into an array
        for($i=0;$i<$number_length;$i++){    $received_number_array[$i] = substr($number,$i,1);    }

        //Populate the empty array with the numbers received - most critical operation
        for($i=9-$number_length,$j=0;$i<9;$i++,$j++){ $number_array[$i] = $received_number_array[$j]; }
        $number_to_words_string = "";        
        //Finding out whether it is teen ? and then multiplying by 10, example 17 is seventeen, so if 1 is preceeded with 7 multiply 1 by 10 and add 7 to it.
        for($i=0,$j=1;$i<9;$i++,$j++){
            if($i==0 || $i==2 || $i==4 || $i==7){
                if($number_array[$i]=="1"){
                    $number_array[$j] = 10+$number_array[$j];
                    $number_array[$i] = 0;
                }        
            }
        }

        $value = "";
        for($i=0;$i<9;$i++){
            if($i==0 || $i==2 || $i==4 || $i==7){    $value = $number_array[$i]*10; }
            else{ $value = $number_array[$i];    }            
            if($value!=0){ $number_to_words_string.= $words["$value"]." "; }
            if($i==1 && $value!=0){    $number_to_words_string.= "Crores "; }
            if($i==3 && $value!=0){    $number_to_words_string.= "Lakhs ";    }
            if($i==5 && $value!=0){    $number_to_words_string.= "Thousand "; }
            if($i==6 && $value!=0){    $number_to_words_string.= "Hundred &amp; "; }
        }
        if($number_length>9){ $number_to_words_string = "Sorry This does not support more than 99 Crores"; }
        return ucwords(strtolower("Indian Rupees ".$number_to_words_string)." Only.");
    }

        ?>

<php 
echo digittowords("987654321");
?>

Output will be:-

Indian Rupees Ninty Eight Crores Seventy Six Lakhs Fifty Four Thousand Three Hundred & Twenty One
