How to convert word to number using my function? - php

Question

I created this function to converting numbers to words. And how I can convert words to number using this my function:
Simple function code:
$array = array("1"=>"ЯК","2"=>"ДУ","3"=>"СЕ","4"=>"ЧОР","5"=>"ПАНҶ","6"=>"ШАШ","7"=>"ҲАФТ","8"=>"ХАШТ","9"=>"НӮҲ","0"=>"НОЛ","10"=>"ДАҲ","20"=>"БИСТ","30"=>"СИ","40"=>"ЧИЛ","50"=>"ПАНҶОҲ","60"=>"ШАСТ","70"=>"ҲАФТОД","80"=>"ХАШТОД","90"=>"НАВАД","100"=>"САД");
$n = "98"; // Input number to converting
if($n < 10 && $n > -1){
echo $array[$n];
}
if($n == 10 OR $n == 20 OR $n == 30 OR $n == 40 OR $n == 50 OR $n == 60 OR $n == 70 OR $n == 80 OR $n == 90 OR $n == 100){
echo $array[$n];
}
if(mb_strlen($n) == 2 && $n[1] != 0)
{
$d = $n[0]."0";
echo "$array[$d]У ".$array[$n[1]];
}
My function so far converts the number to one hundred. How can I now convert text to a number using the answer of my function?

Answer 1

So, as #WillParky93 assumed, your input has spaces between words.
<?php
mb_internal_encoding("UTF-8");//For testing purposes
$array = array("1"=>"ЯК","2"=>"ДУ","3"=>"СЕ","4"=>"ЧОР","5"=>"ПАНҶ","6"=>"ШАШ","7"=>"ҲАФТ","8"=>"ХАШТ","9"=>"НӮҲ","0"=>"НОЛ","10"=>"ДАҲ","20"=>"БИСТ","30"=>"СИ","40"=>"ЧИЛ","50"=>"ПАНҶОҲ","60"=>"ШАСТ","70"=>"ҲАФТОД","80"=>"ХАШТОД","90"=>"НАВАД","100"=>"САД");
$postfixes = array("3" => "ВУ");
$n = "98"; // Input number to converting
$res = "";
//I also optimized your conversion of numbers to words
if($n > 0 && ($n < 10 || $n%10 == 0))
{
$res = $array[$n];
}
if($n > 10 && $n < 100 && $n%10 != 0)
{
$d = intval(($n/10));
$sd = $n%10;
$ending = isset($postfixes[$d]) ? $postfixes[$d] : "У";
$res = ($array[$d * 10]).$ending." ".$array[$sd];
}
echo $res;
echo "\n<br/>";
$splitted = explode(" ", $res);
//According to your example, you use only numerals that less than 100
//So, to simplify your task(btw, according to Google, the language is tajik
//and I don't know the rules of building numerals in this language)
if(sizeof($splitted) == 1) {
echo array_search($splitted[0], $array);
}
else if(sizeof($splitted) == 2) {
$first = $splitted[0];
$first_length = mb_strlen($first);
if(mb_substr($first, $first_length - 2) == "ВУ")
{
$first = mb_substr($first, 0, $first_length - 2);
}
else
{
$first = mb_substr($splitted[0], 0, $first_length - 1);
}
$second = $splitted[1];
echo (array_search($first, $array) + array_search($second, $array));
}

You didn't specify the input specs but I took the assumption you want it with a space between the words.
//get our input=>"522"
$input = "ПАНҶ САД БИСТ ДУ";
//split it up
$split = explode(" ", $input);
//start out output
$c = 0;
//set history
$history = "";
//loop the words
foreach($split as &$s){
$res = search($s);
//If number is 9 or less, we are going to check if it's with a number
//bigger than or equal to 100, if it is. We multiply them together
//else, we just add them.
if((($res = search($s)) <=9) ){
//get the next number in the array
$next = next($split);
//if the number is >100. set $nextres
if( ($nextres = search($next)) >= 100){
//I.E. $c = 5 * 100 = 500
$c = $nextres * $res;
//set the history so we skip over it next run
$history = $next;
}else{
//Single digit on its own
$c += $res;
}
}elseif($s != $history){
$c += $res;
}
}
//output the result
echo $c;
function search($s){
global $array;
if(!$res = array_search($s, $array)){
//grab the string length
$max = strlen($s);
//remove one character at a time until we find a match
for($i=0;$i<$max; $i++ ){
if($res = array_search(mb_substr($s, 0, -$i),$array)){
//stop the loop
$i = $max;
}
}
}
return $res;
}
Output is 522.
