Usage

Usage is simple. If we called a class: Class_brojuslova.php, code for creating an object can be as followed:

<?php
    require_once 'Class_brojuslova.php';
    $a = 500;
    
    $obj = new Class_brojuslova.php();
    $number_letters = $obj->upravljac($a);
    
    echo number_letters; // print: petstokuna
?>

If you use a framework, example for CodeIgniter within some controller method would be as following (the class would live in a library section):

<?php

    // initialization of class class_brojuslova from a library
    $this->load->library('class_brojuslova');
    $brojzaslova = "500.35";

    // conversion of number in a letter
    $data['sumslovima'] = $this->class_brojuslova->upravljac($brojzaslova);

?>
