# Löjligt enkelt? Omvandla siffror...

## #1 — Pontus Thor, 2003-07-05T12:03Z

Hittade precis den funktionen jag behövde men upptäkte att jag inte vet hur man använder den...  :e 

```php
                <?php

  function roman($num) {
    $chars = array("I", "V", "X", "L", "C", "D", "M");
    $str = strval($num);

    $len = strlen($str);
    $result = "";
    for ($i = 0; $i < $len; $i++) {
      $base = 2 * ($len - $i - 1);
      $chs = array($chars[$base], $chars[$base + 1], $chars[$base + 2]);
      $romanchars = array("",
        $chs[0],
        $chs[0] . $chs[0],
        $chs[0] . $chs[0] . $chs[0],
        $chs[0] . $chs[1],
        $chs[1],
        $chs[1] . $chs[0],
        $chs[1] . $chs[0] . $chs[0],
        $chs[1] . $chs[0] . $chs[0] . $chs[0],
        $chs[0] . $chs[2]);

      $result .= $romanchars[$str[$i]];
    }
    return $result;
  }

?>
```

  

mitt bästa försök: 

```php
<?php
$num = 11; // pontus
  function roman($num) {
    $chars = array("I", "V", "X", "L", "C", "D", "M");
    $str = strval($num);

    $len = strlen($str);
    $result = "";
    for ($i = 0; $i < $len; $i++) {
      $base = 2 * ($len - $i - 1);
      $chs = array($chars[$base], $chars[$base + 1], $chars[$base + 2]);
      $romanchars = array("",
        $chs[0],
        $chs[0] . $chs[0],
        $chs[0] . $chs[0] . $chs[0],
        $chs[0] . $chs[1],
        $chs[1],
        $chs[1] . $chs[0],
        $chs[1] . $chs[0] . $chs[0],
        $chs[1] . $chs[0] . $chs[0] . $chs[0],
        $chs[0] . $chs[2]);

      $result .= $romanchars[$str[$i]];
    }
    return $result;
  }
    print("$result");  // pontus
?>
```

Någon?

```php
$num = 11;

echo roman($num); // Skriver ut det romerskanr.

$tmp = roman($num); // $tmp variabeln innehåller nu det romerskanr.
exit;

  function roman($num) {
    $chars = array("I", "V", "X", "L", "C", "D", "M");
    $str = strval($num);

    $len = strlen($str);
    $result = "";
    for ($i = 0; $i < $len; $i++) {
      $base = 2 * ($len - $i - 1);
      $chs = array($chars[$base], $chars[$base + 1], $chars[$base + 2]);
      $romanchars = array("",
        $chs[0],
        $chs[0] . $chs[0],
        $chs[0] . $chs[0] . $chs[0],
        $chs[0] . $chs[1],
        $chs[1],
        $chs[1] . $chs[0],
        $chs[1] . $chs[0] . $chs[0],
        $chs[1] . $chs[0] . $chs[0] . $chs[0],
        $chs[0] . $chs[2]);

      $result .= $romanchars[$str[$i]];
    }
    return $result;
  }
```
