$city = $fi->getCity('00900'); // Returns "HELSINKI"

// Get full record
$record = $fi->getRecord('00900');
echo $record->postcode_fi_name; // "HELSINKI"
echo $record->municipal_name_fi; // "Helsinki"
echo $record->ad_area_fi; // "Helsinki-Uusimaa"

// Check if postal code exists
if ($fi->exists('00900')) {
    // ...
}

// Get all postal codes
$allPostcodes = $fi->getAllPostcodes();

// Iterate over all records (memory efficient)
foreach ($fi->getFull() as $postcode => $record) {
    // Process each record
}
```

### Direct File Access
