use function Lytrax\AFM\generateValidAFM;
use function Lytrax\AFM\generateInvalidAFM;
```

Validate a number:

```
validateAFM('090000045');

```

Generate an invalid number:

```
generateInvalidAFM();
string(9) "853003357"

API
---

[](#api)

**validateAFM** `($afm, $params = [])`

- `$afm: string` - A number to be checked
- `$params: array (optional)` - Optional associative array for named parameters
- `$params['extendedResult']: boolean = false` - Return a `boolean` or `array`
- **Returns**: `boolean` or `array` (Associative array with `valid: boolean` and `error: string ('length' or 'nan' or 'zero' or 'invalid')`)

Example:

```
validateAFM('ab1234', ['extendedResult' => true]);
array(2) {
  ["valid"]=>
  bool(false)
  ["error"]=>
  string(6) "length"
}
```

**generateAFM** `($params = [])`

- `$params: array (optional)` - Optional associative array for named parameters
- `$params['forceFirstDigit']: null|int (optional)` - If specified, overrides all pre99, legalEntity and individual
- `$params['pre99']: boolean = false` - Για ΑΦΜ πριν από 1/1/1999 (ξεκινάει με 0), (if true, overrides both legalEntity and individual)
- `$params['individual']: boolean = false` - Φυσικά πρόσωπα, (ξεκινάει με 1-4)
- `$params['legalEntity']: boolean = false` - Νομικές οντότητες (ξεκινάει με 7-9)
- `$params['repeatTolerance']: null|int (optional)` - Number for max repeat tolerance (0 for no repeats, unspecified for no check)
- `$params['valid']: boolean = true` - Generate valid or invalid AFM
- **Returns**: `string` - A valid or invalid 9 digit AFM number

Example:

```
generateAFM([
  'forceFirstDigit' => 3,
  'repeatTolerance' => 1,
  'valid' => true
]);
string(9) "335151580"
```

**generateValidAFM** - Same as `generateAFM` with `$params['valid']` force and override to `true`

- **Returns**: `string` - A valid 9 digit AFM number

Example:

```
generateValidAFM(['pre99' => true]);
string(9) "070825250"
```

**generateInvalidAFM** - Same as `generateAFM` with `$params['valid']` force and override to `false`

- **Returns**: `string` - An invalid 9 digit AFM number

Example:

```
generateInvalidAFM(['legalEntity' => true]);
string(9) "877577341"
```
