README

Validate and generate Greek TIN (Tax Identification Number) / AFM (Αριθμός Φορολογικού Μητρώου). Generation function can create valid or invalid numbers including parameters for old format, individuals, legal entities and repet tolerance digits control.

Installation

composer require lytrax/afm

Usage

Use one or more functions:

use function Lytrax\AFM\validateAFM;
use function Lytrax\AFM\generateAFM;
use function Lytrax\AFM\generateValidAFM;
use function Lytrax\AFM\generateInvalidAFM;

Validate a number:

validateAFM('090000045');
bool(true)

validateAFM('123456789');
bool(false)

Generate a valid number:

generateValidAFM();
string(9) "731385437"

Generate an invalid number:

generateInvalidAFM();
string(9) "853003357"

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"
