Check digits (or characters) are a 'checksum' on a number to help prevent manual typing errors. Follow Norma ISO 7064 Mod 97-10. Usaded IBAN and NIB validation

Description

Algorithm that calculates number of control, described in ISO 7064, Mod 97 10. Normally used to validate IBAN and nibs of bank accounts.

Methods

class ISO7064Mod97_10
    - encode( string/integer $input )
        return checksum number
    - verify( string/integer $input )
        verify if input are valid with your check digits
    - checkCode( string/integer $input )
        return only check digits of input
    - computeCheck( string/integer $input )
        return mod 97 of input
    - getCheck( string/integer $input )
        return only chek digits of input
    - getData( string/integer $input )
        return value of input without check digits

Example

require 'ISO7064Mod97_10.php'
$c = new ISO7064Mod97_10();
$n = 107571;
$yourNum = $c->encode($n);
var_dump($yourNum);
//int(10757107)
var_dump($c->verify($yourNum));
$validNumber = '10757107';
$invalidNumber = '10767107';
var_dump($c->verify($validNumber));
var_dump($c->verify($invalidNumber));
