NAME¶
CheckDigits::M23_001 - compute check digits for DNI (ES)
SYNOPSIS¶
use Algorithm::CheckDigits;
$dni = CheckDigits('dni_es');
if ($dni->is_valid('54362315K')) {
# do something
}
$cn = $dni->complete('54362315');
# $cn = '54362315K'
$cd = $dni->checkdigit('54362315K');
# $cd = 'K'
$bn = $dni->basenumber('54362315K');
# $bn = '54362315'
DESCRIPTION¶
ALGORITHM¶
- 1.
- The checkdigit is the whole number taken modulo 23 and coded according to a keytable.

- is_valid($number)
- Returns true only if $number consists solely of

Returns false otherwise,
- complete($number)
- The check digit for $number is computed and
concatenated to the end of $number.
Returns the complete number with check digit or '' if $number does not consist solely of digits and spaces.
- basenumber($number)
- Returns the basenumber of $number if
$number has a valid check digit.
Return '' otherwise.
- checkdigit($number)
- Returns the checkdigit of $number if
