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'); # $bn = '54362315'
DESCRIPTION
ALGORITHM
- 1.
- The checkdigit is the whole number taken modulo 23 and coded according to a keytable.
METHODS
- is_valid($number)
- Returns true only if $number consists solely of numbers and the last digit is a valid check digit according to the algorithm given above.
Returns false otherwise,
- complete($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 $number has a valid check digit.
Return '' otherwise.
