Just some code that validates a ABN (Australian Business Number), uses modulus 89.
Its pretty simple but may be handy for someone out there.
<?
//Validate an ABN
public function validate_abn($abn){
$digit ;
$sum ;
$length = strlen($abn) ;
$weighting = Array(10,1,3,5,7,9,11,13,15,17,19) ;
for($i=0;$i<$length;$i++){
$digit = substr($abn,$i,1) ;
if($i == 0){
$digit -= 1 ;
}
$sum += ($digit*$weighting[$i]) ;
}
if($sum % 89 == 0){
return TRUE ;
}
else{
return FALSE ;
}
}
?>
