Try something like this (untested):
$phonenumber = '(123)-123-1234';
$phonenumber = preg_replace('/[^0-9]/','',$phonenumber);
if(!preg_match('/^([0-9]{3})([0-9]{3})([0-9]{4})$/',$phonenumber,$matches){
die('Invalid phone number.');
}
$full_number = $matches[0];
$areacode = $matches[1];
$exchange = $matches[2];
$number = $matches[3]
$banned_exchanges = array('321','654');
if(in_array($exchange,$banned_exchanges)){
die('Bad exchange.');
}

hello,
thank you for your time...
what is the best way for me to have a form field, "phone" reject
certain phone prefixes?
for example: someone enters 321-1791 and "321" prefix can not be
allowed as an entry...
thank you again, addison
