Are you trying to pull a phone number out of a longer sequence of text
that may contain other numeric things too, or are you trying to parse it
from a dedicated phone number field?
If the former, the two examples already posted look OK. If the latter, then
you can probably afford to be more forgiving. Here is some code that ought
to be more flexible:
<?php
$phone = '2-45 67598 1...2';
$parsed = parse_phone($phone);
print_r($parsed);
function parse_phone ($string, $country='us')
{
if ($country != 'us')
die("Not implemented yet!");
$retval = array();
$string = preg_replace('/[^0-9]/', '', $string);
if (strlen($string)<10)
$retval['Warning'] = "Phone number too short.";
if (strlen($string)>10)
$retval['Warning'] = "Phone number too long. "
. "Possible extension included.";
$retval['AREA'] = substr($string, 0, 3);
$retval['START'] = substr($string, 3, 3);
$retval['FINISH'] = substr($string, 6, 4);
$retval['EXT'] = substr($string, 10);
return $retval;
}
?>
