Answer 1

Try this regex:

/([^,]+),\s*(\w{2})\s*(\d{5}(?:-\d{4})?)/

Translated into code:

$str = "New York, NY 50805-2578";
preg_match("/([^,]+),\s*(\w{2})\s*(\d{5}(?:-\d{4})?)/", $str, $matches);

list($arr['addr'], $arr['city'], $arr['state'], $arr['zip']) = $matches;
print_r($arr);

Gives:

Array
(
    [zip] => 50805-2578
    [state] => NY
    [city] => New York
    [addr] => New York, NY 50805-2578
)

With this regex:

• There is some input validation (eg: requires input to be in the form of: XXXXXXX, YY NNNNN-NNNN)

• Spaces are optional

• The last 4 digits of the zip are optional
