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

Answer 2

(.+?), (\w+) ([-\d]+)

Then get the info from the capturing groups.

Answer 3

Why not do.

/(?P<city>[^,]+),\s*(?P<state>\w{2})\s*(?P<zip>\d{5}(?:-\d{4})?)/

Saves you doing:

$arr['city'] = $matches[1];
$arr['state'] = $matches[2];
$arr['zip'] = $matches[3];

so when you:

print_r($matches);

you will get

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

Main expression used from NullUserException and all credit goes to him. I just shortened the process.
