Parse Full USA Street Address into Address, City, State, Zip

I have addresses that follow this format every time:

Address, City, State Zip

Example: 555 Test Drive, Testville, CA 98773

I would like to parse the address into separate variables for:

I have tried some preg_match examples but they don't follow the same pattern I am using. Is it regex or preg_match im looking for? Please help!

Solution

If you are absolutely positive the addresses will always be formatted just like your example, with those commas, you have two simple options.

preg_match("/(.+), (\w+), (\w+) (\w+)/", $address, $matches);
list($original, $street, $city, $state, $zip) = $matches;

Now you have your individual address variables.

You can also use explode() to pull apart the address into pieces:

list($street, $city, $statezip) = explode(", ", $address);
list($state, $zip) = explode(" ", $statezip);
