zipcode-timezone-php

An overbuilt utility class to convert US ZIP codes to 'tz' timezone strings.

Example:

// import the Timezone class
require_once "/path/to/Timezone.php";

// specify whether or not to use the compressed zipcode data file
// default: false
$timezone = new \Angorb\ZipCodeTimezone\Timezone(true);

echo $timezone->getForZipCode(90120); // prints 'America/Los_Angeles'

echo $timezone->getForZipCode(00000); // invalid ZIP code - prints (bool) 'false' 

// if you're not super concerned with optimization because you have few lookups
// to do, a static method exists
echo \Angorb\ZipCodeTimezone\TimezoneForZip::get(10001); // prints 'America/New_York'
