PHP, MariaDB, and Google Geocoding
Return   Back To Top
Mixing a bit of PHP that reads in a city-country list from a MariaDB database and the Google JavaScript Geocoding API, I created a quick way to take a peek at some cities throughout the world.

Here it is in action:

Hello World Maps

Map of Manila.

Show me the code.



	require_once ($_SERVER['DOCUMENT_ROOT']."/mobileapp/PDO_hpialcontacts.php") ;
    if (!isset($_GET['city'])) {
    	$city = 'Spring';
    } else {
    	$city = $_GET['city'];
    if (!isset($_GET['country'])) {
    	$country = 'United States of America';
    } else {
    	$country = $_GET['country'];
