Here I am going to show you how to get coordinates from address using google api based on the town, city or country location.
Let’s start with the following snippet:

<?php
$address = '740 Story Rd San Jose CA 95122';
$coordinates = file_get_contents('http://maps.googleapis.com/maps/api/geocode/json?address=' . urlencode($address) . '&sensor=true');
$coordinates = json_decode($coordinates);
echo 'Latitude:' . $coordinates->results[0]->geometry->location->lat;
echo 'Longitude:' . $coordinates->results[0]->geometry->location->lng;
$latitude = $coordinates->results[0]->geometry->location->lat;
$longitude = $coordinates->results[0]->geometry->location->lng;
?>As you can see above simple piece of code. First, grab the address into a variable (in this case $address), then use file_get_contents and the Google Maps API.
The next step is to decode the JSON string into array using json_decode.
Now, let’s display the Latitude and Longitude results. You should see something like:
Latitude:45.5064121Longitude:-73.6397903
Finally, we have to use these variables in our script for show the location on the map:
<script>
function initialize() {
var mapOptions = {
zoom: 15,
center: new google.maps.LatLng('<?php echo $latitude ?>', '<?php echo $longitude ?>')
};
var map = new google.maps.Map(document.getElementById('map'),
mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>Checkout full code below:
<?php
$address = '3500 Jean Talon Ouest, Montreal, QC H3R 2E8 Canada';
$coordinates = file_get_contents('http://maps.googleapis.com/maps/api/geocode/json?address=' . urlencode($address) . '&sensor=true');
$coordinates = json_decode($coordinates);
$latitude = $coordinates->results[0]->geometry->location->lat;
$longitude = $coordinates->results[0]->geometry->location->lng;
?>
