Find Distance Between two Addresses using Google API and PHP

Last updated on August 31st, 2017 by Paritosh Pandey


In this article you are going to learn how you can find distance between two addresses. We are going to use google map api and PHP to accomplish this task.

The Module we are going to develope here is basically an API provided by Google itself. This API can measure distance between two locations as well as Travel Time.

The format for origin location and destination location could be one of the following:

  • place name (e.g. Bhopal,India)
  • ZIP code (e.g. 462016)
  • latitude/longitude coordinates (e.g. 23.77xxx, 77.30xxx)

to know more about permissible formats please visit googl’s official documentation page.

        <?php
            if(isset($_POST['submit'])){
            $origin = $_POST['o']; $destination = $_POST['d'];
            $api = file_get_contents("https://maps.googleapis.com/maps/api/distancematrix/json?units=imperial&origins=".$origin."&destinations=".$destination."&key=YOUR_API_KEY");
            $data = json_decode($api);
        ?>

            <label><b>Distance: </b></label> <span><?php echo ((int)$data->rows[0]->elements[0]->distance->value / 1000).' Km'; ?></span> <br><br>
