How can I save google maps api route information with symfony to database

Im learning Symfony and working on an application. I create a map and make direction information for destination point.

enter image description here

I need to save this direction information to database. But I dont know how can I do. Maybe I convert this direction infotmation to array but I dont know how.
Here is script for map and calculate route

      `<script type="text/javascript">
var source, destination;
var directionsDisplay;
var directionsService = new google.maps.DirectionsService();
google.maps.event.addDomListener(window, 'load', function () {
    new google.maps.places.SearchBox(document.getElementById('txtSource'));
    new google.maps.places.SearchBox(document.getElementById('txtDestination'));
    directionsDisplay = new google.maps.DirectionsRenderer({ 'draggable': true });

function GetRoute() {
    var karabuk= new google.maps.LatLng(41.20488, 32.62768);

    var mapOptions = {
        zoom: 11,
        center: karabuk
    map = new google.maps.Map(document.getElementById('dvMap'), mapOptions);

    //*********DIRECTIONS AND ROUTE**********************//
    source = {lat:41.206373, lng:32.659379};
    destination = document.getElementById("txtDestination").value;

    var request = {
        origin: source,
        destination: destination,
        travelMode: google.maps.TravelMode.DRIVING
    directionsService.route(request, function (response, status) {
        if (status == google.maps.DirectionsStatus.OK) {

    //*********DISTANCE AND DURATION**********************//
    var service = new google.maps.DistanceMatrixService();
        origins: [source],
        destinations: [destination],
        travelMode: google.maps.TravelMode.DRIVING,
        unitSystem: google.maps.UnitSystem.METRIC,
        avoidHighways: false,
        avoidTolls: false
    }, function (response, status) {
        if (status == google.maps.DistanceMatrixStatus.OK && response.rows[0].elements[0].status != "ZERO_RESULTS") {
            var distance = response.rows[0].elements[0].distance.text;
            var duration = response.rows[0].elements[0].duration.text;
            var dvDistance = document.getElementById("dvDistance");
            dvDistance.innerHTML = "";
            dvDistance.innerHTML += "Distance: " + distance + "<br />";
            dvDistance.innerHTML += "Duration:" + duration;

        } else {
            alert("Unable to find the distance via road.");

    var route=directionsDisplay.setDirections(response);



I have defined a column in the database with type array. I didnt find how can I convert direction information to array and save it.
