Getting data from PHP to table in Angular

I know it sounds like a repost but I still have to ask how I can do this in my project.

I have a class in PHP handling API-calls and receiving data. This received JSON data I would like to pass to Angular and present it in UI-Grid. Furthermore the page that I'm working with is in PHP and echoes the HTML for the Angular grid. How can I make it use the previously loaded data from the API?

I've seen many answers to other peoples very similar problems but haven't been able to make them work.

EDIT:

So inside the php I have:

<div ng-controller="DataController as dataCtrl">
<script type="text/javascript">
    var data = <?php echo json_encode(apicall("dummyarg")); ?>;
    //PASS TO ANGULAR
    //$scope.data = $window.data; doesnt work
</script>
</div>

And in js I have:

(function() {
    var app = angular.module('table', ['ngTouch', 'ui.grid']);
    app.controller("DataController", ["$scope", '$window', function($scope, $window){

        $scope.data = {};

    }]);
})();
