how to correctly setup ng-repeat with multiple received arrays

I have problem with setting up ng-repeats in angular when I receive some arrays from php. Can anyone please explain it to me ? I would like to have one div for one position of array. Thanks for kind response and here's the code:

Angular

 <div ng-app="ReportRequest" ng-controller="InsertRequest" id="pos">
    <div ng-repeat="row in report.articles.rows" class="position articles">
       <p ng-bind="row"></p
    </div>

Angular ajax request(work's fine)

var RequestApp = angular.module('ReportRequest',[]);

RequestApp.controller('InsertRequest', function ($scope, $http) {
$http.get("functions.php", {
}).then(function success(response) {
    $scope.report = response.data.rows;
  })
});

PHP (are there any mistakes ?)

<?php

header('Content-Type: application/json');

require_once  'db_connect.php';

function retrieveArticle($conn)
{

$prep_stmt = "SELECT * FROM blog";
$stmt = $conn->prepare($prep_stmt);

if ($stmt) {
    $stmt->execute();
    $result = $stmt->get_result();
    //$num_of_rows = $result->num_rows;

    while ($row = $result->fetch_assoc()) {
        //$id = $row['id'];
        $article[] = $row['article'];
    }


}

$stmt->free_result();
$stmt->close();

return $article;
}

$articles = array(retrieveArticle($conn));
$report = array('rows' => $articles);
echo json_encode($report);
