之前已经有很多方法可以通过angular进行本地数据的读取。以前的例子中，大多数情况都是将数据存放到模块的$scope变量中，或者直接利用ng-init定义初始化的数据。但是这些方法都只为了演示其他功能的效果。这次来学习一下如何将Angular和PHP相结合，从后台读取数据。

首先，利用PHP，我们定义了一组后台数据，代码如下（test.PHP）：

<?PHP
header("Access-Control-Allow-Origin: *");
header("Content-Type: application/json; charset=UTF-8");
$conn = new MysqLi("myServer","myUser","myPassword","Northwind");
$result = $conn->query("SELECT CompanyName,City,Country FROM Customers");
$outp = "";
while($rs = $result->fetch_array(MysqLI_ASSOC)) {
    if ($outp != "") {$outp .= ",";}
    $outp .= '{"Name":"'  . $rs["CompanyName"] . '",';
    $outp .= '"City":"'   . $rs["City"]        . '",';
    $outp .= '"Country":"'. $rs["Country"]     . '"}'; 
}
$outp ='{"records":['.$outp.']}';
$conn->close();
echo($outp);
?>

<div ng-app="myApp" ng-controller="customersCtrl"> 
<table>
  <tr ng-repeat="x in names">
    <td>{{ x.Name }}</td>
    <td>{{ x.Country }}</td>
  </tr>
</table>
</div>
<script>
var app = angular.module('myApp',[]);
app.controller('customersCtrl',function($scope,$http) {
    $http.get("test.PHP")
    .success(function (response) {$scope.names = response.records;});
});
</script>
