Angular.js如何从PHP读取后台数据

<"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); 
"SELECT CompanyName, City,Country FROM Customers")）。之后，利用循环结构，将取出的数据以键值对的形式保存在$outp变量中。

接下来，在js中操作如下：



<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> 



 这里仍然应用了$http服务进行数据的读取，传入数据文件对应的url路径，成功后返回数据，并绑定到$scope.names变量上。
