var myModule = angular.module("HelloAjax",[]);
myModule.controller("HelloAjax",["$scope","$http",function HelloAjax($scope,$http){
  /*
  $scope.users=[{&#39;username&#39;:"zhangsan","email":"zs@11.com"},
    {&#39;username&#39;:"zhangsan2","email":"zs@22.com"},
    {&#39;username&#39;:"zhangsan3","email":"zs@33.com"}];
  */
  $scope.get_more = function(){
    $http({
        method: "POST",
        url: "./ajax.php",
        data:{&#39;username&#39;:$scope.username,
           &#39;email&#39;:$scope.email
          }
      }).
      success(function(data, status) {
       //$scope.status = status;
        $scope.users = data;
      }).
      error(function(data, status) {
       //$scope.data = data || "Request failed";
       //$scope.status = status;
     });
   }
}]);

【PHP代码 ajax.php】

<?php
//获取参数
$data = file_get_contents("php://input");
$user = json_decode($data);
//查询数据库
$conn = mysql_connect("localhost","root","");
mysql_select_db("test");
$sql ="select username,email from users ";
$res = mysql_query($sql,$conn);
$users = array();
while($row = mysql_fetch_assoc($res)){
  $users[] = $row;
}
//当然这里简化了插入数据库
$users[] = array(&#39;username&#39;=>$user->username,
         &#39;email&#39;=>$user->email);
//返回数据库
echo json_encode($users);
