AngularJS中的简单数据库搜索引擎

我正在尝试在AngularJS中创建一个简单的搜索引擎。我的客户端与服务器之间的通信存在问题。我正在尝试遵循w3schools指南http://www.w3schools.com/angular/angular_sql.asp

这是home.php正文:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js">      
</script> 
</head>

<body>
<div ng-app="myApp" ng-controller="customersCtrl"> 
<table>
    <tr ng-repeat="x in names">
        <td>{{ x.Name }}</td>
    </tr>
</table>
</div>

<script>
var app = angular.module('myApp', []);
app.controller('customersCtrl', function($scope, $http) {
    $http.get("server.php")
    .then(function (response) {$scope.names = JSON.parse(response.data.records);});

});

</script>

这里是server.php:

<?php
header("Access-Control-Allow-Origin: *");
header("Content-Type: application/json; charset=UTF-8");
error_reporting(2);

$conn = new PDO('mysql:host=localhost;dbname=mygaloo;charset=utf8', 'root',    ''); 
$result = $conn->query("SELECT * FROM associations"); 
$outp = "";

while($donnees = $query->fetch()) 
{
    if ($outp != "") {$outp .= ",";}
    $outp .= '{"Name":"'  . $donnees["nom"] . '"}';
}

$outp ='{"records":['.$outp.']}';
$conn->close();


echo($outp);
?>

然而,我得到了这个错误: angular.js:12520SyntaxError:位于0的JSON中的意外标记u ,有什么想法吗?

这是你的角度代码

<script>
        var app = angular.module('myApp', []);
        app.controller('customersCtrl', function($scope, $http) {   
                $http.get("server.php")
                .then(function (response) {
                    $scope.names = response.data;
                }).then(function(response){
                    console.log(response)
                })

        });
    </script>

这是你的PHP代码。希望它会对你有所帮助。

<?php
  header("Access-Control-Allow-Origin: *");
  header("Content-Type: application/json; charset=UTF-8");

  $conn = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'root', ''); 
  $result = $conn->query("SELECT * FROM associations"); 
  $outp = [];
  while($rs = $result->fetch(MYSQLI_ASSOC)) {
    if ($outp != "")
    array_push($outp,$rs["nom"]);
  }
 $outp =json_encode($outp);
 $conn = null;
 echo($outp);
?>

好的,我明白了。 Arun Shinde的回答是对的,但问题来自:

while($rs = $result->fetch(MYSQLI_ASSOC)) {

我正在使用PDO,所以在这里使用MYSQLI显然不会起作用。 所以这里有完整的代码。 home.php:

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8" />
    <script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js">     
    </script> 
</head>

<body>
    <div ng-app="myApp" ng-controller="customersCtrl"> 
    <table>
        <tr ng-repeat="x in names"> <td>{{ x }}</td> </tr>
    </table>
    </div>

    <script>
    var app = angular.module('myApp', []);
    app.controller('customersCtrl', function($scope, $http) {   
            $http.get("server.php")
            .then(function (response) {
                $scope.names = response.data;
            }).then(function(response){
                console.log(response)
            })

    });
    </script>
</body>

server.php:

<?php
header("Access-Control-Allow-Origin: *");
header("Content-Type: application/json; charset=UTF-8");

$conn = new PDO('mysql:host=localhost;dbname=mygaloo;charset=utf8', 'root', ''); 
$result = $conn->query("SELECT * FROM associations"); 
$outp = [];
while($rs = $result->fetch()) {
    if ($outp != "")
    array_push($outp,$rs["nom"]);
}
$outp =json_encode($outp);
$conn = null;
echo($outp);
?>

非常感谢大家的耐心!
