AngularJS http php echo

Question

我想從一個PHP腳本獲取數據到我的角度應用程序。我正在使用此代碼來獲取數據。然而，它失敗了，然後給我沒有信息爲什麼。

var req = { 
     method: 'GET', 
     url: 'http://www.hott-source.com/hangman/getMemory.php', 
     data: { } 
    } 

    $http(req).then(function(response){ 
     alert("WINNER"); 
     $scope.knownWords = response.data; 
    }, function(response){ 
     alert(response.data); 
    }); 

的PHP腳本返回

[ 
    ["A","I"], 
    ["BE","BY","DO","GO","IN","ME","MY"], 
    ["CAT","COW","DOG","GOD","HIT","MAT","PAT","PIG","RUN","YOU"], 
    ["BAND","BIRD","CART","CHIP","DOVE","JUMP","LOVE","READ"], 
    ["CHIRP","HAPPY","HORSE"], 
    ["CHURCH","HANSON","HITTER","PEOPLE","PRIEST","STRIKE","THOMAS"], 
    ["BELINDA","BUILDER","SHOOTER"], 
    ["CLAPPING","ELEPHANT"], 
    ["COLLECTION"] 
] 

我已經驗證爲JSON。在PHP文件我設置頁眉內容類型爲JSON之前我把它

header('Content-Type: application/json'); 
echo json_encode($newArray); 

response.data警報爲空

我如何從PHP腳本中的數據到我的$範圍。 knownWords

腳本getMemory.php必須返回access-control-allow-origin HTTP標頭：

header('access-control-allow-origin: *')
