如何從ajax請求接收php數組？

Question

我想通過ajax從php文件接收數組，我嘗試了Encode但沒有用，有幫助嗎？

php文件：

$Data = array()
foreach($Query as $User){
    //get Year variable
    if($Year['Year'] == $YearPosted){
        //get Name variable
        $Data['Id'] = $Name['FirstName']." ".$Name['LastName'];

    }
}
echo json_encode($Data);

js文件：

$.ajax({
        type: "post",
        url: "Ajax/Users/GetUsers.php",
        data: {
            year: Year
        },
        success: function (data) {
            alert(data.Id)
        }
    });

我想從php文件接收類似的東西

var User = [{
  "1": "Name of UserId One"
}, {
  "2": "Name of UserId One"
}]

Answer 1

您必須執行以下操作，變量可能未定義，因為您沒有提及表的字段。

PHP的一面

$Data = array()
foreach($Query as $key => $User){

    //get Year variable
    if($Year['Year'] == $YearPosted){
        //get Name variable
        $Data[$key]['Id'] = $Name['FirstName']." ".$Name['LastName'];

    }
}
echo json_encode($Data);

從js方面

$.ajax({
        type: "post",
        url: "Ajax/Users/GetUsers.php",
        data: {
            year: Year
        },
        success: function (data) {
            data = JSON.parse(data);
            console.log(data.id);

        }
    });

嘗試添加新的數組級別：

$Data = array()
foreach($Query as $User){
    //get Year variable
    if($Year['Year'] == $YearPosted){
        //get Name variable
        $Data[] = [$Data['Id'] => $Name['FirstName']." ".$Name['LastName']];
    }
}
echo json_encode($Data);
