Question

我在AS3中创建了一个我需要保存到数据库的tilemap，系统工作正常。当用户创建一个帐户时，会自动为他们创建一个地图（它始终是相同大小的地图，有树木，岩石等11x11）。

[18, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 20],
[3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 11, 0, 0, 0, 0, 0, 0, 0, 0, 0, 17],
[3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 9, 0, 0, 0, 0, 0, 0, 0, 0, 0, 17],
[3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 17],
[3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 17],
[3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 11, 11, 11, 0, 0, 0, 0, 0, 0, 0, 0, 17],
[3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 11, 11, 0, 0, 0, 0, 0, 0, 0, 0, 17],
[3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 11, 11, 0, 0, 0, 0, 0, 0, 0, 0, 0, 17],
[3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 11, 0, 0, 0, 0, 0, 0, 0, 0, 0, 17],
[3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 17],
[7, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 5],

如何将此保存到mysqli数据库然后获取信息并将其返回到AS3脚本？我知道如何从AS3发布，我知道如何从页面获取信息。我已经将整个数组保存在一个名为tileMap的列下，然后当我尝试从表中查询tileMap时...没有返回任何内容。是因为我使用的是[ ]大括号吗？我真的不知道如何展示这个。

你可以序列化/反序列化你的数据，恕我直言保存JSON格式的数据库数据会很好，因为它很容易在Object（）中转换这样的数据因此也在数组中。）

//this function converts data from Array to Object, we need Object for easy JSON conversation afterwards
function toObject(array:Array):Object
{
        var obj:Object = {};
        for (var i:int = 0; i < array.length; ++i)
        {
            obj[i] = array[i];
        }
        return obj;
}

//this converts Object To Array 
function toArray(obj:Object):Array
{
        var arr:Array = [];
        for (var i in obj)
        {
            if (obj.hasOwnProperty(i))
            {
                arr.push(obj[i]);
            }
        }
        return arr;
}

//it's you array
var arr:Array = [[18, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 20], [3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 11, 0, 0, 0, 0, 0, 0, 0, 0, 0, 17], [3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 9, 0, 0, 0, 0, 0, 0, 0, 0, 0, 17], [3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 17], [3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 17], [3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 11, 11, 11, 0, 0, 0, 0, 0, 0, 0, 0, 17], [3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 11, 11, 0, 0, 0, 0, 0, 0, 0, 0, 17], [3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 11, 11, 0, 0, 0, 0, 0, 0, 0, 0, 0, 17], [3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 11, 0, 0, 0, 0, 0, 0, 0, 0, 0, 17], [3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 17], [7, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 5]];

var jsonString:String = JSON.stringify(toObject(arr)); //we got JSON string which for example could be saved as TEXT data in MySQL via PHP      
var onceMoreArray:Array=toArray(JSON.parse(jsonString)); //We can convert JSON string back to array

希望这种方法有所帮助。

从矩阵中创建一个字符串。

[1,0,2],
[2,3,4],
[0,1,5]

成为
