我如何可以通过从PHP为ActionScript 3 /闪存阵列？ [英] How can I pass an array from PHP to Actionscript 3/Flash?

问题描述

下面是我在PHP：

for ($i = 0; $i < 355; $i++)
{
    echo "vote";
    echo "$i";
    echo "=$votesArray[$i]";
    if($i != 354)
    {
        echo "&";
    }
}

这应该将数据发送给Flash，看起来像vote0 = 2及vote1 = 5和......等等

Which should send data to Flash that looks something like "vote0=2&vote1=5&..." and so on.

下面是ActionScript 3方：

Here is the Actionscript 3 side:

var i:int;
for (i = 0; i < 355; i++)
{
    var tempString:String = "vote" + i; 
    voteResults[i] = event.target.data.tempString;
}

我还没有尝试运行这个还没有，但我得到它不会工作的感觉。你可以看到我想要知道的有关系吗？对于每个迭代循环，我想它从event.target.data的不同部分取数据。对于第一次迭代，应当event.target.data.vote0。第二，event.target.data.vote1，等等。

I haven't attempted to run this yet, but I get the feeling it won't work. Can you see what I'm trying to get at, though? For each iteration of the for loop, I would like it to take the data from a different part of event.target.data. For the first iteration, it should be event.target.data.vote0. Second, event.target.data.vote1, and so on.

推荐答案

我会用XML这样的事情，但它可以通过URL连接codeD字符串来完成。

I would use xml for something like this, but it can be done with url encoded strings.

假设你加载了数据URLLoader和指定的DATAFORMAT为<一个href="http://www.adobe.com/livedocs/flash/9.0/ActionScriptLangRefV3/flash/net/URLLoaderDataFormat.html"相对=nofollow> URLLoaderDataFormat.VARIABLES 中，你靠近。

Assuming you loaded your data with URLLoader and specified the dataFormat as URLLoaderDataFormat.VARIABLES, you are close.

如果你有一个原始字符串，你应该先分析其分解为名称/值对。这是的URLVariables 一样。

If you have a raw string, you should parse it first to break it down to name/value pairs. This is what URLVariables does.

总之，一旦你有一个包含名称/值的对象，你可以这样做：

Anyway, once you have an object containing names/values, you can do:

var i:int;
for (i = 0; i < 355; i++)
{
    var tempString:String = "vote" + i; 
    voteResults[i] = event.target.data[tempString];
}

如果您使用点访问，将采取tempString的字面。如果使用托架访问，可变tempString的值进行评估。

If you use dot access, it will take "tempString" literally. If you use bracket access, the value of the variable tempString will be evaluated.

PS：顺便说一句，我不认为你的PHP会做你想做的。一个清洁的方式，IMO是：

PS: By the way, I don't think your php will do what you want. A cleaner way, IMO would be:

$pairs = array();
for ($i = 0; $i < 355; $i++)
{
    $pairs[] = 'vote' . $i . '=' . $votesArray[$i]; 
    // you might want to use rawurlencode($votesArray[$i]) to be safe if these are not numeric values.
}
echo implode('&',$pairs);

PS 2：此外，这是相当脆弱，因为你硬编码355如果你改变你的PHP，你必须改变你的AS code为好。你可以尝试这样的：

PS 2: Also, this is rather brittle since you're hardcoding 355. If you ever change your php, you'll have to change your AS code as well. You could try something like this:

var data:URLVariables = event.target.data as URLVariables;
for(var fieldName:String in data) {
    var index:int = parseInt(fieldName.substr(4));
    //  or optionally, add an underscore to the name: vote_1
    //  so you can change the above to something like
    //  fieldName.split("_")[1]
    voteResults[index] = data[fieldName];
}

或者，正如我以前，你可以使用XML，这是很简单和一个更好的选择，这个说，我想。

Or, as I said before, you could use xml, which is simple enough and a better option for this, I think.
