如何将ByteArray(从Flash)和一些表单数据发送到php？

import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.net.URLVariables;

var url:String = "http://yourserver.com/yourscript.php";
var request:URLRequest = new URLRequest(url);
request.method = URLRequestMethod.POST;

var variables:URLVariables = new URLVariables();
variables.data = byteArray;
variables.formData = "your form data here";
request.data = variables;

var loader:URLLoader = new URLLoader();
loader.load(request);

import flash.net.FileReference;

var fileRef:FileReference = new FileReference();
fileRef.save(byteArray, "filename.ext");

fileRef.addEventListener(Event.COMPLETE, onSaveComplete);

function onSaveComplete(event:Event):void {
    var request:URLRequest = new URLRequest("http://yourserver.com/yourscript.php");
    request.method = URLRequestMethod.POST;

    var variables:URLVariables = new URLVariables();
    variables.formData = "your form data here";
    request.data = variables;

    fileRef.upload(request);
}

<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    // Access form data
    $formData = $_POST['formData'];

    // Access uploaded file
    $file = $_FILES['Filedata'];
    $fileName = $file['name'];
    $fileType = $file['type'];
    $fileSize = $file['size'];
    $fileTempName = $file['tmp_name'];

    // Save the uploaded file
    move_uploaded_file($fileTempName, "uploads/$fileName");
}
?>
