废话少说，先看flash代码，在flash中新建一个文档，放上两个button，一个progressbar组件：
import flash.net.FileReference;
import mx.controls.Alert;

var my_pb:mx.controls.ProgressBar;
var maxSize = 1000*1000*5; //文件大小限制：5M
//设置进度栏模式
my_pb.mode = "manual";
my_pb.label = "上传进度:%1%";
//进度栏增加前的最小数值
my_pb.minimum = 0;
// 进度栏停止前的最大值
my_pb.maximum = 100;
var increment_num:Number = my_pb.minimum;

var allTypes:Array = new Array();
var imageTypes:Object = new Object();
imageTypes.description = "Images (*.jpg, *.jpeg, *.gif, *.png)";
imageTypes.extension = "*.jpg; *.jpeg; *.gif; *.png";
allTypes.push(imageTypes);

var textTypes:Object = new Object();
textTypes.description = "Text Files (*.txt, *.rtf)";
textTypes.extension = "*.txt;*.rtf";
allTypes.push(textTypes);

var flvType:Object =new Object();
flvType.description ="flv Files (*.flv)";
flvType.extension ="*.flv";
allTypes.push(flvType);

// 定义警告确认后的动作。
var myClickHandler:Function = function (evt_obj:Object) {
if (evt_obj.detail == Alert.OK) {
trace("start stock app");
}
};

var listener:Object = new Object();

listener.onSelect = function(file:FileReference):Void {
trace("onSelect: " + file.name);
//if(!file.upload("http://localhost/upfiles/hlp.php")) {
// trace("Upload dialog failed to open.");
//}
    if (file.size<=maxSize)
    {
      //strState.text = "您选择得文件：" + file.name + "\n";
      btnUpload.enabled = true;
    }else
    {
      msg( "对不起您选择的文件太大！");
      btnUpload.enabled = false;
    }
}

listener.onCancel = function(file:FileReference):Void {
trace("onCancel");
}

listener.onOpen = function(file:FileReference):Void {
trace("onOpen: " + file.name);
}

listener.onProgress = function(file:FileReference, bytesLoaded:Number, bytesTotal:Number):Void {
trace("onProgress with bytesLoaded: " + bytesLoaded + " bytesTotal: " + bytesTotal);
    my_pb.setProgress ((bytesLoaded / bytesTotal) * 100, my_pb.maximum);
}

listener.onComplete = function(file:FileReference):Void {
trace("onComplete: " + file.name);
    msg("上传完毕！");
}

listener.onHTTPError = function(file:FileReference):Void {
trace("onHTTPError: " + file.name);
    msg("onHTTPError: " + file.name);
}

listener.onIOError = function(file:FileReference):Void {
trace("onIOError: " + file.name);
    msg("onIOError: " + file.name);
}

listener.onSecurityError = function(file:FileReference, errorString:String):Void {
trace("onSecurityError: " + file.name + " errorString: " + errorString);
    msg("onSecurityError: " + file.name + " errorString: " + errorString);
}

var fileRef:FileReference = new FileReference();
fileRef.addListener(listener);
this.btnBrowse.onRelease = function () {
    fileRef.browse(allTypes);
};
this.btnUpload.onRelease = function () {
    if(!fileRef.upload("http://localhost/upfiles/upfile3.php")) {
trace("Upload dialog failed to open.");
}
    // 显示警告对话框。

}
function msg(msgtxt:String) {
    Alert.show(msgtxt, "消息", Alert.OK , this, myClickHandler, "stockIcon", Alert.OK);
}
php文件很简单：
<?php
// Flash 传递的文件表单 name 属性为 Filedata
$fileName = $_FILES["Filedata"]["name"];
$file = $_FILES["Filedata"]["tmp_name"];
$path = "uploadFiles/";
if (move_uploaded_file($file, $path . $fileName)){
// echo 1;
}else{
// echo 0;
}
?>
