开始想到用$_POST来接受。后来发现行不通。
查阅了很多资料 明白了所以然，这里做一个笔记：

于PHP默认只识别application/x-www.form-urlencoded标准的数据类型。
因此，对型如text/xml 或者 soap 或者 application/octet-stream 之类的内容无法解析，如果用$_POST数组来接收就会失败！
故保留原型，交给$GLOBALS['HTTP_RAW_POST_DATA'] 来接收。

另外还有一项 php://input 也可以实现此这个功能

php://input 允许读取 POST 的原始数据。和 $HTTP_RAW_POST_DATA 比起来，它给内存带来的压力较小，并且不需要任何特殊的 php.ini 设置。php://input和 $HTTP_RAW_POST_DATA 不能用于 enctype="multipart/form-data"。

我在Flash中使用JPGEncoder把BitMapData转成二进制，然后post给php

php页面代码如下：

<?php
$filename="teststream.jpg";//要生成的图片名字
if (!empty($GLOBALS["HTTP_RAW_POST_DATA"]))
{
  $jpg = $GLOBALS["HTTP_RAW_POST_DATA"];//得到post过来的二进制原始数据
  $file = fopen("cache/pic/".$filename,"w");//打开文件准备写入
  fwrite($file,$jpg);//写入
  fclose($file);//关闭
}
?>




这个小东西用于我自己写的通讯录系统。上传裁剪用户头像。
这里先放出图片预览。后头正式发布在给demo和src
