客户端从服务端下载文件的流程分析：
所以我们需要在php代码中设置一次读取的字节数,比如我在下面的代码中通过$buffer=1024设置一次读取的字节数，每读取一次，就输出数据（即返回给浏览器）
流程图：
("Content-type:text/html;charset=utf-8"
="圣诞狂欢.jpg"
=("utf-8","gb2312",=['DOCUMENT_ROOT']."marcofly/phpstudy/down/down/"=.
(!( "没有该文件文件"=(,"r"=(
("Content-type: application/octet-stream"("Accept-Ranges: bytes"("Accept-Length:".("Content-Disposition: attachment; filename=".=1024=0
(!() && =(,+= (?>
