推荐答案

我相信你想要完成什么（通过php流式传输现有的zip文件）可以类似于这里的答案：
LAMP：如何创建。为用户提供大文件的Zip，无磁盘/ CPU抖动

I believe what you're trying to accomplish (stream an existing zip file via php) can be done similar to the answer here: LAMP: How to create .Zip of large files for the user on the fly, without disk/CPU thrashing

该答案稍微修改后的版本代码：

Slightly modified version of code from this answer:

// make sure to send all headers first
// Content-Type is the most important one (probably)
//
header('Content-Type: application/x-gzip');

$filename = "/path/to/zip.zip";
$fp = fopen($filename, "rb");

// pick a bufsize that makes you happy
$bufsize = 8192;
$buff = '';
while( !feof($fp) ) {
   $buff = fread($fp, $bufsize);
   echo $buff;
}
pclose($fp);
