推荐答案

我相信你想完成（流通过PHP现有的zip文件）可以做类似这里的答案是什么：
<一href=\"http://stackoverflow.com/questions/4357073/on-the-fly-zipping-streaming-of-large-files-in-php-or-otherwise/4357904#4357904\">On-the-fly压缩和解和放大器;大文件，PHP中的流媒体或其他方式

I believe what you're trying to accomplish (stream an existing zip file via php) can be done similar to the answer here: On-the-fly zipping & streaming of large files, in PHP or otherwise

从这个答案code稍微修改后的版本：

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);
