php转换为zip并下载 [英] php convert to zip and download

问题描述

我想将文件转换为zip并使其可供用户下载，此zip文件是在运行时创建的。

对于此即时通讯使用代码来自

http ：//www.9lessons.info/2012/06/creating-zip-file-with-php.html？m = 1

工作正常，但是当创建的拉链尺寸很大时，即30 mb ，我无法下载，因为下载的filze大小只有1或2 kb

（而不是30 mb），虽然在服务器上创建的zip文件大约是30mb

什么可以问题

I want to convert files to zip and make it available for user to download, this zip files are created at runtime.
For this i m using code from
http://www.9lessons.info/2012/06/creating-zip-file-with-php.html?m=1
It works fine but when size of zip created is large ie 30 mb, i am unable to download as downloaded filze size is just 1 or 2 kb
(Instead of 30 mb),though zip file created on server is about 30mb
What could be problem

推荐答案

请使用： http：// php.net/manual/en/book.zip.php [ ^ ]。



直接在HTTP响应中提供ZIP文件（不存储文件和使用HTTL 锚点元素），指定HTTP标题''Content-type：application / zip''：

Please use: http://php.net/manual/en/book.zip.php[^].

To provide a ZIP file on the fly, directly in HTTP response (without storing a file and using HTTL anchor element), specify the HTTP header ''Content-type: application/zip'':

header('Content-type: application/zip');

另请参阅：
