问题描述
我正在尝试通过在本地服务器上创建zip文件来下载2个文件。该文件以zip格式下载,但是当我尝试提取it.it时会出错:
结束 - 未找到中心目录签名。这个文件不是
的zip文件,或者它构成一个多部分存档的一个磁盘。在
后一种情况下,中央目录和zip文件注释将在
上找到此存档的最后一个磁盘。
I am trying to download a 2 files by creating the zip file on local-server.the file is downloaded in zip format but when i try to extract it.it gives error:End-of-central-directory signature not found. Either this file is not a zip file, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zip file comment will be found on the last disk(s) of this archive.
以下我正在使用的代码:
the following code i am using for this:
<?php
$file_names = array('iMUST Operating Manual V1.3a.pdf','iMUST Product Information Sheet.pdf');
//Archive name
$archive_file_name=$name.'iMUST_Products.zip';
//Download Files path
$file_path=$_SERVER['DOCUMENT_ROOT'].'/Harshal/files/';
zipFilesAndDownload($file_names,$archive_file_name,$file_path);
function zipFilesAndDownload($file_names,$archive_file_name,$file_path)
{
//echo $file_path;die;
$zip = new ZipArchive();
//create the file and throw the error if unsuccessful
if ($zip->open($archive_file_name, ZIPARCHIVE::CREATE )!==TRUE) {
exit("cannot open <$archive_file_name>\n");
}
//add each files of $file_name array to archive
foreach($file_names as $files)
{
$zip->addFile($file_path.$files,$files);
//echo $file_path.$files,$files."
}
$zip->close();
//then send the headers to force download the zip file
header("Content-type: application/zip");
header("Content-Disposition: attachment; filename=$archive_file_name");
header("Pragma: no-cache");
header("Expires: 0");
readfile("$archive_file_name");
exit;
}
?>
我检查了所有传入函数的变量都很好,请看这个。谢谢提前。
i checked the values of all variables which are passing into the function,all are fine.so please look this.Thanks in advance.
推荐答案
添加内容长度
标题描述zip文件的大小(以字节为单位)。
Add Content-length
header describing size of zip file in bytes.
header("Content-type: application/zip");
header("Content-Disposition: attachment; filename=$archive_file_name");
header("Content-length: " . filesize($archive_file_name));
header("Pragma: no-cache");
header("Expires: 0");
readfile("$archive_file_name");
还要确保在 和
?>
之后。我在这里看到一个空格:
Also make sure that there is absolutely no white space before <?
and after ?>
. I see a space here:
↓
<?php
$file_names = array('iMUST Operating Manual V1.3a.pdf','iMUST Product Information Sheet.pdf');
