 it works, but I think creating the file in memory is a better
 approach, so I changed the 2nd lineI(using php 5.2.0) to
 $filename = 'php://temp/xxx.zip';
 then the php just won't archive the file and the file downloaded is
 just a plain text file.

 so
 question 1, how to create zip Archive file in memory on the fly and
 download it (I don't have to save it on disk)?
 question 2, if there is no way to create in memory, is it safe to just
 unlink() the file?

 thanks in advance.

 According to http://docs.php.net/manual/en/wrappers.php.php, it looks
 like you should be using ...

 $filename = 'php://temp';

 That's it.

 The actual file name is not your job.

It looks like this isn't possible.

[PHP] create archive file in memory with zipArchive class

2010-02-09 Thread Ryan Sun 
I want to generate credential zip file for user on the fly with
zipArchive and render it for download, so I created following code
-
$zip = new ZipArchive();
$filename = '/tmp/xxx.zip';
if ($zip-open($filename, ZIPARCHIVE::CREATE)!==TRUE) {
 throw new Exception();
}
if($zip)
{
    $zip-addFromString('xxx.xx', $fileString);
}
$zip-close();
$fileString = file_get_contents($filename);
unlink($filename);

$this-getResponse()-setHeader('Content-Type', 'application/zip');
$this-getResponse()-setHeader('Content-Disposition','attachment;filename=xxx.zip');
$this-getResponse()-setBody($fileString);
-
it works, but I think creating the file in memory is a better
approach, so I changed the 2nd lineI(using php 5.2.0) to
$filename = 'php://temp/xxx.zip';
then the php just won't archive the file and the file downloaded is

question 2, if there is no way to create in memory, is it safe to just
unlink() the file?
