You can use the ZipArchiveclass to create a ZIP file and stream it to the client. Something like:
您可以使用ZipArchive该类创建 ZIP 文件并将其流式传输到客户端。就像是：
$files = array('readme.txt', 'test.html', 'image.gif');
$zipname = 'file.zip';
$zip = new ZipArchive;
$zip->open($zipname, ZipArchive::CREATE);
foreach ($files as $file) {
$zip->addFile($file);
}
$zip->close();
and to stream it:
并流式传输它：
header('Content-Type: application/zip');
header('Content-disposition: attachment; filename='.$zipname);
header('Content-Length: ' . filesize($zipname));
readfile($zipname);
The second line forces the browser to present a download box to the user and prompts the name filename.zip. The third line is optional but certain (mainly older) browsers have issues in certain cases without the content size being specified.
第二行强制浏览器向用户呈现一个下载框并提示名称 filename.zip。第三行是可选的，但某些（主要是较旧的）浏览器在某些情况下会出现问题，而没有指定内容大小。

This is a working example of making ZIPs in PHP:
这是在 PHP 中制作 ZIP 的工作示例：
$zip = new ZipArchive();
$zip_name = time().".zip"; // Zip name
$zip->open($zip_name, ZipArchive::CREATE);
foreach ($files as $file) {
echo $path = "uploadpdf/".$file;
if(file_exists($path)){
$zip->addFromString(basename($path), file_get_contents($path));
}
else{
echo"file does not exist";
}
}
$zip->close();

您已准备好使用 php zip lib，也可以使用 zend zip lib，
<?PHP
// create object
$zip = new ZipArchive();
// open archive
if ($zip->open('app-0.09.zip') !== TRUE) {
die ("Could not open archive");
}
// get number of files in archive
$numFiles = $zip->numFiles;
// iterate over file list
// print details of each file
for ($x=0; $x<$numFiles; $x++) {
$file = $zip->statIndex($x);
printf("%s (%d bytes)", $file['name'], $file['size']);
print "
";
}
// close archive
$zip->close();
?>

Create a zip file, then download the file, by setting the header, read the zip contents and output the file.
创建一个 zip 文件，然后下载文件，通过设置标题，读取 zip 内容并输出文件。
