Create zip with PHP adding files from url
提问by ngplayground
I was wondering if the following is possible to do and with hope someone could potentially help me.
我想知道是否可以执行以下操作，并希望有人可以帮助我。
I would like to create a 'download zip' feature but when the individual clicks to download then the button fetches images from my external domain and then bundles them into a zip and then downloads it for them.
我想创建一个“下载 zip”功能，但是当个人点击下载时，该按钮会从我的外部域中获取图像，然后将它们捆绑到一个 zip 文件中，然后为他们下载。
I have checked on how to do this and I can't find any good ways of grabbing the images and forcing them into a zip to download.
我已经检查了如何执行此操作，但找不到任何抓取图像并将它们强制压缩为 zip 下载的好方法。

# define file array
$files = array(
'http://google.com/images/logo.png',
'http://upload.wikimedia.org/wikipedia/commons/thumb/5/53/Wikipedia-logo-en-big.png/220px-Wikipedia-logo-en-big.png',
);
# create new zip object
$zip = new ZipArchive();
# create a temp file & open it
$tmp_file = tempnam('.', '');
$zip->open($tmp_file, ZipArchive::CREATE);
# loop through each file
foreach ($files as $file) {
# download file
$download_file = file_get_contents($file);
#add it to the zip
$zip->addFromString(basename($file), $download_file);
}
# close zip
$zip->close();
# send the file to the browser as a download
header('Content-disposition: attachment; filename="my file.zip"');
header('Content-type: application/zip');
readfile($tmp_file);
unlink($tmp_file);
Note: This solution assumes you have allow_url_fopenenabled. Otherwise look into using cURL to download the file.
注意：此解决方案假定您已allow_url_fopen启用。否则考虑使用 cURL 下载文件。

I haven't tried this, but it seems like what you're looking for.
我没有试过这个，但它似乎是你正在寻找的。
<?php
$zip = new ZipArchive;
if ($zip->open('my_archive.zip') === TRUE) {
$zip->addFile($url, basename($url));
$zip->close();
echo 'ok';
} else {
echo 'failed';
}
?>
