问题描述
I'm trying to backup my site by zipping it all, and putting the zip into an unnaccessible folder, done with PHP.
我正在尝试通过压缩所有内容来备份我的网站，并将 zip 放入一个无法访问的文件夹中，用 PHP 完成。 My code is我的代码是
<?php
Zip('../../', './');
function Zip($source, $destination)
{
if (extension_loaded('zip') === true)
{ echo'a';
if (file_exists($source) === true)
{
$zip = new ZipArchive();
if ($zip->open($destination, ZIPARCHIVE::CREATE) === true)
{
$source = realpath($source);
if (is_dir($source) === true)
{
$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);
foreach ($files as $file)
{
$file = realpath($file);
if (is_dir($file) === true)
{
$zip->addEmptyDir(str_replace($source . '/', '', $file . '/'));
}
else if (is_file($file) === true)
{
$zip->addFromString(str_replace($source . '/', '', $file), file_get_contents($file));
}
}
}
else if (is_file($source) === true)
{
$zip->addFromString(basename($source), file_get_contents($source));
}
}
return $zip->close(); // The error.
}
}
return false;
}
?>
But I get an error of Warning: ZipArchive::close() [ziparchive.close]: Invalid or unitialized Zip object in backup.php on line 41 I have searched google, and no results.但是我Warning: ZipArchive::close() [ziparchive.close]: Invalid or unitialized Zip object in backup.php on line 41收到错误Warning: ZipArchive::close() [ziparchive.close]: Invalid or unitialized Zip object in backup.php on line 41我搜索了谷歌，但没有结果。

In my case the destination folder was completely missing and this was causing the error on close() .在我的情况下，目标文件夹完全丢失，这导致了close()错误。
Therefore I check if the destination folder exists and, if not, I try to create it.因此，我检查目标文件夹是否存在，如果不存在，则尝试创建它。 If both calls fail, I throw an exception.如果两个调用都失败，我会抛出异常。 In your case would be something like the following:在您的情况下，将类似于以下内容：
$destinationPath = (new \SplFileInfo($destination))->getPath();
if (!is_dir($destinationPath) && !mkdir($destinationPath, 0755, true)) {
throw new \Exception(sprintf('Destination folder "%s" is missing and cannot be created', $destinationPath));
}
