Zip a whole folder:
压缩整个文件夹：
// Get real path for our folder
$rootPath = realpath('folder-to-zip');
// Initialize archive object
$zip = new ZipArchive();
$zip->open('file.zip', ZipArchive::CREATE | ZipArchive::OVERWRITE);
// Create recursive directory iterator
/** @var SplFileInfo[] $files */
$files = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($rootPath),
RecursiveIteratorIterator::LEAVES_ONLY
);
foreach ($files as $name => $file)
{
// Skip directories (they would be added automatically)
if (!$file->isDir())
{
// Get real and relative path for current file
$filePath = $file->getRealPath();
$relativePath = substr($filePath, strlen($rootPath) + 1);
// Add current file to archive
$zip->addFile($filePath, $relativePath);
}
}
// Zip archive will be created only after closing object
$zip->close();
Zip a whole folder + delete all files except "important.txt":
压缩整个文件夹 + 删除除“important.txt”之外的所有文件：
// Get real path for our folder
$rootPath = realpath('folder-to-zip');
// Initialize archive object
$zip = new ZipArchive();
$zip->open('file.zip', ZipArchive::CREATE | ZipArchive::OVERWRITE);
// Initialize empty "delete list"
$filesToDelete = array();
// Create recursive directory iterator
/** @var SplFileInfo[] $files */
$files = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($rootPath),
RecursiveIteratorIterator::LEAVES_ONLY
);
foreach ($files as $name => $file)
{
// Skip directories (they would be added automatically)
if (!$file->isDir())
{
// Get real and relative path for current file
$filePath = $file->getRealPath();
$relativePath = substr($filePath, strlen($rootPath) + 1);
// Add current file to archive
$zip->addFile($filePath, $relativePath);
// Add current file to "delete list"
// delete it later cause ZipArchive create archive only after calling close function and ZipArchive lock files until archive created)
if ($file->getFilename() != 'important.txt')
{
$filesToDelete[] = $filePath;
}
}
}
// Zip archive will be created only after closing object
$zip->close();
// Delete all files from "delete list"
foreach ($filesToDelete as $file)
{
unlink($file);
}

There is a useful undocumented method in the ZipArchive class: addGlob();
ZipArchive 类中有一个有用的未记录方法：addGlob();
$zipFile = "./testZip.zip";
$zipArchive = new ZipArchive();
if ($zipArchive->open($zipFile, (ZipArchive::CREATE | ZipArchive::OVERWRITE)) !== true)
die("Failed to create archive\n");
$zipArchive->addGlob("./*.txt");
if ($zipArchive->status != ZIPARCHIVE::ER_OK)
echo "Failed to write files to zip\n";
$zipArchive->close();
Now documented at: www.php.net/manual/en/ziparchive.addglob.php

Try this:
尝试这个：
$zip = new ZipArchive;
$zip->open('myzip.zip', ZipArchive::CREATE);
foreach (glob("target_folder/*") as $file) {
$zip->addFile($file);
if ($file != 'target_folder/important.txt') unlink($file);
}
$zip->close();
This will notzip recursively though.
但这不会递归压缩。

I assume this is running on a server where the zip application is in the search path. Should be true for all unix-based and I guess most windows-based servers.
我假设这是在 zip 应用程序位于搜索路径中的服务器上运行。应该适用于所有基于 Unix 的服务器，我猜大多数基于 Windows 的服务器都是如此。
exec('zip -r archive.zip "My folder"');
unlink('My\ folder/index.html');
unlink('My\ folder/picture.jpg');
The archive will reside in archive.zip afterwards. Keep in mind that blanks in file or folder names are a common cause of errors and should be avoided where possible.
之后存档将驻留在 archive.zip 中。请记住，文件或文件夹名称中的空格是导致错误的常见原因，应尽可能避免。

I tried with the code below and it is working. The code is self explanatory, please let me know if you have any questions.
我尝试使用下面的代码，它正在工作。代码是不言自明的，如果您有任何问题，请告诉我。
<?php
class FlxZipArchive extends ZipArchive
{
public function addDir($location, $name)
{
$this->addEmptyDir($name);
$this->addDirDo($location, $name);
}
private function addDirDo($location, $name)
{
$name .= '/';
$location .= '/';
$dir = opendir ($location);
while ($file = readdir($dir))
{
if ($file == '.' || $file == '..') continue;
$do = (filetype( $location . $file) == 'dir') ? 'addDir' : 'addFile';
$this->$do($location . $file, $name . $file);
}
}
}
?>
<?php
$the_folder = '/path/to/folder/to/be/zipped';
$zip_file_name = '/path/to/zip/archive.zip';
$za = new FlxZipArchive;
$res = $za->open($zip_file_name, ZipArchive::CREATE);
if($res === TRUE)
{
$za->addDir($the_folder, basename($the_folder));
$za->close();
}
else{
echo 'Could not create a zip archive';
}
?>

This is a function that zips a whole folder and its contents in to a zip file and you can use it simple like this :
这是一个将整个文件夹及其内容压缩到一个 zip 文件中的功能，您可以像这样简单地使用它：
addzip ("path/folder/" , "/path2/folder.zip" );
function :
功能 ：
// compress all files in the source directory to destination directory
function create_zip($files = array(), $dest = '', $overwrite = false) {
if (file_exists($dest) && !$overwrite) {
return false;
}
if (($files)) {
$zip = new ZipArchive();
if ($zip->open($dest, $overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE) !== true) {
return false;
}
foreach ($files as $file) {
$zip->addFile($file, $file);
}
$zip->close();
return file_exists($dest);
} else {
return false;
}
}
function addzip($source, $destination) {
$files_to_zip = glob($source . '/*');
create_zip($files_to_zip, $destination);
echo "done";
}

Why not Try EFS PhP-ZiP MultiVolume Script... I zipped and transferred hundreds of gigs and millions of files ... ssh is needed to effectively create archives.
为什么不试试EFS PhP-ZiP MultiVolume Script......我压缩并传输了数百个演出和数百万个文件......需要 ssh 来有效地创建档案。
But i belive that resulting files can be used with exec directly from php:
但我相信生成的文件可以直接从 php 与 exec 一起使用：
exec('zip -r backup-2013-03-30_0 . -i@backup-2013-03-30_0.txt');
I do not know if it works. I have not tried ...
我不知道它是否有效。我没试过...
"the secret" is that the execution time for archiving should not exceed the time allowed for execution of PHP code.
“秘诀”是归档的执行时间不应超过 PHP 代码允许执行的时间。

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));---This is main function
}
else{
echo"file does not exist";
}
}
$zip->close();

I found this post in google as the second top result, first was using exec :(
我在谷歌中发现这篇文章是第二个顶级结果，首先是使用 exec :(
Anyway, while this did not suite my needs exactly.. I decided to post an answer for others with my quick but extended version of this.
无论如何，虽然这并不完全符合我的需求......我决定用我的快速但扩展版本为其他人发布答案。
SCRIPT FEATURES
脚本特性
- Backup file naming day by day, PREFIX-YYYY-MM-DD-POSTFIX.EXTENSION
- File Reporting / Missing
- Previous Backups Listing
- Does not zip / include previous backups ;)
- Works on windows/linux
- 备份文件逐日命名，PREFIX-YYYY-MM-DD-POSTFIX.EXTENSION
- 文件报告/丢失
- 以前的备份列表
- 不压缩/包括以前的备份;)
- 适用于 Windows/Linux
Anyway, onto the script.. While it may look like a lot.. Remember there is excess in here.. So feel free to delete the reporting sections as needed...
无论如何，到脚本上.. 虽然它可能看起来很多.. 请记住这里有多余的.. 所以请根据需要随意删除报告部分......
Also it may look messy as well and certain things could be cleaned up easily... So dont comment about it, its just a quick script with basic comments thrown in.. NOT FOR LIVE USE.. But easy to clean up for live use!
它也可能看起来很乱，某些东西可以很容易地清理......所以不要评论它，它只是一个带有基本评论的快速脚本......不适合实时使用......但易于清理以供实时使用！
In this example, it is run from a directory that is inside of the root www / public_html folder.. So only needs to travel up one folder to get to the root.
在这个例子中，它是从根 www/public_html 文件夹内的一个目录运行的。所以只需要向上移动一个文件夹即可到达根目录。

WHAT DOES IT DO??
它有什么作用？？
It will simply zip the complete contents of the variable $pathBase and store the zip in that same folder. It does a simple detection for previous backups and skips them.
它将简单地压缩变量 $pathBase 的完整内容并将 zip 存储在同一文件夹中。它对以前的备份进行简单的检测并跳过它们。
CRON BACKUP
定时备份
This script i've just tested on linux and worked fine from a cron job with using an absolute url for the pathBase.
这个脚本我刚刚在 linux 上测试过，并且在使用 pathBase 的绝对 url 的 cron 作业中运行良好。

Use this function:
使用这个功能：
