我在stackoveflow找到了一些关于如何压缩特定文件的代码，但是特定文件夹怎么样？
Folder/
index.html
picture.jpg
important.txt
在My Folder里面，有文件。压缩My Folder后，我还要删除除important.txt以外的文件夹的全部内容。
我需要你的帮助。 感谢。

// 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

$files = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($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

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::OVERWRITE))
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();

试试这个：
$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();
此不会递归拉链。

我认为这是在zip应用程序位于搜索路径中的服务器上运行的。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。
exec('zip -r archive.zip "My folder"');
unlink('My\ folder/index.html');
unlink('My\ folder/picture.jpg');
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。

我尝试使用下面的代码，它正在运行。代码是自解释的，如果您有任何问题，请告诉我。
<?php

$this->addDirDo($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)

这是一个将整个文件夹及其内容压缩为zip文件的功能，你可以像这样简单地使用它：
addzip ("path/folder/" , "/path2/folder.zip" );
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";
}

为什么不尝试 EFS PhP-ZiP MultiVolume脚本 ...我压缩并传输了数百个演出和数百万个文件...需要ssh才能有效地创建档案。
但我相信结果文件可以直接从php使用exec：
exec('zip -r backup-2013-03-30_0 . -i@backup-2013-03-30_0.txt');
我不知道它是否有效。我没试过......
“秘密”是归档的执行时间不应超过执行PHP代码所允许的时间。

这是用PHP制作ZIP的一个工作示例：
$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();

使用此功能：
function zip($source, $destination)
{
if (!extension_loaded('zip') || !file_exists($source)) {
return false;
}
$zip = new ZipArchive();
if (!$zip->open($destination, ZIPARCHIVE::CREATE)) {
return false;
}
$source = str_replace('\\', '/', realpath($source));
if (is_dir($source) === true) {
$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);
foreach ($files as $file) {
$file = str_replace('\\', '/', $file);
// Ignore "." and ".." folders
if (in_array(substr($file, strrpos($file, '/')+1), array('.', '..'))) {
continue;
}
$file = realpath($file);
if (is_dir($file) === true) {
$zip->addEmptyDir(str_replace($source . '/', '', $file . '/'));
} elseif (is_file($file) === true) {
$zip->addFromString(str_replace($source . '/', '', $file), file_get_contents($file));
}
}
} elseif (is_file($source) === true) {
$zip->addFromString(basename($source), file_get_contents($source));
}
return $zip->close();
}
使用示例：
zip('/folder/to/compress/', './compressed.zip');

使用此功能正常。

我在谷歌发现这篇文章是第二个最高结果，首先是使用exec :(
无论如何，虽然这并不完全符合我的需求..我决定用其快速但扩展的版本为其他人发布答案。
脚本功能
无论如何，在脚本上..虽然它可能看起来很多..请记住这里有多余的..所以随时删除报告部分...
它也可能看起来很乱，某些东西可以轻松清理......所以不要评论它，它只是一个快速的脚本，基本的评论投入..不是为了实际使用..但易于清理用于实际使用！
在这个例子中，它是从根目录www / public_html文件夹中的目录运行的。所以只需要向上移动一个文件夹即可到达根目录。

它做了什么？
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。它可以对以前的备份进行简单检测并跳过它们。
CRON BACKUP
这个脚本我刚刚在linux上测试过，并且通过使用pathBase的绝对URL来完成cron作业。

// Initialize archive object

$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($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 archive will be created only after closing object
$zip->close();
