如何在 PHP 中[递归地]压缩目录？

Question

目录类似于：

home/
    file1.html
    file2.html
Another_Dir/
    file8.html
    Sub_Dir/
        file19.html

我正在使用 PHPMyAdmin http://trac.seagullproject.org/browser/branches/0.6-bugfix/lib/other/Zip.php 。我不确定如何压缩目录而不仅仅是文件。这是我到目前为止所得到的：

$aFiles = $this->da->getDirTree($target);
/* $aFiles is something like, path => filetime
Array
(
    [home] => 
    [home/file1.html] => 1251280379
    [home/file2.html] => 1251280377
    etc...
)

*/
$zip = & new Zip();
foreach( $aFiles as $fileLocation => $time ){
    $file = $target . "/" . $fileLocation;
    if ( is_file($file) ){
        $buffer = file_get_contents($file);
        $zip->addFile($buffer, $fileLocation);
    }
}
THEN_SOME_PHP_CLASS::toDownloadData($zip); // this bit works ok

但是当我尝试解压缩相应的下载的 zip 文件时，我收到“不允许操作”

只有当我尝试在我的 mac 上解压缩时才会发生此错误，当我通过命令行解压缩时，文件解压正常。我是否需要在下载时发送特定的内容类型，目前为“application/zip”

Answer 1

这是一个简单的函数，可以递归压缩任何文件或目录，只需要加载 zip 扩展名。

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 . '/', '', $file . '/'));
            }
            else if (is_file($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();
}

像这样称呼它：

Zip('/folder/to/compress/', './compressed.zip');

Answer 2

另一种递归目录树归档，作为 ZipArchive 的扩展实现。作为奖励，还包括单语句树压缩辅助函数。与其他 ZipArchive 函数一样，支持可选的本地名称。待添加错误处理代码...

class ExtendedZip extends ZipArchive {

    // Member function to add a whole file system subtree to the archive
    public function addTree($dirname, $localname = '') {
        if ($localname)
            $this->addEmptyDir($localname);
        $this->_addTree($dirname, $localname);
    }

    // Internal function, to recurse
    protected function _addTree($dirname, $localname) {
        $dir = opendir($dirname);
        while ($filename = readdir($dir)) {
            // Discard . and ..
            if ($filename == '.' || $filename == '..')
                continue;

            // Proceed according to type
            $path = $dirname . '/' . $filename;
            $localpath = $localname ? ($localname . '/' . $filename) : $filename;
            if (is_dir($path)) {
                // Directory: add & recurse
                $this->addEmptyDir($localpath);
                $this->_addTree($path, $localpath);
            }
            else if (is_file($path)) {
                // File: just add
                $this->addFile($path, $localpath);
            }
        }
        closedir($dir);
    }

    // Helper function
    public static function zipTree($dirname, $zipFilename, $flags = 0, $localname = '') {
        $zip = new self();
        $zip->open($zipFilename, $flags);
        $zip->addTree($dirname, $localname);
        $zip->close();
    }
}

// Example
ExtendedZip::zipTree('/foo/bar', '/tmp/archive.zip', ZipArchive::CREATE);

Answer 3

当将第三个参数设置为 时，我编辑了 Alix Axel 的答案以采用第三个参数true 所有文件都将添加到主目录下，而不是直接添加到 zip 文件夹中。

如果 zip 文件存在，该文件也将被删除。

示例：

Zip('/path/to/maindirectory','/path/to/compressed.zip',true);

第三个参数 true zip 结构：

maindirectory
--- file 1
--- file 2
--- subdirectory 1
------ file 3
------ file 4
--- subdirectory 2
------ file 5
------ file 6

第三个参数 false 或缺少 zip 结构：

file 1
file 2
subdirectory 1
--- file 3
--- file 4
subdirectory 2
--- file 5
--- file 6

编辑后的代码：

function Zip($source, $destination, $include_dir = false)
{

    if (!extension_loaded('zip') || !file_exists($source)) {
        return false;
    }

    if (file_exists($destination)) {
        unlink ($destination);
    }

    $zip = new ZipArchive();
    if (!$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);

        if ($include_dir) {

            $arr = explode("/",$source);
            $maindir = $arr[count($arr)- 1];

            $source = "";
            for ($i=0; $i < count($arr) - 1; $i++) { 
                $source .= '/' . $arr[$i];
            }

            $source = substr($source, 1);

            $zip->addEmptyDir($maindir);

        }

        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 . '/', '', $file . '/'));
            }
            else if (is_file($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();
}

Answer 6

这是我的代码，用于 Zip 文件夹及其子文件夹及其文件，并使其可以 zip 格式下载，

function zip()
 {
$source='path/folder'// Path To the folder;
$destination='path/folder/abc.zip'// Path to the file and file name ; 
$include_dir = false;
$archive = 'abc.zip'// File Name ;

if (!extension_loaded('zip') || !file_exists($source)) {
    return false;
}

if (file_exists($destination)) {
    unlink ($destination);
}

$zip = new ZipArchive;

if (!$zip->open($archive, ZipArchive::CREATE)) {
    return false;
}
$source = str_replace('\\', '/', realpath($source));
if (is_dir($source) === true)
{

    $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);

    if ($include_dir) {

        $arr = explode("/",$source);
        $maindir = $arr[count($arr)- 1];

        $source = "";
        for ($i=0; $i < count($arr) - 1; $i++) { 
            $source .= '/' . $arr[$i];
        }

        $source = substr($source, 1);

        $zip->addEmptyDir($maindir);

    }

    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 . '/', '', $file . '/'));
        }
        else if (is_file($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));
}
$zip->close();

header('Content-Type: application/zip');
header('Content-disposition: attachment; filename='.$archive);
header('Content-Length: '.filesize($archive));
readfile($archive);
unlink($archive);
}

Answer 7

我需要在 Mac OSX 中运行这个 Zip 函数，

这样我总是会压缩那个烦人的 .DS_Store。

我通过包含额外的忽略文件来改编https://stackoverflow.com/users/2019515/user2019515。

function zipIt($source, $destination, $include_dir = false, $additionalIgnoreFiles = array())
{
    // Ignore "." and ".." folders by default
    $defaultIgnoreFiles = array('.', '..');

    // include more files to ignore
    $ignoreFiles = array_merge($defaultIgnoreFiles, $additionalIgnoreFiles);

    if (!extension_loaded('zip') || !file_exists($source)) {
        return false;
    }

    if (file_exists($destination)) {
        unlink ($destination);
    }

    $zip = new ZipArchive();
        if (!$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);

        if ($include_dir) {

            $arr = explode("/",$source);
            $maindir = $arr[count($arr)- 1];

            $source = "";
            for ($i=0; $i < count($arr) - 1; $i++) { 
                $source .= '/' . $arr[$i];
            }

            $source = substr($source, 1);

            $zip->addEmptyDir($maindir);

        }

        foreach ($files as $file)
        {
            $file = str_replace('\\', '/', $file);

            // purposely ignore files that are irrelevant
            if( in_array(substr($file, strrpos($file, '/')+1), $ignoreFiles) )
                continue;

            $file = realpath($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();
}

因此，要忽略 zip 中的 .DS_Store，请运行

zipIt('/path/to/folder', '/path/to/compressed.zip', false, array('.DS_Store'));

很好的解决方案，但对于我的 Windows，我需要进行修改。修改代码如下

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;

        if (is_dir($file) === true)
        {
            $zip->addEmptyDir(str_replace($source . '/', '', $file));
        }
        else if (is_file($file) === true)
        {

            $str1 = str_replace($source . '/', '', '/'.$file);
            $zip->addFromString($str1, file_get_contents($file));

        }
    }
}
else if (is_file($source) === true)
{
    $zip->addFromString(basename($source), file_get_contents($source));

此代码适用于 Windows 和 Linux。

function Zip($source, $destination)
{
if (!extension_loaded('zip') || !file_exists($source)) {
    return false;
}

$zip = new ZipArchive();
if (!$zip->open($destination, ZIPARCHIVE::CREATE)) {
    return false;
}

if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') {
    DEFINE('DS', DIRECTORY_SEPARATOR); //for windows
} else {
    DEFINE('DS', '/'); //for linux
}


$source = str_replace('\\', DS, realpath($source));

if (is_dir($source) === true)
{
    $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);
    echo $source;
    foreach ($files as $file)
    {
        $file = str_replace('\\',DS, $file);
        // Ignore "." and ".." folders
        if( in_array(substr($file, strrpos($file, DS)+1), array('.', '..')) )
            continue;

        $file = realpath($file);

        if (is_dir($file) === true)
        {
            $zip->addEmptyDir(str_replace($source . DS, '', $file . DS));
        }
        else if (is_file($file) === true)
        {
            $zip->addFromString(str_replace($source . DS, '', $file), file_get_contents($file));
        }
        echo $source;

这是我基于 Alix 的版本，适用于 Windows，希望也适用于 *nix：

function addFolderToZip($source, $destination, $flags = ZIPARCHIVE::OVERWRITE)
{
    $source = realpath($source);
    $destination = realpath($destination);

    if (!file_exists($source)) {
        die("file does not exist: " . $source);
    }

    $zip = new ZipArchive();
    if (!$zip->open($destination, $flags )) {
        die("Cannot open zip archive: " . $destination);
    }

    $files = new RecursiveIteratorIterator(
        new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);

    $sourceWithSeparator = $source . DIRECTORY_SEPARATOR;
    foreach ($files as $file)
    {
        // Ignore "." and ".." folders
        if(in_array(substr($file,strrpos($file, DIRECTORY_SEPARATOR)+1),array('.', '..')))
            continue;

        if (is_dir($file) === true)
        {
            $zip->addEmptyDir(
                str_replace($sourceWithSeparator, '', $file . DIRECTORY_SEPARATOR));

Answer 11

这是一个简单、易于阅读、运行良好的递归函数：

function zip_r($from, $zip, $base=false) {
    if (!file_exists($from) OR !extension_loaded('zip')) {return false;}
    if (!$base) {$base = $from;}
    $base = trim($base, '/');
    $zip->addEmptyDir($base);
    $dir = opendir($from);
    while (false !== ($file = readdir($dir))) {
        if ($file == '.' OR $file == '..') {continue;}

        if (is_dir($from . '/' . $file)) {
            zip_r($from . '/' . $file, $zip, $base . '/' . $file);
        } else {
            $zip->addFile($from . '/' . $file, $base . '/' . $file);
        }
    }
    return $zip;
}
$from = "/path/to/folder";
$base = "basezipfolder";
$zip = new ZipArchive();
$zip->open('zipfile.zip', ZIPARCHIVE::CREATE);
$zip = zip_r($from, $zip, $base);
$zip->close();

Zip 功能：

function Zip($source, $destination, $include_dir = false, $exclusions = false){
    // Remove existing archive
    if (file_exists($destination)) {
        unlink ($destination);
    }

    $zip = new ZipArchive();
    if (!$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);
        if ($include_dir) {
            $arr = explode("/",$source);
            $maindir = $arr[count($arr)- 1];
            $source = "";
            for ($i=0; $i < count($arr) - 1; $i++) {
                $source .= '/' . $arr[$i];
            }
            $source = substr($source, 1);
            $zip->addEmptyDir($maindir);
        }
        foreach ($files as $file){
            // Ignore "." and ".." folders
            $file = str_replace('\\', '/', $file);
            if(in_array(substr($file, strrpos($file, '/')+1), array('.', '..'))){
                continue;
            }

            // Add Exclusion
            if(($exclusions)&&(is_array($exclusions))){
                if(in_array(str_replace($source.'/', '', $file), $exclusions)){
                    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();
}

如何使用：

function backup(){
    $backup = 'tmp/backup-'.$this->site['version'].'.zip';
    $exclusions = [];
    // Excluding an entire directory
    $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator('tmp/'), RecursiveIteratorIterator::SELF_FIRST);
    foreach ($files as $file){
        array_push($exclusions,$file);
    }
    // Excluding a file
    array_push($exclusions,'config/config.php');
    // Excluding the backup file
    array_push($exclusions,$backup);
    $this->Zip('.',$backup, false, $exclusions);
}
