어떻게 [재귀 적으로] PHP에서 디렉토리를 압축합니까?

디렉토리는 다음과 같습니다.

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

PHPMyAdmin http://trac.seagullproject.org/browser/branches/0.6-bugfix/lib/other/Zip.php 에서 사용되는 것과 동일한 PHP Zip 클래스를 사용하고 있습니다. 파일이 아닌 디렉토리를 압축하는 방법을 잘 모르겠습니다. 지금까지 내가 가진 내용은 다음과 같습니다.

$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

하지만 다운로드 한 해당 zip 파일의 압축을 풀려고하면 "작업이 허용되지 않음"이 표시됩니다.

이 오류는 Mac에서 압축을 풀려고 할 때만 발생하며 명령 줄을 통해 압축을 풀면 파일이 정상적으로 압축 해제됩니다. 다운로드시 특정 콘텐츠 유형 (현재 'application / zip')을 보내야합니까?

다음은 모든 파일 또는 디렉토리를 재귀 적으로 압축 할 수있는 간단한 함수입니다. zip 확장자 만로드하면됩니다.

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();
}

다음과 같이 호출하십시오.

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

또 다른 재귀 디렉토리 트리 아카이브는 ZipArchive의 확장으로 구현됩니다. 보너스로 단일 문 트리 압축 도우미 기능이 포함되어 있습니다. 다른 ZipArchive 함수에서와 같이 선택적 localname이 지원됩니다. 추가 할 오류 처리 코드 ...

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);

세 번째 인수를 취하도록 Alix Axel 의 답변을 편집했습니다. 이 세 번째 인수를 true모든 파일에 설정하면 zip 폴더가 아닌 기본 디렉토리 아래에 추가됩니다.

zip 파일이 존재하면 파일도 삭제됩니다.

예:

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

세 번째 인수 truezip 구조 :

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

세 번째 인수 false또는 누락 된 zip 구조 :

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

수정 된 코드 :

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

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

    if (file_exists($destination)) {

    {

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

        if ($include_dir) {

            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);

Mac OSX에서이 Zip 기능을 실행해야했습니다.

그래서 나는 항상 성가신 .DS_Store를 압축합니다.

추가 무시 파일을 포함하여 https://stackoverflow.com/users/2019515/user2019515 를 수정 했습니다.

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();
}

따라서 zip에서 .DS_Store를 무시하려면 다음을 실행하십시오.

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

훌륭한 솔루션이지만 Windows의 경우 수정이 필요합니다. 수정 코드 아래

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));
}

return $zip->close();
}

이 코드는 Windows와 Linux 모두에서 작동합니다.

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

return $zip->close();
}

다음은 Alix의 버전 기반이며 Windows에서 작동하며 * nix에서도 작동합니다.

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, '', $file . DIRECTORY_SEPARATOR));
        }
        else if (is_file($file) === true)
        {
            $zip->addFile($file, str_replace($sourceWithSeparator, '', $file));
        }
    }

    return $zip->close();
}

다음은 매우 잘 작동하는 간단하고 읽기 쉬운 재귀 함수입니다.

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);

@ user2019515 답변에 따라 아카이브에 대한 제외를 처리해야했습니다. 여기에 예제가있는 결과 함수가 있습니다.

우편 기능 :

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();
}

사용 방법 :

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);
}
