Bagaimana [secara rekursif] Zip direktori di PHP?

Direktori itu seperti:

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

Saya menggunakan kelas PHP Zip yang sama yang digunakan di PHPMyAdmin http://trac.seagullproject.org/browser/branches/0.6-bugfix/lib/other/Zip.php . Saya tidak yakin bagaimana cara zip direktori daripada hanya sebuah file. Inilah yang saya miliki sejauh ini:

$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

tetapi ketika saya mencoba untuk mengekstrak file zip yang diunduh terkait, saya mendapatkan "operasi tidak diizinkan"

Kesalahan ini hanya terjadi ketika saya mencoba unzip di mac saya, ketika saya membuka zip melalui baris perintah file unzip ok. Apakah saya perlu mengirim jenis konten tertentu saat diunduh, saat ini 'application / zip'

Berikut adalah fungsi sederhana yang dapat memampatkan file atau direktori secara rekursif, hanya membutuhkan ekstensi zip yang akan dimuat.

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();
}

Sebut saja seperti ini:

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

Namun pengarsipan pohon direktori rekursif lainnya, diimplementasikan sebagai ekstensi ke ZipArchive. Sebagai bonus, fungsi pembantu kompresi pohon pernyataan tunggal disertakan. Nama lokal opsional didukung, seperti pada fungsi ZipArchive lainnya. Kesalahan menangani kode yang akan ditambahkan ...

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);

Saya telah mengedit jawaban Alix Axel untuk mengambil argumen ketiga, ketika mengatur argumen ketiga ini ke truesemua file akan ditambahkan di bawah direktori utama daripada langsung di folder zip.

Jika file zip ada, file tersebut akan dihapus juga.

Contoh:

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

Struktur truezip argrument ketiga :

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

Argrumen ketiga falseatau struktur zip hilang:

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

Kode yang diedit:

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();

Jika Ada Masalah Dengan Kode Beri Tahu Saya.

Saya perlu menjalankan fungsi Zip ini di Mac OSX

jadi saya akan selalu zip .DS_Store yang mengganggu itu.

Saya mengadaptasi https://stackoverflow.com/users/2019515/user2019515 dengan menyertakan file tambahanIgnore.

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 . '/'));

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

SO untuk mengabaikan .DS_Store dari zip, jalankan

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

Solusi hebat tetapi untuk Windows saya, saya perlu melakukan modifikasi. Di bawah kode modifikasi

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();
}

Kode ini berfungsi untuk windows dan 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 $source;
    }
}
else if (is_file($source) === true)
{
    $zip->addFromString(basename($source), file_get_contents($source));
}

return $zip->close();
}

Ini basis versi saya di Alix, berfungsi di Windows dan semoga di * nix juga:

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();
}

Berikut ini adalah fungsi rekursif sederhana, mudah dibaca yang bekerja dengan sangat baik:

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();

Mengikuti jawaban @ user2019515, saya perlu menangani pengecualian ke arsip saya. berikut adalah fungsi yang dihasilkan dengan sebuah contoh.

Fungsi Zip:

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();
}

Bagaimana cara menggunakannya :

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);
}
