open - ¿Cómo[recursivamente] Zip un directorio en PHP?

un zip php

Question

El directorio es algo así como:

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

Estoy usando la misma clase de PHP Zip utilizada en PHPMyAdmin http://trac.seagullproject.org/browser/branches/0.6-bugfix/lib/other/Zip.php . No estoy seguro de cómo comprimir un directorio en lugar de solo un archivo. Esto es lo que tengo hasta ahora:

$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

pero cuando intento descomprimir el archivo zip descargado correspondiente obtengo "operación no permitida"

Este error solo ocurre cuando intento descomprimir en mi mac, cuando descomprimo a través de la línea de comando el archivo se descomprime bien. ¿Debo enviar un tipo de contenido específico en la descarga, actualmente ''aplicación / zip''?

Answer 1

Aquí está la función recursiva simple, fácil de leer que funciona muy bien:

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();

Aquí está mi código para comprimir las carpetas y sus subcarpetas y sus archivos y hacer que se pueda descargar en formato zip

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);
}

Si surge un problema con el código, hágamelo saber.

Answer 3

Aquí está mi versión base en Alix, funciona en Windows y con suerte en * nix también:

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();
}

Answer 4

Aquí hay una función simple que puede comprimir cualquier archivo o directorio recursivamente, solo necesita la extensión zip para ser cargada.

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();
}

Llámalo así:

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

Answer 5

Este código funciona tanto para Windows como para 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();
}

Answer 6

Gran solución, pero para mi Windows necesito hacer modificaciones. Debajo del código de modificación

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();
}

Answer 7

He editado la respuesta de para tomar un tercer texto, cuando establezco este tercer argumento como true todos los archivos se agregarán en el directorio principal en lugar de directamente en la carpeta zip.

Si el archivo zip existe, el archivo también se eliminará.

Ejemplo:

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

Tercer argrumento con true estructura zip:

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

Tercer argrumento estructura postal false o faltante:

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

Código editado:

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));

Answer 8

Necesitaba ejecutar esta función Zip en Mac OSX

así que siempre comprimiría esa molesta .DS_Store.

He adaptado incluyendo archivos adicionales de Ignore.

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();
}

SO para ignorar .DS_Store de zip, ejecutas

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

Answer 9

Otro archivo de árbol de directorios recursivo más, implementado como una extensión de ZipArchive. Como beneficio adicional, se incluye una función auxiliar de compresión de árbol de declaración única. El nombre local opcional es compatible, como en otras funciones de ZipArchive. Error al manejar el código que se agregará ...

class ExtendedZip extends ZipArchive {

    // Member function to add a whole file system subtree to the archive
    public function addTree($dirname, $localname = '''') {

            // 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);

        $zip->open($zipFilename, $flags);
        $zip->addTree($dirname, $localname);
