Php add file to zip

ZIP в PHP (ZipArchive)

Класс ZipArchive позволяет быстро и удобно работать с ZIP-архивам, рассмотрим основные возможности класса.

Добавление файлов в архив

В примере используются константы:

• ZipArchive::CREATE – создавать архив, если он не существует
• ZipArchive::OVERWRITE – если архив существует, то игнорировать текущее его содержимое т.е. работать как с пустым архивом.

$zip = new ZipArchive(); $zip->open(__DIR__ . '/archive.zip', ZipArchive::CREATE|ZipArchive::OVERWRITE); $zip->addFile(__DIR__ . '/image1.jpg', 'image1.jpg'); $zip->addFile(__DIR__ . '/image2.jpg', 'image2.jpg'); $zip->close();

Если файл необходимо поместить в директорию, то предварительно не нужно создавать пустую папку. Можно просто указать путь и имя файла, например «src»:

$zip->addFile(__DIR__ . '/image1.jpg', 'src/image1.jpg'); $zip->addFile(__DIR__ . '/image2.jpg', 'src/image2.jpg');

Если текстовой файл генерится прямо в скрипте, то удобней скинуть его в архив методом addFromString() .

$contents = 'Содержание файла file.log'; $zip = new ZipArchive(); $zip->open(__DIR__ . '/archive.zip', ZipArchive::CREATE|ZipArchive::OVERWRITE); $zip->addFromString('file.log', $contents); $zip->close();

Заархивировать директорию с содержимым

Сделать архив сайта можно с помощью рекурсивной функции, функция обойдет все файлы в директориях и добавит их в архив.

function addFileRecursion($zip, $dir, $start = '') < if (empty($start)) < $start = $dir; >if ($objs = glob($dir . '/*')) < foreach($objs as $obj) < if (is_dir($obj)) < addFileRecursion($zip, $obj, $start); >else < $zip->addFile($obj, str_replace(dirname($start) . '/', '', $obj)); > > > > $zip = new ZipArchive(); $zip->open(__DIR__ . '/archive.zip', ZipArchive::CREATE|ZipArchive::OVERWRITE); addFileRecursion($zip, __DIR__ . '/test'); $zip->close();

Переименовать файл

$zip = new ZipArchive(); $zip->open(__DIR__ . '/archive.zip'); $zip->renameName('image2.jpg', 'images.jpg'); $zip->close();

Если файл лежит в папке

$zip->renameName('src/image2.jpg', 'src/images.jpg');

Удалить файл из архива

$zip = new ZipArchive(); $zip->open(__DIR__ . '/archive.zip'); $zip->deleteName('image2.jpg'); $zip->close();

Если файл лежит в папке

$zip->deleteName('src/image2.jpg');

Список файлов в архиве

$zip = new ZipArchive(); $zip->open(__DIR__ . '/archive.zip'); $i = 0; $list = array(); while($name = $zip->getNameIndex($i)) < $list[$i] = $name; $i++; >print_r($list); $zip->close();

Array ( [0] => src/image1.jpg [1] => src/image2.jpg [2] => file.log )

Извлечь весь архив

$zip = new ZipArchive(); $zip->open(__DIR__ . '/archive.zip'); $zip->extractTo(__DIR__); $zip->close();

Извлечь определенные файлы

$zip = new ZipArchive(); $zip->open(__DIR__ . '/archive.zip'); $zip->extractTo(__DIR__, array('src/image1.jpg', 'src/image2.jpg')); $zip->close();

Извлечь файл в поток

Данный метод удобен если требуется только прочитать содержимое файла.

$zip = new ZipArchive(); $zip->open(__DIR__ . '/archive.zip'); $contents = ''; $fp = $zip->getStream('file.log'); while (!feof($fp)) < $contents .= fread($fp, 2); >fclose($fp); echo $contents; $zip->close();

Add Files & Folders In PHP ZIP (Basics, Entire Folder, Recursive)

Welcome to a quick tutorial on how to add files and folders with PHP Zip. So you have a project that needs some zip archive action, and no idea where to start?

We can add files and folders to a zip file in PHP using the ZipArchive extension:

• $zip = new ZipArchive();
• $zip->open(«archive.zip», ZipArchive::CREATE);
• $zip->addFile(«target.file», «name-in-zip.file»);
• $zip->addEmptyDir(«folder»);
• $zip->close();

That should cover the basics, but adding entire folders is a different story – Read on for more examples!

TLDR – QUICK SLIDES

HOW TO ADD FILES & FOLDERS WITH PHP ZIP

All right, let us now get into the examples of the various ways to add files and folders into a zip archive in PHP.

1) BASICS – ADDING FILES & FOLDERS

open($zipfile, ZipArchive::CREATE) === true) < // (B1) ADD FILE echo $zip->addFile("readme.txt", "filename-in-zip.txt") ? "File added to zip archive" : "Error adding file to zip archive" ; // (B2) ADD FOLDER echo $zip->addEmptyDir("folder") ? "Folder added to zip archive" : "Error adding folder to zip archive" ; // (B3) CLOSE ZIP echo $zip->close() ? "Zip archive closed" : "Error closing zip archive" ; > // (C) FAILED TO OPEN/CREATE ZIP FILE else < echo "Failed to open/create $zipfile"; >

Yes, this is kind of an “expanded version” of the introduction – We start by creating a $zip = new ZipArchive() object, then there are only 4 basic zip functions that you should know.

• open(FILE, MODE) This opens a zip file, but take extra note of the possible modes:
  • ZipArchive::CREATE – Creates a new zip archive if not found.
  • ZipArchive::OVERWRITE – Overwrite if there is an existing zip archive.
  • ZipArchive::EXCL – The safer way, which will return an error if there is an existing zip archive.
  • ZipArchive::RDONLY – Readonly.
  • ZipArchive::CHECKONS – Checks the zip archive, throws an error if the checksum fails.

  2) APPENDING FILES INTO A FOLDER IN THE ZIP ARCHIVE

  open($zipfile, ZipArchive::CREATE) === true) < // (B) APPEND FILE INTO ZIP echo $zip->addFile("1-basic.php", "1-basic.php") ? "File added to zip archive" : "Error adding file to zip archive" ; // (C) ADD FILE INTO FOLDER IN ZIP echo $zip->addFile("2-append.php", "folder/2-append.php") ? "File added to zip archive" : "Error adding file to zip archive" ; // (D) CLOSE ZIP echo $zip->close() ? "Zip archive closed" : "Error closing zip archive" ; > // (E) FAILED TO OPEN/CREATE ZIP FILE else < echo "Failed to open/create $zipfile"; >

  To append more files into an existing zip archive, we simply open it again and use the addFile() function; To add the file into a folder within the zip archive, we only have to specify it accordingly – addFile(TARGET.FILE, FOLDER-IN-ZIP/SAVE.FILE) .

  3) FROM STRING TO ZIP FILE

  open($zipfile, ZipArchive::CREATE) === true) < // (B) ADD FROM STRING echo $zip->addFromString("string.txt", "This is a string!") ? "File added to zip archive" : "Error adding file to zip archive" ; > // (C) FAILED TO OPEN/CREATE ZIP FILE else < echo "Failed to open/create $zipfile"; >

  Just a convenience for you guys who want to archive logs or any content – Use the addFromString() function to save a string into a zip file.

  4) ADD ENTIRE FOLDER INTO ZIP ARCHIVE (USING GLOB)

  open($zipfile, ZipArchive::CREATE) === true) < // (B1) ADD ENTIRE FOLDER // add all jpg png gif files in "/test/" into the "inside/" folder of the zip archive echo $zip->addGlob($tozip . "*.", GLOB_BRACE, [ "add_path" => "inside/", "remove_all_path" => true ]) ? "Folder added to zip" : "Error adding folder to zip" ; // (B2) CLOSE ZIP echo $zip->close() ? "Zip archive closed" : "Error closing zip archive" ; > // (C) FAILED TO OPEN/CREATE ZIP FILE else < echo "Failed to open/create $zipfile"; >

  PHP comes with a very handy glob() function to filter out files/folders in the system. There is also a addGlob() function that we can use in the zip archive – To add an entire folder or filter out certain file extensions only.

  Take note though – This will not “dig” into the sub-folders of the specified target folder.

  5) ADD ENTIRE FOLDER INTO ZIP ARCHIVE (USING PATTERN)

  open($zipfile, ZipArchive::CREATE) === true) < // (B1) ADD ENTIRE FOLDER // add all php txt files in "/test/" into the "inside/" folder of the zip archive echo $zip->addPattern("/\.(?:php|txt)$/", $tozip, [ "add_path" => "inside/", "remove_all_path" => true ]) ? "Folder added to zip" : "Error adding folder to zip" ; // (B2) CLOSE ZIP echo $zip->close() ? "Zip archive closed" : "Error closing zip archive" ; > // (C) FAILED TO OPEN/CREATE ZIP FILE else < echo "Failed to open/create $zipfile"; >

  This is an alternative to addGlob() , addPattern() uses the “standard regular expression” to filter out files. But take note again, this will not drill into the sub-folders.

  6) RECURSIVELY ADD FOLDER AND SUB-FOLDERS

  open($zipfile, ZipArchive::OVERWRITE | ZipArchive::CREATE) === true) < // (B1) RECURSIVE ADD function zipall ($folder, $base, $ziparchive) < // FOLDER NAME INSIDE ZIP $options = ["remove_all_path" =>true]; if ($folder != $base) < $options["add_path"] = substr($folder, strlen($base)); >// ADD CURRENT FOLDER TO ZIP ARCHIVE echo $ziparchive->addGlob($folder."*.", GLOB_BRACE, $options) ? "Folder added to zip" : "Error adding folder to zip" ; // ADD FOLDERS IN FOLDER $folders = glob($folder . "*", GLOB_ONLYDIR); if (count($folders)!=0) < foreach ($folders as $f) < zipall($f."/", $base, $ziparchive); >> > zipall($tozip, $tozip, $zip); // (B2) CLOSE ZIP echo $zip->close() ? "Zip archive closed" : "Error closing zip archive" ; > // (C) FAILED TO OPEN/CREATE ZIP FILE else < echo "Failed to open/create $zipfile"; >

  Finally, this is sadly the way to zip an entire folder, along with the sub-folders inside… Not going to explain this line-by-line, but essentially, use a recursive function to drill into the sub-folders themselves.
