Note

I haven't updated this package in a long time except merging PRs. The last time I was using this package was with PHP5. I archived the repository for the reason that I am no longer working with PHP (we all have to move on sometimes) and have no time to take proper care of it anymore.

Feel free to read the code, to fork it or to use it in whatever way you want.

Zipper

This is a simple Wrapper around the ZipArchive methods with some handy functions.

Installation

1. Add this package to the list of required packages, inside composer.json

• for Laravel 5: "chumper/zipper": "1.0.x"
• for Laravel 4: "chumper/zipper": "0.5.x"

2. Run composer update

3. Go to app/config/app.php

• add to providers Chumper\Zipper\ZipperServiceProvider::class
• add to aliases 'Zipper' => Chumper\Zipper\Zipper::class

You can now access Zipper with the Zipper alias.

Simple example

$files = glob('public/files/*');
Zipper::make('public/test.zip')->add($files)->close();

• by default the package will create the test.zip in the project route folder but in the example above we changed it to project_route/public/.

Another example

$zipper = new \Chumper\Zipper\Zipper;
$zipper->make('test.zip')->folder('test')->add('composer.json');
$zipper->zip('test.zip')->folder('test')->add('composer.json','test');
$zipper->remove('composer.lock');
$zipper->folder('mySuperPackage')->add(
array(
'vendor',
'composer.json'
),
);
$zipper->getFileContent('mySuperPackage/composer.json');
$zipper->make('test.zip')->extractTo('',array('mySuperPackage/composer.json'),Zipper::WHITELIST);
$zipper->close();

Note: Please be aware that you need to call ->close() at the end to write the zip file to disk.

You can easily chain most functions, except getFileContent, getStatus, close and extractTo which must come at the end of the chain.

The main reason I wrote this little package is the extractTo method since it allows you to be very flexible when extracting zips. So you can for example implement an update method which will just override the changed files.

Functions

make($pathToFile)

Create or Open a zip archive; if the file does not exists it will create a new one. It will return the Zipper instance so you can chain easily.

add($files/folder)

You can add an array of Files, or a Folder and all the files in that folder will then be added, so from the first example we could instead do something like $files = 'public/files/';.

addString($filename, $content)

add a single file to the zip by specifying a name and the content as strings.

remove($file/s)

removes a single file or an array of files from the zip.

folder($folder)

Specify a folder to 'add files to' or 'remove files from' from the zip, example

Zipper::make('test.zip')->folder('test')->add('composer.json');
Zipper::make('test.zip')->folder('test')->remove('composer.json');

listFiles($regexFilter = null)

Lists all files within archive (if no filter pattern is provided). Use $regexFilter parameter to filter files. See Pattern Syntax for regular expression syntax

NB: listFiles ignores folder set with folder function

Example: Return all files/folders ending/not ending with '.log' pattern (case insensitive). This will return matches in sub folders and their sub folders also

$logFiles = Zipper::make('test.zip')->listFiles('/\.log$/i'); $notLogFiles = Zipper::make('test.zip')->listFiles('/^(?!.*\.log).*$/i'); 

home()

Resets the folder pointer.

zip($fileName)

Uses the ZipRepository for file handling.

getFileContent($filePath)

get the content of a file in the zip. This will return the content or false.

getStatus()

get the opening status of the zip as integer.

close()

closes the zip and writes all changes.

extractTo($path)

Extracts the content of the zip archive to the specified location, for example

Zipper::make('test.zip')->folder('test')->extractTo('foo');

This will go into the folder test in the zip file and extract the content of that folder only to the folder foo, this is equal to using the Zipper::WHITELIST.

This command is really nice to get just a part of the zip file, you can also pass a 2nd & 3rd param to specify a single or an array of files that will be

NB: Php ZipArchive uses internally '/' as directory separator for files/folders in zip. So Windows users should not set whitelist/blacklist patterns with '' as it will not match anything

white listed

Zipper::WHITELIST

Zipper::make('test.zip')->extractTo('public', array('vendor'), Zipper::WHITELIST);

Which will extract the test.zip into the public folder but only files/folders starting with vendor prefix inside the zip will be extracted.

or black listed

Zipper::BLACKLIST Which will extract the test.zip into the public folder except files/folders starting with vendor prefix inside the zip will not be extracted.

Zipper::make('test.zip')->extractTo('public', array('vendor'), Zipper::BLACKLIST);

Zipper::EXACT_MATCH

Zipper::make('test.zip')
->folder('vendor')
->extractTo('public', array('composer', 'bin/phpunit'), Zipper::WHITELIST | Zipper::EXACT_MATCH);

Which will extract the test.zip into the public folder but only files/folders exact matching names. So this will:

• extract file or folder named composer in folder named vendor inside zip to public resulting public/composer
• extract file or folder named bin/phpunit in vendor/bin/phpunit folder inside zip to public resulting public/bin/phpunit

NB: extracting files/folder from zip without setting Zipper::EXACT_MATCH When zip has similar structure as below and only test.bat is given as whitelist/blacklist argument then extractTo would extract all those files and folders as they all start with given string

test.zip
|- test.bat
|- test.bat.~
|- test.bat.dir/
|- fileInSubFolder.log

extractMatchingRegex($path, $regex)

Extracts the content of the zip archive matching regular expression to the specified location. See Pattern Syntax for regular expression syntax.

Example: extract all files ending with .php from src folder and its sub folders.

Zipper::make('test.zip')->folder('src')->extractMatchingRegex($path, '/\.php$/i'); 

Example: extract all files except those ending with test.php from src folder and its sub folders.

Zipper::make('test.zip')->folder('src')->extractMatchingRegex($path, '/^(?!.*test\.php).*$/i'); 

Development

Maybe it is a good idea to add other compression functions like rar, phar or bzip2 etc... Everything is setup for that, if you want just fork and develop further.

If you need other functions or got errors, please leave an issue on github.
