Usage

Read files from an archive:

foreach (new Tar\FileReader('example.tar') as $file) {
    echo "File {$file->getName()} is {$file->getSize()} bytes size, content of file:\n";
    echo $fileInfo->getContent() . "\n";
}

Package recognizes few types of Archive when using classic filename extension (e.g.: .tar, .tgz, .tar.bz2), but You can explicitly define archive type thought second parameter:

use JakubBoucek\Tar;

foreach (new Tar\FileReader('example.tar+gzip', new Tar\Filehandler\Gzip()) as $file) {
    echo "File {$file->getName()} is {$file->getSize()} bytes size.\n";
}

Package allows to process any type of stream, use StreamReader instead of FileReader:

use JakubBoucek\Tar;

$stream = someBeatifulFuntionToGetStream();

foreach (new Tar\StreamReader($stream) as $file) {
    echo "File {$file->getName()} is {$file->getSize()} bytes size.\n";
}

FAQ

Can I use Package for ZIP, RAR, … archives?

No, Package recognize only TAR Archive format, additionaly recognize GZipped or BZipped Archive.

Can I use Package to create/modify Archive?

No, Package provide only read possibility.

Can I search file in Archive?

No, TAR Archive is stream-based format, it does not support search, you must always iterate over whole Archive.

How big file I can proceed?

Here are two scopes of this question: Archive size or Size of files in Archive

• Archive size is teoretically unlimited, beacuse package is using stream very effective.
• Size of files in Archive is teoretically unlimited when use steam-based method to extraxt content (toFile() or toStream()), otherwise is size limited with available memory, because is content filled into variable.
