• Support zip password for PHP 5.5, include update and remove password.
• Support encryption method Traditional PKWARE Encryption (ZipCrypto) and WinZIP AES Encryption.

• Support archive alignment functional zipalign.

Requirements

• PHP >= 5.5 (64 bit)

Installation

composer require nelexa/zip:^3.0

Examples

// create new archive
$zipFile = new \PhpZip\ZipFile();
$zipFile
    ->addFromString("zip/entry/filename", "Is file content")
    ->addFile("/path/to/file", "data/tofile")
    ->addDir(__DIR__, "to/path/")
    ->saveAsFile($outputFilename)
    ->close();
        
// open archive, extract, add files, set password and output to browser.
$zipFile
    ->openFile($outputFilename)
    ->extractTo($outputDirExtract)
    ->deleteFromRegex('~^\.~') // delete all hidden (Unix) files

Open Zip Archive

Open zip archive from file.

$zipFile->openFile($filename);

Open zip archive from data string.

$zipFile = new \PhpZip\ZipFile();
$zipFile->openFromString($stringContents);

Open zip archive from stream resource.

$stream = fopen($filename, 'rb');

$zipFile = new \PhpZip\ZipFile();

Get Zip Entries

Get num entries.

$count = count($zipFile);
// or

• Rename methods:
  • addFromFile to addFile
  • setLevel to setCompressionLevel
  • ZipFile::setPassword to ZipFile::withReadPassword
  • ZipOutputFile::setPassword to ZipFile::withNewPassword
