PHP 8.1.31 Released!

    ZipArchive::setPassword

    (PHP 5 >= 5.6.0, PHP 7, PHP 8, PECL zip >= 1.12.4)

    ZipArchive::setPassword — Set the password for the active archive

    Description

    public ZipArchive::setPassword(#[\SensitiveParameter] string $password): bool

    Sets the password for the active archive.

    Parameters

    password

    The password to be used for the archive.

    Return Values

    Returns true on success or false on failure.

    Notes

    Note:

    As of PHP 7.2.0 and libzip 1.2.0 the password is used to decompress the archive, and is also the default password for ZipArchive::setEncryptionName() and ZipArchive::setEncryptionIndex(). Formerly, this function only set the password to be used to decompress the archive; it did not turn a non-password-protected ZipArchive into a password-protected ZipArchive.

    It seems that this function supports only decryption of password protected archives (see changelog: http://pecl.php.net/package-changelog.php?package=zip). Creation of password protected archives is not supported (they will be created simply as non-protected archives).

    Example code for extraction of files from password protected ZIP archives:

    <?php
    $zip     = new ZipArchive();
    $zip_status = $zip->open("test.zip");

    if (    $zip_status === true)
    {
    if (    $zip->setPassword("MySecretPassword"))
    {
    if (!    $zip->extractTo(__DIR__))
    echo     "Extraction failed (wrong password?)";
    }

    $zip->close();
    }
    else
    {
    die(    "Failed opening archive: ". @$zip->getStatusString() . " (code: ". $zip_status .")");
    }
    ?>

    To create password protected archive in PHP >= 7.2 use:

    <?php
    $zip    ->setEncryptionName('test.txt', ZipArchive::EM_AES_256, 'test');
    ?>

    Based on example from the documentation:

    <?php

    $zip     = new ZipArchive;
    $res = $zip->open('test.zip', ZipArchive::CREATE);
    if (    $res === TRUE) {
    $zip->addFromString('test.txt', 'file content goes here');
    $zip->setEncryptionName('test.txt', ZipArchive::EM_AES_256, 'passw0rd');
    $zip->close();
    echo     'ok';
    } else {
    echo     'failed';
    }

    ?>
