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

说明

public ZipArchive::setPassword ( string $password ) : bool

Sets the password for the active archive.

参数

password: The password to be used for the archive.

返回值

成功时返回 true，或者在失败时返回 false。

注释

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.

ZipArchive::setEncryptionIndex() - Set the encryption method of an entry defined by its index
ZipArchive::setEncryptionName() - Set the encryption method of an entry defined by its name

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';

}



?>

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 .")");

    }

?>
