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 .")");
}
?>
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
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
注意:
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';
}
?>
