ZipArchive::setPassword — Set the password for the active archive
$password
)Sets the password for the active archive.
password
The password to be used for the archive.
成功时返回 TRUE
, 或者在失败时返回 FALSE
。
Note:
This function only sets the password to be used to decompress the archive; it does not turn a non-password-protected ZipArchive into a password-protected ZipArchive.

Wouldn't it make sense for this method to be named ZipArchive::usePassword, instead? There seems to be a lot of people thinking that its name, currently (ZipArchive::setPassword), is for applying a password. I think nomenclature should certainly be up for discussion on this method.

As noted earlier the method does not actually set a password. It enters the password to allow decryption of the archive for reading.
It does not:
1) create an encrypted archive
2) allow the addition of encrypted files to the archive
3) read AES256 encryption/compression
4) throw catchable errors use $zip->getStatusString()
Hopefully someone will get around to fixing the doc to reflect all of this.

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 .")");
}
?>

$zip = new ZipArchive();
$code = $zip->open('myzip.zip', ZipArchive::CREATE | ZipArchive::OVERWRITE);
if ($code === true)
echo 'zip opened<br>';
else
echo $code.'<br>';
$zip->addFile('somefile');
$code = $zip->setPassword('secret');
if ($code === true)
echo 'password set<br>';
else
echo $code.'<br>';
$code = $zip->close();
if ($code === true)
echo 'closed<br>';
else
echo $code.'<br>';
echo 'done<br>';
this prints:
zip opened
password set
closed
done
on the filesystem, the myzip.zip is created with somefile inside but the zip file is not password protected.
