SMB

PHP wrapper for smbclient and libsmbclient-php

• Reuses a single smbclient instance for multiple requests
• Doesn't leak the password to the process list
• Simple 1-on-1 mapping of SMB commands
• A stream-based api to remove the need for temporary files
• Support for using libsmbclient directly trough libsmbclient-php

Examples

Connect to a share

<?php
use Icewind\SMB\ServerFactory;
use Icewind\SMB\BasicAuth;

require('vendor/autoload.php');

$serverFactory = new ServerFactory();
$auth = new BasicAuth('user', 'workgroup', 'password');
$server = $serverFactory->createServer('localhost', $auth);

$share = $server->getShare('test');

The server factory will automatically pick between the smbclient and libsmbclient-php based backend depending on what is available.

Using anonymous authentication

$serverFactory = new ServerFactory();
$auth = new AnonymousAuth();
$server = $serverFactory->createServer('localhost', $auth);

Using kerberos authentication

$serverFactory = new ServerFactory();
$auth = new KerberosAuth();
$server = $serverFactory->createServer('localhost', $auth);

Note that this requires a valid kerberos ticket to already be available for php

Upload a file

$share->put($fileToUpload, 'example.txt');

Download a file

$share->get('example.txt', $target);

List shares on the remote server

$shares = $server->listShares();

foreach ($shares as $share) {
	echo $share->getName() . "\n";
}

List the content of a folder

$content = $share->dir('test');

foreach ($content as $info) {
	echo $info->getName() . "\n";
	echo "\tsize :" . $info->getSize() . "\n";
}

Using read streams

$fh = $share->read('test.txt');
echo fread($fh, 4086);
fclose($fh);

Using write streams

$fh = $share->write('test.txt');
fwrite($fh, 'bar');
fclose($fh);

Note: write() will truncate your file to 0bytes. You may open a writeable stream with append() which will point the cursor to the end of the file or create it if it does not exist yet. (append() is only compatible with libsmbclient-php)

$fh = $share->append('test.txt');
fwrite($fh, 'bar');
fclose($fh);

Using notify

$share->notify('')->listen(function (\Icewind\SMB\Change $change) {
	echo $change->getCode() . ': ' . $change->getPath() . "\n";
});

Changing network timeouts

$options = new Options();
$options->setTimeout(5);
$serverFactory = new ServerFactory($options);

Setting protocol version

$options = new Options();
$options->setMinProtocol(IOptions::PROTOCOL_SMB2);
$options->setMaxProtocol(IOptions::PROTOCOL_SMB3);
$serverFactory = new ServerFactory($options);

Note, setting the protocol version is not supported with php-smbclient version 1.0.1 or lower.

Customizing system integration

The smbclient backend needs to get various information about the system it's running on to function such as the paths of various binaries or the system timezone. While the default logic for getting this information should work on most systems, it is possible to customize this behaviour.

In order to customize the integration you provide a custom implementation of ITimezoneProvider and/or ISystem and pass them as arguments to the ServerFactory.

Testing SMB

Use the following steps to check if the library can connect to your SMB share.

1. Clone this repository or download the source as zip
2. Make sure composer is installed
3. Run composer install in the root of the repository
4. Edit example.php with the relevant settings for your share.
5. Run php example.php

If everything works correctly then the contents of the share should be outputted.
