How to Install a WebDAV Server in PHP

How to install a webdav server in PHP

It's very simple.

• Download this package, and decompress it.
• The inc folder contains PEAR and the HTTP_WebDAV_Server class.
• Copy the inc folder and authenticate.php file in the include_path (see php.ini)
• Copy webdav.php file in the root of your site.

The authenticate.php file contains a digest authentification.

The webdav.php file create a webdav server

include_once("authenticate.php");

ini_set("error_reporting", "");

# Name of your restricted area
$realm = 'Restricted area Keyphrene';
$DBUSER = "your login";
$DBPWD = "your password";
$users = array($DBUSER => $DBPWD);
# With this authentication method, 
# your password is not readable when you use this service
AuthenticationDigestHTTP($realm, $users);
# AuthenticationBasicHTTP($realm, $users);

require_once "HTTP/WebDAV/Server/Filesystem.php";
$server = new HTTP_WebDAV_Server_Filesystem();
# Database configuration for the lock method
$server->db_host = $DBHOST;
$server->db_name = $DB_WEBDAV;
$server->db_user = $DBUSER;
$server->db_passwd = $DBPWD;
# Real path of your site
$server->ServeRequest($DOCUMENT_ROOT."/www/");

?>

To use this service, you must connect you at this adress http://mysite.org/webdav.php. You can configure a lot of access on your site. Becareful, if you must copy files on your server, you must use the good permissions with the FTP client.

LIBNAME Statement Support for WebDAV Servers

   LIBNAME statement support for WebDAV servers will be available for use
  in SAS® 9.1.3 (9.1 TS1M3) with hot fix D9BA08, which is currently
  under production.

  The LIBNAME statement is being extended to allow access to content
  stored in a Web Distributed Authoring and Versioning (WebDAV) server.

  Syntax

  LIBNAME libref  'SAS-library'  WEBDAV USER="user-ID"
           PASSWORD="user-password";

  Where 'SAS-library' specifies the URL location (path) on a WebDAV
  server. The URL specifies either HTTP or HTTPS communication protocols.

  Only one data library is supported when using the WebDAV extension to
  libnames. REMOTE engines are not supported with the WebDAV options.


  WebDAV Specific Options

  WEBDAV
  specifies that the libref accesses a WebDAV server.

  USER="user-ID"
  specifies the user name for access to the WebDAV server. The user-ID is
  case-sensitive, so it must be in single or double quotes.
  Alias:       UID

  PASSWORD="user-password"
  specifies a password for the user to access the WebDAV server. The
  user-password is case-sensitive, so it must be in single or double
  quotes.
  Alias:       PWD=, PW=, PASS=


  Data Set Options

  The following table lists the data set options that have different
  functionality when using a WebDAV server. All other data set options
  will function as described in the SAS Language: Reference.

  Data Set Option Functionality with WebDAV

  Data Set Option  WebDAV Storage Functionality

  CNTLLEV=         LIB locks all data sets in the library prior to writing
                   the data into the local cache. All members are unlocked
                   once the data step has completed and the data set has
                   been written back to the WebDAV server.

                   MEM locks the member prior to writing the data into the
                   local cache. Member is unlocked once the data step has
                   completed and the data has been written back to the
                   WebDAV server.

                   REC is not supported. WebDAV will only allow updates to
                   the entire data set.

  FILECLOSE        VxTAPE engine is not supported, therefore this option
                   is ignored.

  GENMAX=          This functionality is not supported because the maximum
                   number of revisions to keep cannot be specified in
                   WebDAV.

  GENNUM=          If present, the specific version specified isnot
                   retrieved from the WebDAV server for read-only access.

  IDXNAME=         Users can specify an index to use if one exists.
                   However, to use this option, you need to
                   have accessed the data set (to get it locally) then
                   created an index so that it would be available.

  INDEX=           Indexes may be created in the local cache and used in
                   subsequent DATA steps.

  TOBSNO=          Remote engines are not supported, so this option
                   is not needed.


  Details

  When accessing a WebDAV server, the file is pulled from the WebDAV
  server to your local disk storage for processing. When you complete the
  updating, the file is pushed back to the WebDAV server for storage. The
  file is removed from the local disk storage when it is pushed back.

  Example

  The following example associates the libref davdata with the WebDAV
  directory /users/mydir/datadir on the WebDAV server www.webserver.com:

  libname davdata v9 "https://www.webserver.com/users/mydir/datadir"
          webdav user="mydir" pw="12345";
