TncWebdav PHP Extension

The TncWebdav extension is a webdav extension for PHP that uses the neon library for webdav operations. It has only been tested with neon version 0.29.6.


This extension was written by Joseph Lambert joseph at The NetCircle. Personal Github page..

This extension initially started out as few bug fixes for webdav-1.2 from pureftpd, but turned into more or less a complete rewrite. Instead of returning a resource and passing the resource to different functions, it is rewritten to use a more OO approach, as well as throwing exceptions in most cases instead of returning only false. It also adds support for PROPFIND and OPTIONS methods, as well as adding a getModTime function to return the last modified time of a file.

However, with all open source software there may be some bugs here and there, so your risk is your own. Also, it is a work in progress.


First, you must install the neon library on the target machine. See the neon website for information on downloading and installing it. After it is installed, follow these steps:

  ./configure --with-tnc_dav
  make test
  sudo make install

If the installed neon libraries cannot be found by shtool, you will need to specify the path to the neon-config binary. An example:

  ./configure --with-tnc_dav --with-neon-config=/usr/local/neon/bin/neon-config

Next, add the extension to your php.ini file:

Note for Windows users

Good luck.

Usage and supported features

The code currently allows the following operations in webdav:

  • GET
  • PUT
  • COPY
  • MOVE

LOCK, UNLOCK and PROPPATCH may be added, but there are no plans for this yet.

Also to be added is handling for HTTPS as well as "other" functions for a more complete implementation.


The following is a usage example:

    $connection = new TncWebdav("http://localhost:8088", "username", "password");

    // Returns true, or throws a TncWebdavException
    // Put a file to the path /my_image.jpg
    $connection->put("/my_image.jpg", file_get_contents("./test_image.jpg"));

    // Get last modified time
    echo $connection->lastModTime('/my_image.jpg'); // Tue Sep  4 14:07:01 2012

    // NOTE: you need the trailing slash (mkcol == mkdir)

    // Move a file from one location to another
    $connection->move("/my_image.jpg", "/testing/test_image2.jpg");

    // Copy from /testing/test_image2.jpg to /test_image3.jpg
    $connection->copy("/testing/test_image2.jpg", "/test_image3.jpg");

    // get file /testing/test_image2.jpg (as a string)
    file_put_contents("./my_new_image.jpg", $connection->get("/testing/test_image2.jpg"));

    // delete file /testing/test_image2.jpg

    // delete file /test_image3.jpg

    // delete directory (must be empty) - REMEMBER THE TRAILING SLAAAASH

    try {
    } catch (TncWebdavException $e) {
      echo $e->getMessage(); // "404 Not Found"
      echo $e->getCode(); // 404

All functions will throw a TncWebdavException if they don't have a 2xx HTTP status code for the operation. The exception message will be the text returned from the DAV server and the error code will be the HTTP status code.


You can test against a Webdav server after running configure by setting two environment variables to set a webdav host and port when you run make test:

  WEBDAVHOST=localhost WEBDAVPORT=8088 make test


The propfind method will return an XML-formatted string of properties for a file. However, it seems the SimpleXML and XMLReader classes in PHP cannot properly parse it. It is formatted according to the WebDAV RFC.


Options will return an array of booleans that correspond to the following class constants:

  • TncWebdav::CAP_DAV_CLASS1 - Class 1 WebDAV (RFC 2518)
  • TncWebdav::CAP_DAV_CLASS2 - Class 2 WebDAV (RFC 2518)
  • TncWebdav::CAP_DAV_CLASS3 - Class 3 WebDAV (RFC 4918)
  • TncWebdav::CAP_MODDAV_EXEC - mod_dav "executable" property
  • TncWebdav::CAP_DAV_ACL - WebDAV ACL (RFC 3744)
  • TncWebdav::CAP_VER_CONTROL - DeltaV version-control
  • TncWebdav::CAP_CO_IN_PLACE - DeltaV checkout-in-place
  • TncWebdav::CAP_VER_HISTORY - DeltaV version-history
  • TncWebdav::CAP_WORKSPACE - DeltaV workspace
  • TncWebdav::CAP_UPDATE - DeltaV update
  • TncWebdav::CAP_LABEL - DeltaV label
  • TncWebdav::CAP_WORK_RESOURCE - DeltaV working-resouce
  • TncWebdav::CAP_MERGE - DeltaV merge
  • TncWebdav::CAP_BASELINE - DeltaV baseline
  • TncWebdav::CAP_ACTIVITY - DeltaV activity
  • TncWebdav::CAP_VC_COLLECTION - DeltaV version-controlled-collection

For example:

  $options = $c->options('/test_image.jpg');

  echo $options[TncWebdav::CAP_DAV_CLASS1]; // bool(true) if it implements RFC 2518

These map to macros in src/ne_basic.h in the neon library. If it returns true, the WebDAV resource has this capability.
