[gdal-dev] New PHP bindings - php5-gdal
Hi, I am writing a PHP 5 module providing bindings for GDAL and OGR. It is GPL3-licensed and available here: http://projects.geonef.fr/projects/php5-gdal/wiki It is far from complete, bindings are available for about a third of the C++ interfaces. I have been working on/with it for 8 months yet, and recently using it on a production website as well. I actually wrote the bindings I needed so far, the rest will follow little by little, and any contribution is welcome. php5-gdal provides PHP classes for the equivalent C++ class, same for the methods. The C macro constants of GDAL/OGR are brought to PHP as global constants. I decided to write this library when I got limited at using OGR/PHP (segfault crash) and noticed the latter has not been maintained for years. After trying to compile the SWIG bindings with no success, I thought a good robust C++ code would be the best deal for providing OOP interfaces to PHP. As the GPL summary says, I hope that this library will be useful! There is a dedicated ML, info on http://ml.geonef.fr/mailman/listinfo/php5-gdal-dev Best regards, Jean-François Gigand - Geonef Paris, France - http://geonef.fr/ ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev

With a notice that these bindings are yet incomplete. I will soon update the wiki to list all available classes, methods, functions and constants. Would be good to have an API doc in php.net-style, if that's easy to do. I have a few questions about prototype guidelines and how the php5-gdal API should conform to. Closer to the GDAL/OGR C++ API or closer to PHP's best practices? For example, should the constants be kept in the global space, or should they move to class constants? I also have questions about error management (use exceptions?) and whether values returned through reference args should be returned instead (such as arrays). So far, I have stayed as close as possible to the GDAL/OGR API. Is there anyone experienced with this type of issues, a foot in PHP and another in C++ or GDAL, that I could discuss with? > >>> It is GPL3-licensed and available here: >>> http://projects.geonef.fr/projects/php5-gdal/wiki >>> >> I'm wondering if it would'nt be more apprioprato to use the same license >> as GDAL itself, see http://www.gdal.org. >> > > Ideally BSD (in my mind), or at the minimum LGPL to make it clear that PHP > code using it will not be bound by the GPL. > > (It is not clear to me whether scripting function calls to a CPL module > makes the calling code bound to GPL as well. BSD or LGPL would avoid the > question.) I should have asked prior advise about what license suits best. I'm not a specialist, but I agree that GPL is too restrictive for such a library. Since this work is nothing compared to the (amazing) set a features provided by GDAL, it would be coherent that it inherit from the same license. Moreover, PHP frameworks like Zend's or Symfony have a BSD-style license. I checked the PECL repository and most packages appear to be released under the PHP license (http://www.php.net/license/3_01.txt), which seems to suits PHP itself better than third-party extension modules. So, I'm ok with choosing X11/MIT, unless any other strong advise is expressed. > >> BTW: I'm not able to access to the above mentioned address. > > There seems to be a password protection. > So sorry, there were per-IP rules that mislead my verification.

Re: [gdal-dev] New PHP bindings - php5-gdal
Hi Thomas, I actually noticed that initiative 2 days ago by searching the ML, posts dated from around March. If I had seen them on that time, I would have shared my code earlier. I never used SWIG. When I wondered in last December if I should leverage SWIG or write a C++ PHP extension, I chose the latter when I noticed that the PHP SWIG bindings in GDAL were very old. I was also encouraged when I noticed that for MapServer, the PHP MapScript extension is written in core C, although they use SWIG for some other languages like Python. Mike Leahy, have you got anything working with the SWIG bindings? Since you know SWIG, what do you think about this choice?

Re: [gdal-dev] tiled vector rendering
Hi Rashad, There is MapServer, http://mapserver.org/ It supports GDAL and OGR sources as input. It's not the only one but one of the most famous.

Re: [gdal-dev] tiled vector rendering
There is QuantumGIS : http://www.qgis.org/ Again, not the only one. GRASS can also read GDAL/OGR datasources. Not sure if gvSIG uses the GDAL library, but it supports many formats.

Re: [gdal-dev] tiled vector rendering
I don't know OSSIM, and I don't understand what you really need to do. You should understand the concepts first, then express what component you need, for given inputs and outputs. "tiled vector rendering engine": does that mean rendering vectors to an image given style rules, or split large vectors into geographical square tiles of vectors ?

Re: [gdal-dev] New PHP bindings - php5-gdal
Hi, I have update the license of php5-gdal to the same as GDAL (I copied the license block). The project website is: http://projects.geonef.fr/projects/php5-gdal/wiki If you want to add a link to http://trac.osgeo.org/gdal/#GDALOGRInOtherLanguages, the project is ready for it.
