I am facing a problem here which I could not find a good solution for it. I am developing a mobile web app using php and I need a rule based inference engine (open source) - expert system. The only one I could find was Pyke in Python. So I need to integrate Pykes' source code with my php implementation. My service provider is not allowing any commands such as exec for security reasons. I tried PiP (Python to PHP module) but it has a lot of bugs.
I'm not familiar with Pyke; but when this type of situation arises for me, I usually end up wrapping the Python code with a web-service. I then use PHP to make SOAP or cURL calls to the webservice.

Does anyone know a BPMN 2.0 designer/modeler and process execution engine based on PHP? In the same context, does anyone know an ESB accepting PHP script?
Does anyone know a BPMN 2.0 designer/modeler and process execution
engine based on PHP?
You could use probably almost every PHP framework like symfony to build some ESB functionality into your application but it generaly seems a bit odd to build an ESB in PHP. I don't think PHP is the right technology to that kind of architecture since PHP was developed to be a front end tool. This brings limitation like the lack of non-blocking execution, timeout problems, complicated handling of asynchronus processes.
In the same context, does anyone know an ESB accepting PHP script?
So my recommendation would be:
Check if you really need an ESB *
If you do, choose one among the stable systems, e.g. http://www.jboss.org/jbpm or http://www.mulesoft.org/
Integrate your PHP script as a service using webservices.
* An ESB is not something you can drop in like a jQuery Script so better think twice here.

you could also use a mix of the camunda BPM tools (which all are open source).
The camunda BPM platform with camunda BPM PHP SDK or your own PHP solution via REST API and camunda BPM javascript renderer would provide the process execution and rendering of diagrams for e.g. monitoring purposes.
The camunda BPM modeler (Eclipse Plugin) deals with the modeling/design aspect.
You can find all these tools here
While not a BPMN suite, at least a bit of Workflow is part of ezComponents.
Please be aware, that ezComponents recently failed to get an Apache project after staying some time in incubator...
I have developed a PHP web application, but a client insists on a real Windows application, since he doesn't like running the software inside a browser.
Are there any solutions for this, any compilers to turn a web project into a Windows exe ?
I have looked at Phc-Win , but that seems more suited for small command line utils, not for entire web-applications...
UPDATE:
just found this myself, both look quite promising...

There's no tool for this, short of a simple wrapper app that embeds a browser inside an otherwise normal application window. Your PHP app would have to be completely re-written to include ALL of the overhead code necessary to build a GUI - basically all the 'display' stuff that a browser does automatically, would have to added to your app.

You may look into "HipHop" (made by Facebook): Converts PHP to compileable C++-
There's a tool for this. :-) I never used it but you can try this: Winbinder.
It is simple to compile your PHP source code into an executable. Facebook released a compiler for PHP in early-2010, called HipHop, which aims to create C++. You could then compile this code, for example using gcc, to machine-code.
The more difficult point for a complex Web-App like yours is the user interface. When compiling the way I described above, the application can be run from command line - this might work for simple tasks, but not, if your application returns HTML.
One possibility to solve this problem is PHP-GTK. PHP-GTK is a API for GTK (the graphical user interface used by Linux Ubuntu by default), written in PHP. Using this solution would have to read some documentation about this API, and you would need to rewrite some parts of your program, but it would probably be the most beautiful solution, because it would create a "native" experience.
Another possible solution could involve Adobe AIR, which lets your create programs for the desktop, using HTML, CSS and JavaScript, but I don't know if and how this would work together with your compiled PHP.
Please also note that it isn't absolutely necessary to compile your PHP for it to run on the client's computer; You could also ship the PHP-interperter right with your (uncompiled) PHP-script. Of course, compiling brings benefits, such as faster execution of the program.

I was search for a video platform which I can use as a web-service and install locally on my local server to my PHP website.
I know we can run PHP shell commands but I need to implement a solid system with the Transcoder.
So, it should provide a API using REST or SOAP to convert videos, convert videos in efficient way. Create video thumbnails. If it a ruby or Python then it would be great and should be a free and open source one.
I could see those Software on Github, seems its good but having limitations. https://github.com/streamio/streamio-ffmpeg.
Is this a bad idea to use Perl or Python written application using with PHP? what are the available FOS software
Is this a bad idea to use Perl or Python written application using with PHP?
A bad idea? No. But it can be annoying sometimes.
If you really want to use a web service for this instead of just calling exec/proc_open like the rest of the world, you can go ahead and do that without too much concern.
Another option available to you is Gearman a distributed work queue/RPC service with bindings for many languages, including PHP, Python and Ruby. You can easily write a daemon in Ruby that uses that ffmpeg wrapper, and call methods directly from your PHP code. Thanks to how Gearman works, you can easily scale out the video encoding services by just adding more workers.
You can use FFMPEG binary for conversion/thumb extraction with command line like exec() in PHP
I need to write a small addition to a Python+Django based website, hosted on Google Apps. Trouble is that I don't have any experience with Python.
The addition is pretty straight forward, it requires little database access
So thought of 2 possible solution's:
Quickly dive into Python and get it done with Python.
Run PHP on Quercus and write this particular addition in PHP, then somehow combine it into the website as a dingle PHP page.
Edit: There is another option I thought of:
Writing it in PHP and hosting it on an external server, embedding it in an iframe. The addition I am writing has no need to be SEO friendly, so an iframe will have no negative effect on the website.
What do you suggest?
I am not sure about how you will run php on GAE since it only support Java and Python.
I'd go with solution 1. Python isn't hard to apprehend, you should find ready-to-go code snippets in GAE documentation, and its Datastore doesn't seem too hard to use :D
there's a nice tutorial in GAE documentation: here
Quercus on App Engine runs on the Java runtime, while Python runs on, er, the Python runtime. While you can run one app with multiple runtimes, they have to be different major versions, which means that communication between them will be awkward - you'd have to make URLFetches between them.
I think you'll find it's far simpler to learn enough Python to make the changes. And trust me, you won't regret learning Python. ;)
Google search results suggested that it's possible via PHP/Java Bridge . This bridge requires Java Application Server. My host (bluehost) does not allow to run any Java Application Server. What are the alternatives in this case to make iText work? Switching a host is not viable option for me.
Thanks.
I know this is an old post, but for those still looking for an answer, may I suggest having Java do your work for you as a REST service using Jersey (JAX-RS), then just call the service from PHP. You can put your Java service on a host that does allow Java and you can call that service from PHP using cURL (or even file_get_contents if your host allows it and if you know what you're doing).
Loose coupling over RESTful services is allows you to have your Java service and your PHP app on separate hosts. Don't waste you time with a PHP/Java Bridge. It's perfectly sane to call a RESTful service with a Java back-end from PHP. This way, later if you decide, your would rather re-do the service in C# or something else, at least there will be 0 impact on the PHP app because you used a language neutral RESTful approach.
I have not had any performance issues using this approach myself, YMMV
(It's mostly a matter of design: It's usually better to "bolt" things together then "weld" them together.)
Also, Java with JAX-RS is very very simple (IMHO, but again .. YMMV)
There's always iTextSharp, a C# translation of iText. Will your host let you run C#?
It looks like you can call C# from PHP, as detailed here.
The ITEXT website specifically says JAVA and .NET, Wish they can also build the PHP or PERL version
I have used the Java Itext, Its superb!!
PDFtk is a command line tool installed on many Linux systems. It is a front end to the iText library. It may do what you need. You'd have to shell out to the command line to invoke it from PHP.
