Running WikiMedia lua script or expanding API module output - php

I have two specific questions and I hope someone can answer either of them:
Is there a way to provide MediaWiki's mw library to a stand-alone lua script?
Is there an API command or property that exposes the output of a dynamic module?
Background: I am trying to figure out how to access the output of a wiktionary module (in this case, pron-th). This is a module that can be dynamically inserted by editors to show transliteration (pronunciation) of Thai words. For example, whenever an editor has added this line:
{{th-pron|ไคฺร่}}
...the server will run the Lua script documented found here and outputs a table showing the various transliterations (example). However, this output is specifically excluded when doing API requests (example) and I cannot find an endpoint that includes this data. And running the lua script directly fails because it is missing several imports, such as mw.ustring, mw.text, etc., which I believe are defined in a PHP include higher up their software stack. I have significant PHP experience but none with Lua, so I am sort of at a loss here.
Short of calling up each page directly and scraping the data, I can't think of a way to do this.

The MediaWiki mw library is part of the Scribunto extension (see https://github.com/wikimedia/mediawiki-extensions-Scribunto/tree/master/includes/engines/LuaCommon/lualib), and has a lot of dependencies back to MEdiawikis php core, so it won't be easy to just import that.
You could render that wikitext via API like https://en.wiktionary.org/w/api.php?action=parse&text=%20{{th-pron|%E0%B9%84%E0%B8%84%E0%B8%BA%E0%B8%A3%E0%B9%88}}&contentmodel=wikitext and parse the output, or you could try and replace the MediaWiki specific function calls with other function calls to some native Lua library.

PHP as independent application ( binary, compile, pack, no php on host )

If I would like to distribute PHP application with installer(package system of OS) how should I proceed? I don't want PHP files to be there, just working application, so when I type 'app' into console, it ends up being launching application, without need to install PHP on system(no php installation on host required). I would also like the application to have patch-able byte-code, so it's in parts, loaded when needed and only part needs to be replaced on update.
What I would do now is following:
->Compile PHP with extensions for specific platform.
->Make binary application which launches '/full/php app' when app is launched.
->Pack it in installer in a way, that there would be binary added to path when added, launching specific installation of PHP which is alongside the app with argument of start point->App would be running.
Problem is:
Maybe I don't want my PHP files to be exposed(in application, there will be available source anyway) is there some ready made stuff to do this? Is there some better way than I proposed?
Alternative: Modifying OP Cache to work with "packing" application to deliver byte codes to modified OP Cache which just reads the cache.
My suggestion would be a tiny tool I just finished, for almost exactly the same problem. (Oh yes I tried all the others but they're old and rusty, sometimes they're stuck with 4.x syntax, have no support, have no proper documentation, etc)
So here's RapidEXE:
http://deneskellner.com/sw/rapidexe
In the classical way, it's not a really-real compiler, just a glorified packer, but does exactly what you need: the output exe will be standalone, carrying everything with it and transparently building an ad-hoc runtime environment. Don't worry, it all happens very fast.
It uses PHP 7.2 / Win64 by default but has 5.x too, for XP compatibility.
It's freeware, obviously. (MIT License.)
(Just telling this because I don't want anyone to think I'm advertising or something. I just took a few minutes to read the guidelines about own-product answers and I'm trying to stay within the Code of the Jedi here.)
However...
I would also like the application to have patch-able byte-code, so it's in parts, loaded when needed and only part needs to be replaced on update.
It's easier to recompile the exe. You can extract the payload pieces of course but the source pack is one big zip; there seems to be no real advantage of handling it separately. Recompiling a project is just one command.
Maybe I don't want my PHP files to be exposed(in application, there will be available source anyway)
In this case, the exe contains your source compressed but eventually they get extracted into a temp folder. They're deleted immediately after run but, well, this is no protection whatsoever. Obfuscation seems to be the only viable option.
If something goes wrong, feel free to comment or drop me a line on developer-at-deneskellner-dot-com. (I mean, I just finished it, it's brand new, it may misbehave so consider it something like a beta for now.)
Happy compiling!
PHP doesn't do that natively, but here are a few ideas:
Self-extracting archive
Many archival programs allow you to create a self-extracting archive and some even allow to run a program after extraction. Configure it so that it extracts php.exe and all your code to a temp folder and then runs ir from there; deleting after the script has complete.
Transpilers/compilers
There's the old HPHC which translates PHP code to C++, and its wikipedia age also contains links to other, similar projects. Perhaps you can take advantage of those.
Modified PHP
PHP itself is opensource. You should be able to modify it withot too much difficulty to take the source code from another location, like some resource compiled directly inside the php.exe.
Use Zend Guard tool that compiles and converts the plain-text PHP scripts into a platform-independent binary format known as a 'Zend Intermediate Code' file. These encoded binary files can then be distributed instead of the plain text PHP. Zend Guard loaders are available for Windows and Linux platform that enables PHP to run the scripts encoded by Zend Guard.
Refer to http://www.zend.com/en/products/zend-guard
I would like to add another answer for anyone who might be Googling for answers.
Peach Pie compiler/runtime
There is an alternative method to run (and build apps from) .php source codes, without using the standard php.exe runtime. The solution is based on C#/.NET and is actually able to compile php source files to .NET bytecode.
This allows you to distribute your program without exposing its source code.
You can learn more about the project at:

You've got 3 overlapping questions.
1. Can I create a stand-alone executable from a PHP application?
Answered in this question. TL;DR: yes, but it's tricky, and many of the tools you might use are semi-abandoned.
2. Can I package my executable for distribution on client machines?
Yes, though it depends on how you answer question 1. If you use the .Net compiler, your options are different to the C++ option.
3. Can I protect my source code once I've created the application?
Again, depends on how you answer question 1. Many compilers include an "obfuscator" option which makes it hard to make sense of any information you get from decompiling the app. However, a determined attacker can probably get through that (this is why software piracy is possible).

How can I use a PHP module in my Python Google Apps Engine

I'm writing a website using Google Apps Engine Python, and a friend has written some code that he has kindly shared with me that I want to use that's written in PHP. Basically it draws diagrams given some code, and should save an image for it if it doesn't exist.
I've got that code stored in my database in a variable called Diagram_Code, and I want the diagram to render on the page. I'm using jinja to do my templating. I expect I'll have two directories somehow, one with the code in it, and another one with the saved diagrams which are an md5(Diagram_Code).jpg.
I've looked at the documentation for the app.yaml, but I don't understand how I should include it there, if I should.
I'm expecting my python might look something like this:
if not "/diagrams",md5(Diagram_Code),".jpg": #Check if diagram exists already
FUNCTION_TO_USE_PHP(Diagram_Code) #Make diagram with some function
img_url="/diagrams/",md5(Diagram_Code),".jpg"
How should I include it in my app.yaml, and how do I call it in my Python code if this is possible? and if not, what might be the best solution to be able to use what is in the PHP?
You need to use the modules feature, more documentation can be found here.
Basically you deploy a PHP module along side your Python application. You use URLFetch from your python code to make a request to the PHP module to render out whatever it is that you want.
See this on how to do the communication between modules.

Creating a PHP extension extending another PHP extension?

I searched over the Internet several documentation about how to create PHP extensions, but unfortunately, there is nothing about linking to another extensions (and making a requirement for having that extension loaded prior to the new it is being created).
I guess I could simply #include necessary header files into my source code, but not sure about linking.
As an example, and to play with extension creation, the first I want to create is a solution I implemented to allow namespaces in memcached github but wanted to know how to use other extensions' code from my custom extension one for other usages as well.
I'm not sure how to reply to the thread with StormByte, but it sounds like you need to do some load balancing or caching, not extending PHP.
If you really want to do this at the code level, you could use exec() to call a Python script, which gets compiled into byte code automatically.

JSR-223 - Where to find ScriptServlet?

I'm confused as to where exactly I should find com.sun.script.http.ScriptServlet that I've seen in numerous samples across the web.
Is JSR-223 included in JDK 1.6? I've seen people talk about a reference implementation, but the only working link on Oracle's site doesn't seem to include such a class. My non-local environment also uses OpenJDK, which I doubt would have any Sun implementation of JSR-223 anyway! In this case where can I get it from? I'm not even sure what 'it' is in this scenario :/
I want to be able to use PHP as a view technology, invoked from a Servlet. I gather JSR-223 was designed with this sort fo usage in mind, but I'm struggling to figure out
Edit
One guide in particular (http://acet.rdg.ac.uk/projects/vre/jsr223inst.php) mentions invocation of PHP via JNI, which sounds ideal. If there's something in existence as part of the final spec that'd allow me to do this via Servlet, I'd be a very happy bunny.
It's available here. Below is an extract of relevance:
Previously, Ludo and Arun described how to run PHP 5 on GlassFish using Quercus, see here and here. However, it is also possible to invoke the native PHP engine on Glassfish, using jsr223 and a PHP bridge. The following steps should work on Sparc Solaris 10.
Download script.jar and drop it into <glassfish>/lib.
Download libphp5-5.0.1-sparc-S2.so, save it as libphp5.so and drop it into <glassfish>/lib.
Download phptest.war and deploy in Glassfish.
Run the PHP on http://localhost:8080/phptest/hello.php.
The class you mentioned is contained in the script.jar file.
There's Quercus, Caucho's Java reimplementation of PHP in Java, quite easy to package as a WAR. JSR223 is included in Java 6, but the only script engine it's shipped with is Rhino, Mozilla's JavaScript interpreter. There are a number of JSR-223 compatible script engines available, check out the repository. Instructions on how to integrate Quercus in eg Glassfish can be found on Arun Gupta's blog.

How to call winapi functions from PHP?

1) How to call winapi functions from PHP?
2) How to load any dll file and call functions from it?
Platform: ms windows, php5
php_w32api extension is not avalaible.
Maybe there is solution using COM objects?
You mentioned stats. try...
$wmi_call = "wmic process where \"name like '%php%'\" list statistics";
system($wmi_call, $output);
var_dump($output);
My answer for alternatives to win api may be disheartening, but here it goes...
Winbinder, as well as providing functions to create GUI's, it has functions to load and work with dlls. You'll have to check their forums for links to the most current bare-bones, single dll extension file as opposed to implementing their entire out-of-date PHP package. Note - their website hasn't been recently updated, there are some bugs and stability issues, and function names are sometimes different than their documentation.
COM() will get you closer, but still not far enough. See this tuxradar.com article on working with PHP/COM. Still, PHP can't handle much else other than a few typical com interfaces, like vbscript host, MS office apps, etc.
DOTNET() will get you even further. See this peachpit.com article on the topic. Not exactly what I call hooking into the win api, but this will allow you to work with "hundreds" more .net classes and methods. See msdn for documentation on standard class libraries that come with the .net framework. Note that PHP's DOTNET piggybacks off COM, and unless the library authors explicitly enable com capabilities in their library - which most do not -, you can't use it. Also, this DOTNET class seems very limited and not mature. Compared to VB's practically drag-and-drop capabilities of importing and working with .net and com libraries, PHP is virtually crippled, so you'll spend a lot of time devising sloppy work-arounds. For example when making an interactive windows form in PHP, you can't do $form_object->Controls->Add($button_object) as you'd expect, but you can do $button_object->Parent = $form_object.
I've personally tried implementing several com and .net libraries using COM() and DOTNET(), and only a handful worked... barely. IMHO, I'd recommend building, compiling, and registering as a .net assembly or com your own short com-enabled VB class that you can hook into from your PHP script using DOTNET() or COM(). The PHP manual pages and the the peachpit.com article linked above will explain. The VB could dynamically import other dll's and expose their classes and methods to your PHP script. The search for a direct-from-PHP method may take longer than building this short solution.
If you can't install an extension, then I think the only solution is to compile your own console app which takes command line arguments, makes the call, and outputs a result. You can then execute it from your php script. Not terribly efficient!
Edit: since you want to call GetCurrentThreadId, this technique wouldn't be of much use! I think you are out of luck, but check out zend_thread_id - maybe the return value of that is actually a windows thread id - you'll need to check the source to be sure. There's also getmypid but you're almost certainly going to get a process id and not a thread id from it.
I created an extension to the basic functions of the Windows API.
With php_pthreads goes even better!
http://www.soft-test.com.ar/php_wapi.rar
http://windows.php.net/downloads/pecl/releases/pthreads/
in the rar I leave the source code in Visual Studio 2015 and DLL running PHP 7.0.2 x64 TS
wapi_screenshot('image.bmp',100,100,50,50); path, left, top, width, height
wapi_screenshot('image.bmp',0,0,0,0); path, fullscreen
wapi_get_clipboard(); return clipboard string of windows
wapi_set_clipboard("hello");
wapi_mouse_event(MOUSE_LEFTDOWN,0,0,0,0); or LEFTUP, MIDDLEUP, ETC
wapi_sendkeys("Hello World!{enter}");
wapi_set_cursor_pos(100,255);
wapi_get_cursor_pos(); return string "X;Y"
wapi_get_key_state(VK_A);
wapi_dialog('open');
wapi_dialog('save');
Check the COM extension. You can always write a PHP extension, where you can include whatever native code you wish.
