Are there any PHP functions/libraries that I can use to attach to a running process under the Windows OS ?
I'm playing an abandonware game and I would like to make changes to data in various memory locations whilst the game is running.
The game doesn't use Shared Memory, IPC's. I'm hoping PHP allows me to give the Process ID of the game, and then it can attach using some functions/library that I've not come across.
The GDB debgugger is one potential way forward, but I'd like to do everything in PHP if possible.
Any thoughts or ideas will be appreciated.
With PHP running on Windows you are able to create instances of ActiveX objects. But this will lead you to write an ActiveX class which gets all the information and does all the work. PHP would end for display only purposes and so you could create your html output directly with your ActiveX class / C++ / C# / whatever app.
Summary: For such a task PHP is not the best choice.

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).
I'm just curious about how these websites now a days can create an android apk? i mean what logic is behind it? is it possible that you can compile a code in PHP or is there something else?
e.g. for websites that can generate android apps
http://www.appsgeyser.com/
http://ibuildapp.com/
So just as a student, its killing me to know what they do for it?
Thanks
Nowerdays with the gradle build system that is not too hard. You just need to execute on the commandline gradlew aR and some minutes later you have a brand new apk file.
shell_exec('./gradlew aR');
That should do it's job but keep in mind that this can take some minutes.
A better way would be to queue that job in a database and execute the creation with a cronjob. That would be more secure.
They invoke the Android build tools on automatically generated code to produce the APK.
In fact, they do exactly what you would do to produce an APK, except that some of the code and resources are pre-built (and the same for every application), and whereas you would use Eclipse or Android Studio to compile the code, they are using scripts to so the same thing that the IDE would do.
There exists numerous solutions on generating a thumbnail or an image preview of a webpage. Some of these solutions are webs-based like websnapshots, windows libraries such as PHP's imagegrabscreen (only works on windows), and KDE's wkhtml. Many more do exist.
However, I'm looking for a GUI-less solution. Something I can create an API around and link it to php or python.
I'm comfortable with python, php, C, and shell. This is a personal project, so I'm not interested in commercial applications as I'm aware of their existence.
Any ideas?
You can run a web browser or web control within Xvfb, and use something like import to capture it.
I'll never get back the time I wasted on wkhtml and Xvfb, along with the joy of embedding a monolithic binary from google onto my system. You can save yourself a lot of time and headache by abandoning wkhtml2whatever completely and installing phantom.js. Once I did that, I had five lines of shell code and beautiful images in no time.
I had a single problem - using ww instead of www in a url caused the process to fail without meaningful error messages. Eventually I saw the dns lookup problem, and my faith was restored.
But seriously, every other avenue of thumbnailing seemed to be out of date and/or buggy.
phantom.js = it changed my life.
I've decided to code some applications in PHP that are supposed to run offline in the user's machine. However, I can't seem to find an user-friendly install wizard to create a local server in where the script will run. Any ideas?
PS: Here's an example of what I want: http://www.nolapro.com
You could go to the old school route and try using PHP-GTK.
Text Tutorial here: http://www.kksou.com/php-gtk2/References/Compiling-standalone-PHP-GTK2-applications-on-windows-using-PriadoBlender.php
or you could go the route that I believe has much more promise: Adobe AIR + PHP
It has the added bonus of running on any platform!
Video tutorials here: http://www.vtc.com/products/Adobe-AIR-PHP-Development-Tutorials.htm
There's also a new player in the game, Appcelerator. It lets you write your code in whatever language you want (PHP, Ruby, Python, etc) and compile it for the platform of choice (iPhone, Android, Windows, OSX). Parts of it are still beta, but it looks unbelievably slick & cool, and there are lots of tutorial videos. http://www.appcelerator.com
I hate to advocate this, because it just feels so wrong. You would probably be better off using a language inteded for use for stand-alone applications, if you're going to be doing this often or in a production setting.
With that said, a colleague of mine used to use the Bambalam PHP to EXE Compiler for this. He actually had a profitable product built around it.
Bambalam will generate an EXE that doesn't rely on any external DLLs, based on your PHP code.

If you have a webapp written, you maybe want to deploy on client, a possible way is use wapache, which is a standalone apache bundled with your application, and an integrated (IE) browser control inside.
http://wapache.sourceforge.net/
A new feature of PHP 5.4 & 6 can help you, the builtin web-server.
http://php.net/manual/en/features.commandline.webserver.php
With this feature you can host locally your php app without external webserver, and access on localhost.
If you really talking about a client application you are really wrong to do this.
If you want to wrap a server + browser to deploy your web based application so it runs local you might check out three options:
1) Deploy a simple webkit browser (you can get a QT Webkit Browser in 30 lines of code) and an apache server that is installed somewhere standalone (not via the apache control script as this uses port 80 and i probably conflicts with another installed webserver.
2) Look at the Firefox PRISMA solution. I have read about this only in a news article but it wrapps the firefox around one single start URL. You have to deploy a webserver in the same way as
3) Try to wrap it as a HTA application. Search the corresponding info on MSDN.
I would prefer (1) as you can add special application interacting code as needed.
I've been taken onboard to work on a PHP-based web application. One part of the application generates thumbnail images for MS Office documents on demand, and it uses MS Office + the VeryPDF docprint utility to do this. Because of this one requirement, the system is running on Windows Server 2003 + IIS.
I would prefer to have the system running on a Linux server, rather than MS, as I have far more experience in administering Linux systems than Windows and we have no other in-house technical staff.
Does anyone know a way to handle the document conversion using native Linux software? I would love something PHP native, but am willing to look outside that if necessary.
I have never done anything like this, so I'm just throwing an idea off the top of my head.
Have you thought about utilizing Open Office's capabilities to create thumbnail images? I know OO saves thumbnail images within a created document, so all you need to do is extract the image to display it. (This is demonstrated on the Ubuntu forums.) You could always do something sort of "hackish" where you use run a file through OpenOffice and extract the image to display a small thumbnail.
Again, I have no idea how well this will work, but it may be worth a shot.
To anyone else who comes across this, I have ended up going with the newer version of jodconverter. The sample code includes a basic web page that can be POSTed to using something like Pear's HTTP_Request2. A sample class (by yours truly) which uses this is mentioned in the comments in jodconverter's group on google code.
