Developing a PHP/mySQL app on IIs - php

I am strictly a LAMP dev but an ad agency I work with is courting a government agency whose RFP requires that their site be delivered via a Windows server.
What advice do folks have on this? Are there specific pitfalls? It seems like I have heard that file uploads and folder permissions are very different on Windows servers.
Any advice would be greatly appreciated.

IME, IIS can behave very oddly at times.
The permissions model is primarily ACL based - so its certainly possible to design a system which mimics the way Unix works - but (just as with Unix) get the permissions model right - and don't tinker with permissions / ownership in your code.
And of course you'll get yourself tied in knots if you try to move up directory hierarchies and cross over 'drives'.
Add to that a complete absence of the services you might invoke via popen(), and the POSIX tools.
Yes, people keep telling me its a nice place to visit but I wouldn't want to live there.
OTOH, a self-contained set of PHP files will run quite happily there.

PHP on a windows server is definitely trying on your patience. Problems that I've run into are making sure that IIS is configured to use the correct php.ini file, and as you said, writing to files on the server as well as folder permissions.
That being said, if you can get it working correctly, it's not a bad production environment.
I would suggest getting your dev environment as similar as possible to what production will look like. That way you run into as few problems as possible when you deploy.

I can see some pitfalls for using PHP on IIS
Since IIS is multithreaded unlike
linux which is multiprocess. Some
PHP scripts might be unsafe.
Because of this PHP should be installed and
run as a CGI extension. CGI is
slower than IIS's ISAPI and worse
when compared to Apache's mod_php.
Another pitfall I can think of is URL rewriting. IIS, versions below
v7 do not support url rewriting.
Configuration of PHP with IIS is really a pain. But when you do configure it, make sure you use the same configuration, exact mirror images everywhere you are developing because a lot can go wrong with just one glitch.

Debian 8 multiple PHP are these safe methods?

At work i want to upgrade our system to PHP7. It is currently at PHP5.6.
We have a different folder structure, as we have all our code in the /home/user directory.
I am not a server guy, i only code. But i know some linux basics.
I came across phpbrew. Is it safe for me to use? as we have a different folder structure then most have.
I dont want to mess up my development server, so it is important for me that i can switch back to 5.6. The server is running debian 8 and we use apache2.
I also came across this article:
https://lornajane.net/posts/2016/php-7-0-and-5-6-on-ubuntu
Is this a safe way to do what i want?
Any other suggestions are also welcome!
Thanks in advance!
The process described in that link looks plausible. Possibly other online resources might confirm it. Why not make a quick VM and try it out?
Is your current dev server a VM? You could clone it, then make the changes and run both in parallel. If not, you could shut it down briefly, image it, and then use the image to build a VM or another physical box.
That way you've got any custom server setup copied across reliably with minimal effort, and you can test PHP7 along with that stuff, with no risk to the current environment. That would be my advice.

Debugging php applications on folders different than 'xampp/htpdocs' with PhpStorm

I know this may be a long and general question but I am struggling with it for the past two days and have achieved nothing.
I am a C# .net developer and I use Visual Studio IDE for my development which does all the back-end work for me when creating projects, setting virtual hosts, publishing the project and etc.
Now for some reasons I have to do a project in PHP and I chose PhpStorm as my IDE. I installed XAMPP and the Apache server is working ok, and I set its' php executable as an php interpreter in PhpStorm.
I don't want all my projects to be in xampp/htpdocs so I choose another location (d:\projects\phpStorm\<name of the project>) as my working space when I first created a project.
I installed xdebug using the tutorial it gave me:
Download php_xdebug-2.4.0rc4-5.6-vc11.dll
Move the downloaded file to C:\xampp\php\ext
Edit C:\xampp\php\php.ini and add the line
zend_extension = C:\xampp\php\ext\php_xdebug-2.4.0rc4-5.6-vc11.dll
Restart the webserver
And I can confirm that it is installed using phpinfo() in a php file located in xampp/htpdocs.
My problem is with the debugging. When I click Run->Run in an opened php file in PhpStorm, it uses a free port and opens the php file with a url like this: localhost:port_number/<name of the project> and everything is ok.
Now I followed this tutorial to configure the xdebug. In step two, when I go to Run->Web Server debug validation, fill the Path to create validation script with d:\projects\phpStorm\<name of the project> and Url to validation script with localhost:port_number/<name of the project> (as mentioned above) and click validate I get this information (and an error in the last line):
Server Name: PhpStorm 10.0.3
Loaded php.ini: C:\xampp\php\php.ini
No debug extension is loaded
Follow this links to configure Xdebug or Zend Debugger. If you have
already configured debug extension in php.ini file check possible
reasons why it was not loaded:
You forgot to reload web server after changes in php.ini file.
You are configuring debug extension in the wrong php.ini (see the
loaded php.ini files below).
There are errors on attempt to load debug extension, e.g. version
incompatibility.
I want to know what should I do?
I really really want to set my projects in another location other than xampp/htpdocs to organize them properly, just like I do it in Visual Studio. So please don't suggest solutions involving me changing my working directory.
Thanks in advance.
P.S.: In JetBrain's tutorial, I see that the xdebug's IDKEY is PHPSTORM whereas mine is my pc's username, it it ok?

Well you're really going to hate this then, but unfortunately Apache (which is what php runs on) only recognizes htdocs (or public_html, or www, depending on what specific server you are running, but anyhow in your case only htdocs) as a valid directory for php execution. Sooooo...
That doesn't really mean this is hopeless, but you might have to jump through some silly hoops to get it to work this way.
Option 1
You may have some luck creating a symbolic link from .htdocs to your projects folder from the command line:
ln -s C:xampp/htpdocs d:/projects/phpStorm
If you're on windows, this probably won't work. It also likely won't work between drives. It also may not work depending on your Apache configuration in XAAMP.
PROS: If it works, will do exactly what you want.
CONS: Probably won't work, if it does, will require nightmarish levels of config fiddling
Option 2
Use a remote development server, and sync over FTP with your IDE. I'm not super familiar with PhpStorm, but I can pretty easily do this in Netbeans or Eclipse. This is a good option when you need a local archive of a project retained. You might be able to set up an FTP server on your machine and accomplish this, however you are going to wind up with two copies of your project; one in your projects folder and the other in htdocs.
PROS: Your projects stay organized where you want them without much issue.
CONS: File duplication, they will have to be in htdocs anyhow for Apache to run php
Option 3
Accept that the technology is not designed to work this way and just put everything in htdocs where it belongs. Resisting the way technology works because you are used to a different workflow is how design flaws and really bad bugs happen. Use it the way it was meant to work and don't be scared of learning new things.
PROS: No conflicts with the XAAMP stack whatsoever
CONS: You specifically stated you don't want to do it this way, but this is really the best way
Option 4 (Don't do this)
Install PHP as a globally accessible command line utility across your entire system, and consequently get all kinds of crazy viruses and errors that you may not be able to fix ever.
PROS: Minor alleviation of aggravation with foreign workflows
CONS: All of the things. The worst things.
Option 5 (probably not going to work)
Try using VirtualHosts. There's a bunch of caveats with this though. First, doing this between different drives is nearly impossible to configure correctly due to security policies in your operating system that are difficult to overrule. Second, if you're on Windows (I assume you are if you are using XAAMP), you need to do all of the following:
-In apache.conf, you need to enable your hosts file.
-In the vhosts file, you need to create a new vhost.
-In the windows hosts file, you also need to create a host, because for whatever reason windows likes to arbitrarily add redundant steps. On every other OS, this step is not neccessary. Also, you need to run your text editor as administrator to even do this at all.
-Restart apache when it's all set up
-Pray your machine will let you do this between drives (C: -> D:), or not take a million years to enable.

What is needed for a user to download and run a PHP application?

I'd like to develop a PHP application that users would download and then could run. The application will have a web service.
I assume they will need Apache, but my main question is what is needed for PHP to run on their machine? Is there something needed like the JVM in Java or the .Net framework in .Net? What is it called and how difficult is it for them to download (size, etc.).
Is anything else required that I did not mention?
Thank you,
They will need a web server with a compatible version of php. That's it.
Are you asking what is required to run a .php file on a windows machine? Do you mean like an executable or a web server script?
If like an executable need the php files:
Download the php installer from http://windows.php.net/download/, and then you can run php.exe script.php
If like a web site:
You need a webserver (like apache) and the php.exe files. I would suggest if testing to download a prebuilt webserver like XAMPP (download from http://www.apachefriends.org/en/xampp-windows.html)
It depends on the application. At a minimum it will need PHP.
Is there something needed like the JVM in Java or the .Net framework in .Net? What is it called and how difficult is it for them to download (size, etc.).
PHP. Presumably as difficult as it is for you, but it depends on the platform. OS X comes with it. Most Linux variants either come with it, or allow it to be installed with one command to the package manager. Windows users will have to download it seperately.
As for other things that might be needed…
If it has a GUI, it might need PHP-GTK.
If it expects to be accessed via HTTP then they will need a webserver which supports PHP. This could be Apache, IIS, or one of numerous other servers.
(It isn't clear if, when you say "The application will have a web service.", you mean "The application will access a web service" or "The application will provide a web service". If the latter, then a web server will be needed).
If you use any non-core modules, then they will be needed as well.
You need to describe your proposed application a bit better. Is there a reason the application must be in PHP? It may be possible, but it's certainly not common to code and distribute a desktop application written in PHP.
There are a few options.
If you are just writing a script (command line, etc) you don't need a webserver. You just need PHP installed to run it (there are even downloadable installers for it).
If you are writing a web-based tool, then you will need your users to have a webserver if they are meant to run it on their physical machines. And you don't need a framework...
just think of it as a Webserver + PHP as a plugin. Some webserver options: Apache, nginx, lighttpd
Try having users install WAMP, MAMP, or Zend Server CE all of which are free and come with both a webserver and PHP.
If you really want a deployable PHP script/tool, maybe look into something like PHPDock, which gives your users a single installable app (embedded server, php). NuSphere PHPDock
Honestly, it's not the greatest language to use for this type of deployment, but it's certainly fun to try to figure out! Sorry for not linking out also, don't have enough rep points for all of the links I had intended to supply.
Actually you can run php script without the need to have a webserver installed.
Just install php and then from command line:
$ php myscript.php
If you really want you can even build GUI application with php even though I would not suggest it.
Cheers Andrea
you could also try to use quercus.
Quercus is Caucho Technology's fast,
open-source, 100% Java implementation
of the PHP language (requires JDK
1.5).
This way you only will need a jvm+quercus. It also is platform independent this way because it runs in the JVM.

Building a CMS in PHP: Development tools

I'm planning to build a CMS in PHP and MySQL, mainly for my own amusement and education. (Though who knows, I may come up with something useful and cool. Anything's possible.) I'll be asking questions about code architecture etc. later. For now, I'm more interested in development tools.
So far, all my playing with code has been done on a web server, and I've edited over FTP. I was thinking it might be quicker to use a localhost. Also, that way, I could use version control (which I've never done before).
So,
A. How do I set up a localhost server with many subdomains on an Ubuntu 9.10 computer. Is XAMPP for Linux the way to go, or should I use a standard Apache distro? (Or another webserver altogether?) For that matter, is it possible to set up more than one webserver on the same computer, and to use them for different localhost subdomains?
B. How do I set up a version control thingy covering all the code (which will be on several subdomains of localhost, and in a few shared folders)? I've read Joel Spolsky's HgInt tutorial, and it makes Mercurial look good. And simple, especially if you're working on your own.
C. Should I continue to use gEdit to write HTML/CSS/JS/PHP, or is there a better free editor out there for these languages?
A. Why would you use XAMPP when installing a LAMP stack is as easy as sudo tasksel install lamp-server? You can add as many domains to the configuration as you want using VirtualHosts for example (well theoretically anyway, in practice the amount will be limited by the available resources), you don't need multiple servers for that.
B. sudo apt-get install mercurial maybe? Of course, how to create a repository and add your projects is up to you - you should read the documentation of Mercurial.
C. Use Eclipse or NetBeans if you're planning to do any serious development work.
I'd recommend against using XAMPP, particularly if you're inexperienced as this would bypass all the package management functionality integrated in Ubuntu (so you need to manually track and apply security changes, if you need extensions not in the XAMPP distro you'll need to compile from scratch, similar for most of the external admin tools which might interact with the Apache install).
Yes - you can have lots of virtual hosts on the same webserver (rcently worked somewhere with 1200 named virtual hosts on each Apache webserver - start up took about 2 seconds rather than 0.5 - but after that you'd never have known the config files were HUGE).
If you're working on your own, then this is about the only scenario where using a distributed version control system offers no benefits over concurrent version control system, and a concurrent version control system offers no benefit over a conventional version control system. But even though it offers no advantage in the technology, it may be of benefit to you to acquire specific product skills.
What editor you use is matter of personal choice. Though personally I would list gEdit in my recommendations (I'd suggest NetBeans or Zend Studio for people who like standalone IDEs, otherwise vim, Eclipse, emacs).
A php documentor is (IMHO) a must (I like phpxref) along with some sort of testing toolkit.
HTH
C.
A: I've used Xampp for Linux successfully on Ubuntu. It's not hard to setup a normal apache installation, but I like the advantage of having a "temporary" web server where the changes are easy to reverse without affecting my normal installation.
If you want subdomains, configure apache to use virtualhosts.
B: I suggest subversion, but VCS is something of a religious issue. It doesn't matter what you use particularly. Once you've made a choice, then research the usage of a VCS.
C: Netbeans is much better than gEdit. That or Eclipse would be my preference. I use Netbeans under Ubuntu myself. A full IDE though will make development much easier than a text editor. Mostly because of code completion/integrated debugger.
I think stackoverflow.com is for programming questions. You'd want to ask those server questions on serverfault.com. Then again, they'd probably ask you to google it. Give it a try.
The editor question is cool. I use Kate, just because it comes with KDE and has syntax coloring.

PHP Deployment to windows/unix servers

We have various php projects developed on windows (xampp) that need to be deployed to a mix of linux/windows servers.
We've used capistrano in the past to deploy from windows to the linux servers, but recent changes in architecture and windows servers left the old config not working. The recipe works fine for the linux deployment, but setting up the windows servers has required more time than we have right now. Ideas for the Capistrano recipe are valid answers. obviously the windows/linux servers don't share users, so this complicates it a tad (for the capistrano assumption of same username/password everywhere).
Currently we're using svn-update for the windows servers, which i dislike, since it leaves all the svn files hanging on the production servers. (and we still have to manually svn-update them on windows) And manual updating of files using winscp and syncing the directories with their linux counterparts.
My question is, what tools/setup do you suggest to automatize this deployment scenario:
"Various php windows/linux developers deploying to 2+ mixed windows/linux machines"
(ps: we have no problems using linux tools or anything working through cygwin, we simply need to make deployment a simple one-step operation)
edit: Currently we can't work on a all-linux enviroment, we have to deploy to both linux and windows server. We can start the deploy from anywhere, but we'd prefer to be able to do it from either enviroment.
I use 4 different approaches depending on the client environment:
Capistrano and similar tools (effective, but complex)
rsync from + to Windows, Linux, Mac (simple, doesn't enforce discipline)
svn from + to Windows, Linux, Mac (simple, doesn't enforce discipline)
On-server scripts (run through the browser, complex)
There are some requirements that drive what you need:
How much discipline you want to enforce
If you need database (or configuration) migrations (up and/or down)
If you want a static "we're down" page
Who can do the update
Configuration differences between servers
I strongly suggest enforcing enough discipline to save you from yourself: deploy to a development server, allow for upward migrations and simple database restore, and limit who can update the live server to a small number of responsible admins (where the dev server is open to more developers). Also consider pushing via a cron job (to the development server), so there's a daily snapshot of your incremental changes.
Most of the time, I find that either svn or rsync setups are enough, with a few server-side scripts, especially when the admin set is limited to a few developers.
This will probably sound silly but... I used to have this kind of problem all the time until I decided in the end that if I'm always deploying on Linux, I ought really to at least try developing on Linux also. I did. It was pain free. I never went back.
Now. I am not suggesting this is for everyone. But, if you install VirtualBox you could run a Linux install as a local server on your windows box. Share a folder in the virtual machine and you can use all your known and trusted Windows software and techniques and have the piece of mind of knowing that everything is working well on its target platform.
Plus you'll be able to go back to Capistrano (a fine choice) for deployment.
Best of all, if you thought you knew Linux / Unix wait until you use it everyday on your desktop! Who knows you may even like it :)
Capistrano is the nicest deployment tool I've seen. Do the architecture changes make it impossible to fix the configs so it works again?
Why you can't use capistrano anymore?
Why you dislike svn-update?
What things in your app requires an special deployment ?
You can setup svn:ignore property on configuration files, so that svn update doesn't erase them, and then use svn export /target/path/ to get rid of .svn files in your Subversion repository.
