I have a Windows Azure subscription.
My requirement is to run a PHP script on my server. This PHP script will create a JSON file.
This JSON file will be downloaded by my iOS app. (Some kind of authentication is an added bonus)
How would I go about doing this? Should I create a "Mobile Service" or should I create a "Website" or something else like "Cloud Services"?
As far as I have researched, I think the only way to do this would be the old school website way. Any input on this will be really helpful. Thanks.
Mobile services are great if you want to create a quick CRUD layer for an app with a backend cloud storage such as Azure SQL DB. It also provides support for scheduled tasks and push notification. But for what you're after (producing a JSON file), you may find it easier to go with Azure Web Sites or Azure Cloud Services (PaaS). Azure Web Sites has a model that you'll likely find easier and with the free/shared tiers, provides a lower cost point for many models. If you want something that gives you a bit more control, then Cloud Services might be a good alternative as well. But given the simple example you've provided, you should be able to accomplish this fairly quickly using Web Sites.

I'm building a mobile project that needs to be in constant communication with a server and i need some information . I know how to build local apps but this is the first time that i'm building an app that requires external call to a server / authentication service .
I'm asking for guidance how to proceed and which services/servers to use.
What type of server/database do i need ?
I'm guessing i will be requiring an API service but no idea how to choose/make one.
I want to use azure services/database but i also don't want to be dependent on it. I want to have my own url that i send request to and interact with a server/db that i can later move to another host fairly easily.
I develop websites mostly and i'm familiar with php/laravel + Mysql but i think in this case it will be overkill to create a laravel app simply for the server backend .
The app will be mobile only so i don't expect to have a webpage for it . simply an external server/database where the data will be saved.
First i need an authentication service - where each user will register on the phone which will then be saved in my external server/database . Then when they need to login - they will input the login details on the phone , which will query the esternal server/database and if validated - get their details from the server.
First, you need to decide which kind of server communication you'll need. it's in real time and constant? then you'll need a websocket. It's in bursts when you need to send or get data? then you'll need some kind of webservice (REST, RPC, SOAP). Then you have to evaluate the user load you'll have. And finally, the human resources you'll have.
Based on your question, I think a REST webservice will be more than enough. You may:
-Create a REST service for every group of related resources. Example: the /user URL should handle the signup, login, logout and user update operations.
-Create a method for each one of those operations and handle them. Then, call the method from the REST service class.
-Depending on the amount of users and the technology you're using, create a server to handle the requests, or upload your REST project to a server (tomcat, for example).
-Create an app and consume the REST services from there.
There are tons of tech you can choose for these things. PHP allows creating REST services, I think. Java is a very good choice too, since you can use the same code in both server and android apps. Node.Js is pretty popular, too, since you don't need servers and uses NIO (althought java can do both things using jetty and also has multithreading); golang and scala both have superb performance (golang is a lot more easier to learn, though, and it has no need to use external webservers).
Hope this helps.
For mobile applications the best will be REST (representational state transfer),becouse is lightweight and flex to use in other technology. I had project which include REST and mobile app and web app and it working very well.
In this scenario, we usually will build a REST API service for client end. As you are familiar with Laravel, you can refer to http://www.programmableweb.com/news/how-to-build-restful-apis-using-php-and-laravel/how-to/2014/08/13#apiu for how to build a REST API service with Laravel. Also you can leverage other light 3rd part PHP frameworks to build REST API service.
You can create and develop the application on local and then deploy to Azure Web Apps. Please refer to https://azure.microsoft.com/en-us/documentation/articles/app-service-web-php-get-started/ for more info.
And there several vendors provide MySQL services on Azure. ClearDB is a BaaS on Azure for MySQL. You also can use the VM to host your MySQL Service. E.G. MySQL by Bitnami and MySQL by Docker.
I'm currently developing an iOS app and have reached the point where I need to implement a server back-end in order to support the core functionality.The app is built in a way to store certain questions locally (Within the app) and pose the questions to the app user. I need to tweak it such that it retrieves the question from a remote server. Furthermore, the question will reside in a specific folder within the remote DB. So the app will have to fetch the questions from the appropriate folder based on user login.
I have zero server experience and am need of some advise as to where I should begin with this. I would like to know if there is a template spec for this kind of task. With a template spec, I can hire a programmer and talk intelligently. Please help!
Here is a number of solutions:
1) You can use other services that provide backend functionality with REST API (as #Niklas Hein mentioned), it calls BAAS - backend as a service, such as Parse (but Parse is closing his service in one year), BaasBox, etc.
2) You can use CloudKit. This is service created by Apple, where you can store app data in the cloud, with authorization, requests, admin panel, etc.
3) Create you own back end. Here is a large number of languages and web frameworks, so php is not the only one solution. Ruby on Rails, Python Django, NodeJS, and many others on your choice.
There are plenty of BAAS (Backend as a service) provider, like Parse or Firebase. You might want to have a look into them. (Although Parse is going to shut down.)
Another simple way is to look into PHP Laravel.
Laravel is a great Framework which makes it really easy to set up a backend.

I've been developing a project using php that my students use to take quizes (that moodle can't do itself) Now I would like to integrate moodle and my project such that my project authenticates against moodle users and reports grades into a courses gradebook. I've so far been authenticating using direct database reading but I'm very hesitant to do writes to the moodle database. I'm also aware of LTI; I am open to using it but the human readable documentation and any samples are impossible to find. If you could provide me a sample or documentation thats less theory and more applicable for LTI it would be greatly appreciated.
Thanks in advance.
To do this you need to use the Web Services API. You need to setup a web service first, see Using web services. The entire API documentation is available on your Moodle site via Administration > Plugins > Web services > API Documentation.
You need to use moodle's External Tool, which is created precisely for this kind of uses. External tool uses LTI in the background to send user, course, role etc information to an external application and the external application can even send back scores to moodle if configured as a quiz.
Check out : https://docs.moodle.org/23/en/External_tool
You will also have to make your quiz taking app, an LTI provider.
This open source package is out of the box package to create LTI provider in ruby - https://github.com/instructure/ims-lti
There are similar tools in other languages too, but this one is the most polished one.
I have one .php web site and I want to put it in iPad application "web application".
I mean create UIWebView and load files in WebView, so my First question is, is it possible to create this webApp and can I run it on Xcode simulator?
What do I need for implementing this application (Apache, MySQL) inside ipad outside?
Basically I want to have all my .php class inside of app and run it via iPad app, it means that if I hadn't any internet I can run the application.
Since I want to run it in both iPad and XCode simulator.
Would you please give me some hints for implement this application?
A few points you need to think about:
App Store Approval - if you intend to market this app (i.e it's not for jailbroken devices via Cydia, or an in-house corporate app) then you will most likely run in to issues with the approval process.*
You're intending to bundle in a scripting language with your application. Now this may not be an issue depending on whether or not this is exposed to the end-user; but you do run the risk of Apple finding out and pulling the plug.
The alternative to bundling in a scripting language (PHP in your case) is going to be loading the code off of an external server. This is a no-no straight away, as Apple requires your application to have functionality offline - or atleast they did. Where this leaves all the Social Networking and other network-dependant apps... Well, I guess there are exceptions!
Device Performance - you're essentially intending to run a small web server on a mobile device; a tablet in this case. This could be very resource intensive, so is probably not wise. I personally wouldn't want my battery being drained because someone has decided that they want to bundle in a web server with their application.
Your implementation idea itself is sound, in the respect of using a UIWebView. You should probably check out the Apache Cordova/PhoneGap framework, and that should satisfy your needs and provide an off-the-shelf way of packaging up your web app. If you do need custom functionality then it's worth looking at anyway; plugins are relatively easy to develop, there's a wide range available already and the plans for cordova now are to allow developers to implement it into native applications. (Say, if only one view requires PhoneGap functionality etc)
Personally, I fail to see what requires PHP that can not be done via HTML5 and PhoneGap. There are storage options available, SQL options, you're using web technologies so can easily query external web services. It's also a lot safer with regards to app approval - as it's tried and tested; there are many applications build using such solutions already in the store.
I think you need a serious re-think. Otherwise, perhaps you could post some more details?
Please note that PHP is a server-side language. So do you want to run a server on your iPad? If so, you can develop PHP applications on a proper desktop/laptop and then view them on iPad Safari browser over Wifi.
Otherwise you can install LightHTTPd server with PHP libraries, MySQL, CURL and all from Cydia app store on a jailbroken iOS device to get a full environment. For Android there is this app PAW server available which can run an Apache server in such devices.
If you just want to check your website is working fine on small devices, or you want to check responsiveness of your website. Go to:Ipad Peek and run your website on given devices/simulators using url.

I've never used to before, but it might do what you need.
A friend and I would like to create a website to manipulate Facebook data.
The structure is:
a PHP web role (contains the web page, user OAuth login, interacts with queues, and interacts with SQL Azure database)
an F# worker role (does statistics and quite heavy data extractions)
The process is (assuming a new user):
user arrives on the web page and logs onto Facebook via OAuth, the PHP web role then posts a message in a worktodo queue with the login info and token.
F# worker role reads the message off the worktodo queue and starts doing data crunching (using the Facebook API) and stats, then it writes the results to a SQL Azure database. Finally it posts a message to the workdone queue stating it has succeeded in doing the data processing for the user.
Finally the PHP web role reads the workdone queue and notices the work is done, and displays the algorithm results.
I have two questions:
Is there a big flaw in this design?
What is the best way to collaborate: one person will write the PHP and another the F#, is there a way to use development storage from two different machines?
Thanks a lot! (Apologies if some find this stuff too basic, I am very much a beginner in all these matters).
If you wanted to follow a bit more experimental path, you could also try looking at Phalanger. This is a project that compiles PHP code to .NET, so it may be possible to run it directly on Azure and nicely collaborate with F# (Phalanger has a few language extensions that allow you to call any .NET objects and some API for calling Phalanger objects from C#).
I was involved in the project some time ago, but it is now beign developed by other people (and as you can see from the check-ins, it is quite active again and they would surely be interested in collaborating to resolve possible Azure issues). If you were interested, let me know - I can give you some contacts, so that you can discuss the Phalanger status on Azure with them.
I don't see anything wrong with this plan.
I don't think there's a way to have two machines pointing at the same development storage, but you can just use cloud storage (even when running locally). I do that all of the time; you will pay for bandwidth and storage transactions, but for most apps in testing, this cost is trivial.
