I'm totally new about mobile application development and i'm getting really confused about few things.
I'm actually developing web application under zend framework 2 (php framework) and Zend studio (IDE).
So to not starting all over again i want to make a mobile app (for learning purpose) with ZF2 and Zend studio.
I've been following that tutorial.
So i'm not sure to understand how the data are stored. Until now i have used MySQL with phpmyadmin for my web applications.
From what i understand, i need to use a cloud server such as Parse, phpcloud or else, am i right?
My question is, how the website and the mobile app will share the same data?
typically you will have to write web services that will expose a few methods which in turn will get the required data you want to share.
So your connectivity should look like Mobile APP --> Web Service --> DB
Make sure to thrown in some kind of authentication to avoid abuse of your web services. The webservice can be deployed on the same server that is hosting the website
One more way is to access the mysql database directly from your mobile application . This is NOT recommended because essentially you are exposing your DB to the world. This is OK in case of a corporate application which will only work within your company network or with a controlled environment.
You can use a PaaS like Heroku or Openshift to host your web application. But The web application must also expose a set of web services, which can be used to send and receive information to and from the mobile app.
I think the tutorial you mentioned explaining about building a mobile web site. That is you need to support your web site for small screens like mobile phones or tablets.
If you are planing to build a native mobile application, best approach would be to expose core services using RESTful web services.
using the same database... you have 2 options.... either make a php script to attend the mobile request, or creating a special mysql user that has access to the same database your website uses...

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.
Currently building a hybrid app. using Ionic Framework with PHP for backend services
I am having a case where a user has got his profile in Web app and Mobile App as well.
If the user adds two stories as favourites (Its kind of a reading app) from his mobile app or Web app,how do I sync that?
Here are the scenarios:
1) User marks the stories favourites from web app and when I come online through mobile app, display it.
2) User marks the stories favourites from mobile app when he is offline(Now this will be stored in LocalDB). So again when he comes online sync with the server?
I know there are services like Firebase which provides syncing service.
But What If I would want to develop a Custom Syncing service on my own for my application? Is that an extremely complicated process?
If yes and it can be developed ,then how should I proceed ? A basic idea? What are the best practices that I should consider?
Any links would be appreciated?
I know some of the comments recommended CouchDB in combination with PouchDB. That is a much better solution than trying to implement your own synchronization service with MySQL.
However, since you're using Ionic Framework you can also use Couchbase. Take the following example application:
https://github.com/couchbaselabs/TodoLite-Ionic
If you chose this solution you would have three moving parts. You would be replacing MySQL with Couchbase Server and running the Couchbase Sync Gateway to orchestrate any data between the device and the server. You can still keep your PHP backend if you have a web version of your application as there is a PHP SDK for Couchbase.
Two write-ups on this can be found here:
http://blog.couchbase.com/using-couchbase-in-your-ionic-framework-application-part-1
http://blog.couchbase.com/using-couchbase-in-your-ionic-framework-application-part-2
In the long term, you're going to find NoSQL much more pleasant to work with when it comes to APIs and mobile than MySQL.
Can be useful to write a POST method on the backend that receives the data from your local from the app and some user data (session, access tokens and other thing you considered neceasary). On the body for the request you include the data needed to be synced. The backend takes the body. Parse it and rreturn a result (http code) Based on that you can decide if the app should delete the local data or only mark it as synced on the local database
I am developing an iOS application that will be communicating with a PHP/MySQL web service to send/receive data. My plan is to also have a website that has similar functionality to the iOS application and will also interact with the web service. Should I be using a framework to build this web service (I am thinking about Laravel)? Is it a good idea to have the web service separate from the website?
Thanks.
If you are building a native application and requires connection to your website or collecting info, I suggest you to build you own API to access the data from ios using json.
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.
A simple google search pulled up this free framework: http://www.ipfaces.org/
I've never used to before, but it might do what you need.
Is it possible to use the Google App Engine with datastore only and keep your application on an external traditional server?
I'm interested in the GAE for Business SQL service coming soon but I only want to use GAE for the database. I would like to keep the php application on a traditional server for a variety of reasons.
Is this possible?
Yes it is possible and GAE is fairly used in this specific scenario; think about the hundreds of Iphone/Android applications that use GAE as back-end.
A simple common design would have:
A Web API to communicate with GAE datastore since you can't connect directly to it from your php application. Have a look to restlet for a cool RESTful Java web framework that supports GAE or the new Appengine-rest-server Python project .
A security check to validate that the requests are coming from the php application (HMAC / SSL).
