I want to create a mobile app for an exisiting website that runs on PHP and MYSQL. Phonegap users, please kindly inform me if it's possible to send mobile notification by interacting with my web application?
Here's an example for better understanding: A web application where users create a list of to do's. User entries are stored in a web database. The objective is to send notifications to their phones via the website server when a "to do" event is due. Can this be achieved with Phonegap?
Yes. Yes it can. Have you tried much yet?
Notifications while inside the application are a snap - just a regular getJSON poll to some kind of endpoint will work. If you want to use native notifications, that's harder.

I am new to swift and was wondering how could I send commands from a server to my iOS application ? For example imagine a website where I can click a button and that button would then trigger a pop up to all users of my app. Is this possible and if so can someone lead me in the right direction?
Much appreciated
Yes, you can
Silent Push Notification: Send a Silent Push Notification and handle in your app. But you need user permissions to receive Notifications. Add "content-available" : 1 to your notification content.
Using Sockets: There are many options to create connection b/w device and server. example: https://socket.io/
It depends what you are trying to do, you might want to look at apple push notifications and see how they work. From there I would suggest looking into sending notifications to the apple server (that would send the push notifications to the app). I hope this sends you in the right path good luck!
I just assume that you have an application that a number of users are using and you have a web application that can show all mobile users.
For the most of cases, whenever a user is using the application, you let the application send a request with your user's information to your server and your server records the user information in the database.
When your website wants to show all the users' information, it just fetches all the information from the database instead of sending sort of commands to all applications to get information in real-time.
Of course, there is a more complex way to send commands to all running applications to get the results. However, it requires both server-side and client-side (ios application) implement functions sending commands in real-time using Socket or MQTT etc. This is more complex and it requires iOS application running in front or background at the same time.
I assume that using HTTP to record every mobile user is more suitable for your case.
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 tried searching these issues. Some sites say I need to do some stuff with php in order to make 3rd party server while others don't mention anything. some says it need JSON. Guide me please. PS I am a beginner and know java, XML,SQL only.
You should only need one server. The second server you are reading about may be the Google GCM cloud server? When I did a GCM project a few years ago, I had one server, it happened to be a App Engine instance. It generated events and sent them to Google via the GCM api and then onto onto the device. I don't remember it being that difficult.
I did have more than one server in the mix though, there were others that sent messages to the AppEngine server, but it was not required to send a GCM message.
Google Cloud Messaging (GCM) is a service that enables developers to send data from servers to both Android applications or Chrome apps and extensions.
So if you want to send data to the users of your App then you must have an interface or dashboard from where you can send some data (typically push notification) to the users of your app.
This dashboard (server from which you can send data) can be developed by using PHP or any script languages.
Now a though can come up in your mind:
"I am suppose to develop both the mobile app and the server then what
role does GCM play?"
Yes, GCM is playing a vital role indeed. The server we have to develop is just to design an interface so that you can type your message/notification and select the recipients. Rest of the part of (managing the queue, communication with the apps checking for authentication and all other stuffs will be done by mighty GCM )
In order to have an bird-eye overview you can take a look on this image collected form android hive
Server side coding is doesn't need you to be expert in php. So you can go through to this article. It helped me a lot to learn.
I am currently building a SNS for both web and iphone/android applications.
When an user writes on the wall or leaves a message, the server needs to push notifications to all related users. Users who are logged in on PC will receive it via Socket.io and those who are logged in on iPhone or android apps will get it via GCM/APN.
What is the best way to send push notification(GET) to all these users from a php web server?
cURL seems to do the right work but is extremely slow on my server.
The web server will need to send notifications to at least 3 different servers at once at unnoticeable speed.
Any suggestions?
I'm in the process of building such an application and I have to be honest and advise you to use Zend Framework. There is also a lot of database planning to be done as read/writes to and from a database will be high. Specifically use Zend_Mobile or visit my blog for the gcm solution http://www.rogerethomas.com
Ideally you should run a cluster of servers processing messages and queues. Push messaging can get out of hand quickly and taking the time to plan it properly will pay off I promise you.
I need to make chat application for android. I thought of using PHP script to implement the chat application. Basic idea is to send message form android client to PHP script and making use of PHP script send the messages to the MySQL database. These messages will be broadcasting to other people. But the problem is auto broadcasting messages to other people. Is there a way to do this using android and php?
You can do the following
Make a persistent tcp connection between your device and the PHP server
When a message is broadcast send it over the tcp connection of each device
On the device process this notification and you are good to go.
If you want to use Java on the server side I have your project already finished and ready to ship ;) (just kidding)
But if you are interested check out the Device-To-Device messaging framework of OpenMobster Mobile Cloud platform. The project is free and open source. Here is a link to the Device-To-Device Framework: http://code.google.com/p/openmobster/wiki/D2DPushFramework
and http://code.google.com/p/openmobster/wiki/PushFramework
The above three steps are already taken care of by the framework. The developer just has to focus on the App itself
Good Luck!!!!
Yes there is several ways to do this
you can just post to the server and from the server send push notifications to the mobiles
You can make the mobile keep checking for updates if it exists
You will require to finish these steps ( at least ):
setup a PHP web server
register for Android Push Notification (you probably need that)
create database schema
write your own codes to allow users to submit & retrieve chat messages
security !!!
You'd probably want to use Google's C2DM, though it's not free.
Your php server would get a message from a phone, do it's processing, then make a HTTPS request to Google's C2DM service, which sends the messages to the destination android device.
http://code.google.com/android/c2dm/#push-process
Don't use C2DM, its a deprecated. Please go through the GCM(Global Cloud Messaging),
please follow this link,

Have you heard of Firebase? Firebase. Making a chat app with Firebase is like eating pizza.
