I'm going to create an Android app for the first time, and I wanted to do it in PHP, I've done some research and found the likes of PhoneGap, but I'm still quite short in the area, could someone give me a start?
What I'm going to be doing is a simple app for testing, a shop where you search for products, add them to your cart and check out, and the names of the products you ordered will be entered to a database.
Basically;
Search for products->add to cart->check out->info sent to database (all through PHP).
Where should I start?
Cordova is mainly a JavaScript framework that exposes native device features as JavaScript functions. Think of a cordova application like a plain HTML & Javascript website running in a Webview within your mobile application. The PHP interpreter isn't available on a mobile device, which is why you cannot package PHP files into a cordova app and expect it to work.
You could however write your backend in PHP and use XMLHTTP calls (in JavaScript) to retrieve data and present it to the user.
Additionally you can use any JavaScript framework in combination with Cordova so if you are familiar with any of them (like jQuery, Knockout or Angular) that would be an advantage. I'd suggest starting with a Cordova tutorial, like for example this one: https://ccoenraets.github.io/cordova-tutorial/index.html
Another project that is getting alot of attention lately is the Ionic project, which is also based on Cordova. I'd think based on your requirements this would be a great framework to use: http://ionicframework.com/

This probably seems stupid question. But I'm new to ionic apps. I wanted to clear this before development.
Can we build ionic app without API? like we normally do for our website.
Example:
If you go to MySite.com, you will see the site running in php with normal rendering. Would Ionic work same way or it has to go through API Send/Receive request for data handling?
Ionic has no direct requirement on data access. It is built on AngularJS, which is in turn built on Javascript. Best practices would generally have you accessing JSON data from a server by using a mechanism that is Angular aware such as $http, $resource, Restangular, etc.
However, you can execute any javascript based browser command (or even load something like jQuery to perform the data access). However, as soon as you go outside of Angular, then you will have to deal with the additional complexity of making sure the digest cycle is run whenever you have updated values that may be reflected on your view because of data binding.
And, just to be clear, none of this has anything to do with what's happening on the server side. When you are asking about accessing "without API", do you mean accessing HTML files vs. JSON data? Ionic is built to be a SPA (single page application) that is installed on the mobile device and doesn't require internet access to run once it's installed.
Therefore, especially if external/live data isn't required (imagine some type of calculator where you enter values and results can be calculated with just the data in the app on the handset -- without the need for a live server at all), Ionic apps don't REQUIRE access to an external server at all.
You could provide traditional hyperlinks to other html files, but at that point it would no longer be running the packaged/installed files that form the basis of the installed app on the handset and would instead be a web app that is relying on an external server for all views. And, of course, even if it does require access to data from a server, the often massive increase in speed by not round tripping the server with a new HTML page (only a relatively tiny JSON payload in most situations) makes it feel much more like a true native app.
In ionic, the rendering happens on your phone. The server simply provides data. So if you need any data from a server (usually yes) then you need an API.
Ionic is focused on building native/hybrid mobile apps rather than
mobile websites.

As per definition, an API only defines the way your ionic app can interact with your php script. In principle, there are no rules on how you design this interaction. So yes, you can keep it quite traditional/old-fashioned. Don't get the concept of an API mixed up with the concepts of RESTful or SOAP APIs etc.
I've got a book I bought online - O'Reilly's Building Android Apps with HTML, CSS and JavaScript. The idea is that you can use these 3 to create a website that can be converted to an Android app by using a Java conversion tool.
Hopefully someone will be familiar with this, and hopefully this is possible - if I have a website that is already created that also includes PHP, could this be used for the app?
I've created PHP sites before, and the one I'm specifically looking at is referencing a MySQL database, hence my need to use PHP for the app. The website is heavily based on PHP.
No you can't (Unless you created your own framework which runs a local php server inside of the device which can be accessed by a webview). Php is a server side language. Html and JavaScript are client side. These html app creation frameworks use the webview to run apps. Be careful as there are performance issues when running through webview as it is not a native app (projects like crosswalk help but still many issues). Popular frameworks include ionic (Angularjs), titanium (is mostly native but from my experience limiting), and appgyver (Angularjs).
Yes you can! If by "converting" the website to app you mean displaying the website in a chromeless view mode (without address bar).
If you wan't to use phonegap / cordova you can still use the existing PHP code as backend for the database (Maybe rewrite it into a Restful API).
If you want your app to run natively and without internet connection, then you are out of luck though.
Hi I have recently began to build mobile open cart sites for mobile browsers. I would like to take it a step further and build native apps using phonegap. My question is , does phonegap support a structure like opencart? Are php files supported?
Would it be possible for me to build a fully functioning opencart site and integrate it successfully with phonegap?
There is very little information online regarding this question.
A Phonegap app cannot contain any server side scripting like PHP. It can only contains HTML, css and Javascript.
But you can always do request to a remote server that runs PHP.
Opencart has quite a few ajax interfaces in various parts of the app. These call controllers that deliver sections of a page usually. I have not looked into the full remote API to know if you can build a full shop app that uses the opencart backend.
If you look down that ajax calls path you may find enough functionality to produce the phonegap app.
Closed. This question needs to be more focused. It is not currently accepting answers.

I have had a PHP application developed. I want to use phonegap.com or a similar approach to develop native applications based on the same MySQL database. In other words, connect the mobile applications with the web one.
It needs to do one or two things differently. Firstly, use the native GPS features to determine where a user is - I'm guessing this can just be done via HTML5?
Secondly, send push notifications whenever the web-application user receives a notification.
All of the information is already there, on the MySQL database, and everything apart from the two features above function properly.
I'm am currently having an API developed for everything on the web-application - making it API-centric. In my head, it will be easy to connect the two versions via the API.
For example, a user signs up on the web application. He is then offered to iphone app for download.
Is it possible to get him to log-in with the same via the iPhone. On the other side, is it possible for him to search the database, via the iphone, and "add a new friend" - making the connection of the two users in the friends table - in that, the friend is also a friend on the web-application?
I've been reading a lot on all of the available options and am still very confused! Any help would be very helpful.
I'm not a phone developer myself, however I've just finished building a native Android App which connects to a website and is able to login, do stuff that is possible to do on the website as well. If the GPS tracking integration is using the native features than it is unlikely to use HTML5 (though I'm not sure how it works).
Basically in order to connect to a remote database/server you need to make HTTP requests from the phone to you server side script.
So just to conclude:
In order to achieve the result you're looking for the work-flow could look like this:
1.Mobile user fills a form ->
2.App does an HTTP request to a server side script ->
3.script does the hard work (e.g. connects to the database) ->
4.script renders a result ->
5.Mobile app displays the result.
I hope this helps.
Im my objective opinion there are three possibilities:
Get started with Objective-C
You will have to learn how to code and you will get the best native experience for your users. This will easily allow you to use the GPS positioning or you can cache content on your phone. A key problem with the internet connection on the phone is that the internet connection can be flaky. So you have to design for this. You took the right approach already: using the direct MySQL C-API to connect directly to the database server would not work that well, because this protocol is not stateless. You have to first login to the server and then you can send your SQL queries.
By using your API which is hopefully stateless, maybe even a RESTful API, then you can take some nice shortcuts for your native iPhone app. You could then use the RestKit library to easily convert your JSON answers from the server into objects, do caching and other nice features.
Write a web app
The second possibility would be to build a nice web app using state-of-the-art HTML5 technologies. The great thing about that is that you then would write an Android app as well as both mobile devices use a webkit browser. Well it is not exactly the case as there are different versions of Android out there with different screen sizes, but in general this assumption holds. Take a look at Google's web app for Google Calendar for example, I think it is a good compromise. You can also get a home screen icon for this and you will have no app approval process and can update anytime. Using HTML5 offline storage gives you some degree of freedom.
Using Phonegap
The option of writing the app in PhoneGap or some other HTML wrapper framework which will generate Objective-C code is a possible one, but in my opinion this is not really a good option. The reason is that you are working on some kind of intermediate layer and if anything goes wrong or you encounter bugs you will have to dive down to objective-c anyways. The other problem is concerning updates of iOS. It can break some dependencies and then you have to wait until your intermediate gets updated to use the new features.
Phonegap would be a good idea to develop this app. Phonegap although supports client side script only - which means you cannot embed php in its code. However you can easily create AJAX calls in your script that get and send data from your already developed php app/api.
Phonegap also supports GPS and data storage options where you can store the data locally and sync later when internet is available.
For reverse sync (server to client), you would have two options.
1. Create a javascript to make frequent ajax calls to check for updates.
2. Use Push Notifications (Here a tutorial for iOS APNs and Phonegap integration) - http://devgirl.org/2012/10/19/tutorial-apple-push-notifications-with-phonegap-part-1/
Using phonegap depends on one's preference. On the positive side, you save on time/cost as same code is used for all platforms. On the negative side, it has a slight lag when changing pages causing it to look like a website, but you can avoid that by using something like jquery mobile to prefetch all pages and then animate them back and forth. This will also help in uploading data in a separate independent thread while the user would be free to roam around the app.
Hope that helps.
Simply put, the best way to go is for you to use a php web service with phone gap.
You can also go through android using PHP and android. This is a very good and simple way to go. Try the tutorial here
You may tray Xamarin (part of .Net) with the free version of Visual Studio Community and then interact with your PHP web-app. You can then compile the native Xamarin app (written in C#) to Android and iOS.
I want to develop a module for card scanning using CSSN.They gave the sample code for another languages like C#,Delphi etc.(except PHP).
Is there any sample code for scanning the document using PHP with this CSSN device?Whether we can develop application for this scanner using PHP?
Looking at their website, and based on the fact that they're using ActiveX controls, I get the feeling you'll never get this working on a language that doesn't use Microsoft's runtime. Even if you were able to somehow get it working, I doubt you would get much support from them on it.
I would recommend, instead, writing a program in a language they support that can in turn talk to your PHP application. As the SDK sends events to your intermediate app it can send them on to your PHP program, and the PHP program can send commands to the SDK through the intermediate app.
