Does Google Chrome web store support server sided technologies such as PHP or Python?
I am currently making a productive web application which i have already implemented in python but i wish to give it a nice little web application interface and also harness the power of PHP...
Does Chrome support Python or PHP; or does Chrome even support Server sided scripting?
I am learning how to develop chrome apps from here...
If a member is aware of any better tutorials please inform me...
Or is it that i just have to build a normal web applications and add a logo and manifest and zip it and publish it?
Thankyou...
The platform supports server-side technologies the same way a C++ or Java application would support them: through HTTP (probably RESTful) interfaces that the server side of your app (if any) exposes. For example, your app might make a request to http://example.com/api/foo/bar/baz?param1=123¶m2=456, and might get back a JSON response that your app would then parse. It doesn't really matter which server-side technology you're using, because the API looks the same from the app's perspective.
If you're asking about PHP, Ruby, Python, Go, node.js, etc., running on the user's machine as a client-side app, no, that's not how Chrome packaged apps work (though in theory one could get one of those environments running as a NaCl module that then generates client-side code). Instead, you write code in a very similar way to how you'd write a pure AJAX app: in JavaScript, without navigation, with the content/data being fetched in a RESTful fashion from whatever server/service you use (or none in the case of something like a calculator or simple game that doesn't talk to the network at all). Incidentally, we're finding that very AJAXy apps are relatively simple to convert to packaged apps.
Check out all the samples at https://github.com/GoogleChrome/chrome-app-samples to get more an idea of the shape of the platform.

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.
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.
I am a php developer with a few web apps like a project management app and a forum i'd like to move to Android and iPhone.
I've heard of developers using Sencha Touch and PhoneGap to develop native apps and I know they support HTML5, CSS and Javascript, but how abot PHP? And is are there any other APIs/frameworks I should consider that better support local server scripting?
Speaking about webapp, maybe you can avoid building an app by having a mobile enabled version of your website compliant with all the client browsers.
Have a look at jquerymobile, it is compliant with mostly all the mobile browsers and you will be able to reuse your code.
To answer correctly, you can call your webservices using ajax to fetch json/xml/etc data from Phonegap because it is using jQuerymobile ;-)
Have a look at this discussion here on Stackoverflow :
Passing formdata from Phonegap to PHP with JSON
Hope this helps
PHP is a server-side scripting language and your .php files have to be stored on the server side. You can access them asynchronously with Ajax, so no, you can not include php files (with reasonable time and effort) in your app.
The only smart way to go here is native iOS apps, forget PHP, Android and the rest of that crap. By the way I'm not trying to be an iOS snob here but am just reflecting on a few realities. One is that iOS apps can actually make money though a web replacement app might not. The second issue is that going native demands a reboot on your part, that is best done on one platform until you get up to speed. The third issue is that users now a days expect well performing apps that don't have a lot of web cruft in them. Fourth the Android marketplace is screwed, you are far more likely to establish that critical user base on iOS as you can target a handful of platforms running the latest generation of iOS, android is by comparison a pathetic mess of old versions of android running on all sorts of hardware.
On iOS look a BlueAlien as an example of a better than web method of accessing Reddit.
I have accessed .net webservices in iPhone,now i like to develop PHP webservice which has to be consumed by my iPhone application.
Is it possible to consume a PHP web service in iPhone,if possible can anybody suggest me a good tutorial or web reference for designing a simple web service in PHP and consuming it through a iPhone application.
Thank a lot in advance...
Yes, it's perfectly possible. The client (iPhone) doesn't care in the very least what programming language you use on the server, as long as the output (HTML, XML, JSON, whatever else you want to consume) is something the client understands.
You don't need a tutorial, it's no different from making a normal website with PHP.
I want to develop web applications for smartphones using jQTouch. For server side scripting, I prefer PHP and MySQL database server for back end persistence.
Is there any book that helps in learning how to develop a web application for smartphones using PHP, MySQL and jQTouch?
For developing the client side of your mobile web app (or web applications for smartphones) check out "Building iPhone Apps with HTML, CSS, and JavaScript" by Jonathan Stark. He is currently project maintainer.
Another alternative to jQtouch is Sencha Touch. Sencha Touch lets you develop more complex web applications than with jQtouch. This is a new library, so there is no book on Sencha Touch, however you could learn a lot from the examples, where a book is not necessary. In addition they have the forums.
Things to consider here:
David Kaneda is the mind behind both
projects. I guess what he learned from jQtouch he applied it in Sencha.
jQtouch is a plugin for jQuery with
CSS and themes
Sencha Touch is based on ext js an
javascript libary
jQtouch is MIT license and is part of
Sencha Labs
Sencha Touch has a commercial license
and a GNU GPL license v3.
I've been using jQtouch for the path 10 months and found that it has it limits. If your web app has complex functionality, then consider trying out Sencha Touch. In case you just want to make a web site mobile friendly then use jQtouch.
From testing the demos, Sencha can better cross platform support than jQtouch. Especially if you want to target users with iOS devices (iPad, iPhone, iPod Touch).
All this is regarding the client side of your web application. Regarding the server side of your web application, you could take two approaches.
First you could divide your web app
in 2: server side ( a
webservice or API) and the client side build using jQtouch or Sencha. The communication between them can be done using JSON or XML. The advantage is that your server side will be independent of the choice of client side library. So, in the future if you wish to add a new client type or change libary, the server part is not affected. However, this adds more complexity to your implementation i.e. client authentication, session management, security.
Second way of doing it is the "traditional" way, where your servcer side language generates (based on the requests) the HTML of your web application. In this case you just need to use CSS and some javascript to adapt to the different screens. Or just use jQtouch. This could be less of a hassle but you loose some flexibility and scalability.
