How to make a mobile application from a ready-made CRM using HTML+JS+PHP?

Question

JavaScript

Greetings! self-written crm. Read about jquerymobile and phonegap. What is better to use in my case to create an application for android, and what about PHP, because there are all calls to Mysql, somehow replaced with js?

Answer 1

what to do with PHP because there are all calls to Mysql

Make a REST API through which the mobile application will communicate.
Read about jquerymobile and phonegap.
It is better to do on native for the PL platform.

Answer 2

It is necessary to boil the self-written API to the self-written crm.
Then, using this API, write a native application for android.

Answer 3

and what about PHP, because there are all calls to Mysql, somehow replaced with js?

Of course, you don’t need to replace it, leave the server with PHP and MySQL on the Internet, and let the application be the client part, like a web interface in a browser.
Phonegap just allows the easiest and fastest way to separate the web interface (HTML & CSS & JS) and "bring" it into the application, the easiest way, apart from the option to insert the "engine" (WebKit) into the application, that is, just open the site in application.
