This may sound like alot of work fodeigniter do. But we aren’t done yet. We are starting to configure it specifically for our new helloworld app. They are just PHP classes that contain functions which work with information from the database. Looking for something to help kick start your next project? This code connects to a MySQL database called ” helloworld ” on a localhost with the username “root”, and the password, “root”.

This is tutorisl function that will be displayed when no other is provided – e.

To display all the records received from the database, we put it in a “foreach” loop which loops through all the elements. A successful implementation of this lets developers modify their user interface or backend with out affecting the other. That way, when you go to the address http: CI also has a view tutoorial that we do not need. The view file is what the user sees and interacts with, it could be a segment of a page, or the whole page.

CodeIgniter Documentation

You need exceptional performance. CodeIgniter is developed by EllisLab and has thorough, easy to understand documentation. You’ll also need to open up the config.

In the controller index function, we need to load the model, query the database, and pass this queried data to the view. Too start off you will need to download CodeIgniter and upload it to your server. Below is a description of MVC. If we visited http: Frameworks allow for structure in developing applications by providing reusable classes and functions which can reduce development time significantly.

This pattern isolates the user interface and backend i. Below is a list of reasons of what makes CodeIgniter a smart framework to use? You may have noticed that we are using php alternative syntax, this provides an convenient and time saving way to write echo statements.

If, for example, we created a function called coreigniter, we could find this as http: There are a few things you can do to improve your CodeIgniter experience – like removing that annoying index. This tutorial will attempt to show you the basics of setting up the framework, including how to build a basic hello world application that uses the MVC approach.

Everything You Need to Get Started With CodeIgniter

After we have loaded the model, we can access it through its model name and the particular function. We’ll do a quick test to see if CI is up and running properly. Essentially, they are simplified functions to create queries.

You can pass an array of variables to the view through the second argument of the load model function. Its goal is to enable you to develop projects much faster than you could if you were writing code from scratch, by providing a rich set of libraries for commonly needed tasks, as well as a simple interface and logical structure to access these libraries.

Everything You Need to Get Started With CodeIgniter

If you’re up and running, we should finish the configuration. It enables developers to build web applications faster, and it offers many helpful code libraries and helpers which speed up tedious tasks in PHP. To pass data to a 2.13 we need to assign it to an array item and pass the array – which recreates the array items as a variable in the view file.

You need broad compatibility with standard hosting accounts that run a variety of PHP versions and configurations.

Some downsides to frameworks are that they provide unwanted classes, adding code bloat which makes the app harder to navigate. You do not want to be forced to learn a templating language although a template parser is optionally available if you desire one. Models are optional in CI, but it’s considered codeigjiter practice to use them.

Another nifty trick is to turn on CI’s ability to parse PHP alternative syntax if its not enabled by the server.
