Codeigniter tutorial in Hindi (Libraries) | part 10 ? 2020

"Codeigniter 3 tutorial step by step in Hindi" is a video series for beginners who want to learn the Codeigniter framework from scratch.

This video series is perfect for the beginners who want to learn from scratch, during the video series I will cover most of the topics of Codeigniter framework.

Topic:-
Codeigniter has two types of facilities that can help in the development of the application these are Libraries and Helpers. All the CodeIgniter libraries and helpers are placed in the system folder.

1) Libraries
Libraries are a collection of reusable classes that can assist in the development of the application. In the Codeigniter framework, there are so many libraries that can be used, as per the application requirement. Here are the steps to use a library:-
Step 1) Load Library in the Codeigniter controller or you can load via autoload.php file.
Syntax to load a library:-
$this→load→library('LibraryName');

Step 2) Now you can use a library and its method using sub object for example:-
$this→LibraryName→method_name();

So, it is really simple to load and use libraries in Codeigniter.

2) Helpers
Codeigniter helpers are a collection of methods. It doesn't work the way libraries works, a helper is a file where you will see a series of methods defined. Helpers are mostly used in views but you can also use anywhere in the application you want it.

Here are the steps to use a Helper:-
Step 1) Load helper in the Codeigniter controller or you can load in autoload file. Here is the syntax to load a helper in a controller:-
$this→load→library('HelperName');
Step 2) After loading helper you just directly call its methods.
method_name();

Difference between Helper and Library:-
Libraries are coded in the form of classes(Object-oriented way) and you can use it using an object, while helpers are simple files with methods.

You can directly call the methods of the helper in the application, and you don't need to create an object because they won't work in an object-oriented way.
