In this video, we will discuss how to learn about the Libraries, Routing and Helper Codeigniter and what is the difference between helper and library Codeigniter.
CodeIgniter is a powerful PHP framework that is used to create dynamic web applications. It has many helper and library functions that are used to streamline the development process.
CodeIgniter has many helper functions that are used to streamline the development process. They can be found in the /system/core folder and they can be accessed by using $this->helper('functionname'). These functions help with tasks such as form validation, URL manipulation, database queries, etc.
CodeIgniter also has a library folder which contains many libraries for different tasks such as MySQL databases, authentication, sessions, etc. These libraries can be accessed by using $this->load->library('libraryname').
To create a route in CodeIgniter, you need to add the following lines of code:
$route['POST'] = 'post';
$route['GET'] = 'get';
The get method in CodeIgniter is used to retrieve data from the database. The syntax for this method is: $this->db->get($id). The post method is a function that is used to send data from the web browser to the web server. It's typically used for sending data in HTML form, but it can also be used for sending any type of data. The post method sends data from the browser to the server in an HTML form. This means that it can be used to send any type of data, not just HTML.
A route is a set of instructions that tell CodeIgniter where to send a user based on what they're doing. The most common use of a codeigniter route is to define the default view that should be displayed when a user visits the site.
A CodeIgniter route is a type of routing that uses the CodeIgniter PHP framework. It is a way of organizing your website's URL structure to make it easier for search engines to crawl and index your site. It also enables you to keep track of the URLs for each page on your site, so you can easily change them without breaking links.
Some benefits of using a codeigniter route are:
- Easier access to customizing routes via .htaccess file
- Easier access to customizing routes via config/routes.php file
- You can change URLs without breaking links
- You can have multiple routes

In CodeIgniter, the main difference between Helper and Library is that Helper is a file with a set of functions in a specific category that is not written in an Object Oriented format, whereas Library is a class with a set of functions that allows creating an instance of that class that is written in an Object Oriented format.
Libraries are an important aspect of the CodeIgniter system. It comes with a large number of libraries that help to speed up the development of applications. The system library can be found in the system/libraries directory. All we have to do now is load the library we wish to work with.
A helper function is a function that does a portion of another function's calculation. Helper functions are used to make your programmes more readable by giving computations descriptive names. They also, like functions in general, allow you to reuse computations.
Each assistance file is only a collection of functions belonging to a specific category. It's just a bunch of procedural functions. Each helper function carries out a single task and is independent of other functions. Because Helper Files are not loaded by default in CodeIgniter, the first step in utilising one is to load it.
There are helpers in CodeIgniter that can assist you with various tasks. Every helper file is a set of functions aimed at completing a specific task.
Helper: Helper is a function that is used to execute the code that is written in a particular file.
Library: Library is a collection of functions and classes. These are grouped together for the convenience of other programmers.
A library can be used by more than one application. A helper, on the other hand, can only be used in one application which includes all its files.
Codeigniter is a powerful, open-source PHP framework that helps web developers to create websites that are not just responsive but also fast.
The Codeigniter library list contains libraries that can be used in the Codeigniter framework, including common libraries like jQuery, AJAX and Bootstrap.
Helper functions are used to create reusable code blocks. They are called by the controller or other helper functions.
Helper functions can be used to create reusable code blocks that are called by the controller or other helper functions. These reusable blocks of code can be used in a variety of ways and help developers save time in writing repetitive code as well as making their application more modular and easier to maintain.
Helper functions provide a way for developers to create reusable pieces of code that can be called by the controller or other helper function. These reusable pieces of code can be used in a number of ways, which helps developers save time when writing repetitive code and makes their application more modular and easier to maintain.
Helper functions are used to provide a set of common functionality for the application. This can be anything from string manipulation to database interaction. Helpers can be used to provide a common set of functionality for all the models in the application, or they can be created on a per-model basis.
Library classes are used to provide reusable code that is intended for use by more than one model. They should not contain any business logic and should only contain functions and properties that could be reused by other models in the application.
A route is a way for Codeigniter to associate a URL with an action.
Codeigniter routes are defined in the routes.php file and can be configured to respond to any URL pattern.
The following are some of the most common route types:
- A GET request can be handled by a route that returns data, such as a list of articles or search results.
- A POST request can be handled by a route that saves data, such as when adding an article to the database.
- A PUT request can be handled by a route that updates data, such as updating an article's title and content.
