Why Laravel Is The Top PHP Framework In 2020-2021

Numerous PHP-frameworks are accessible to use as open-source and free. Be that as it may, at whatever point we talk about Laravel, then the issue is unique. Try not to stress. It is likewise open-source and free PHP structure; however, it came in presence as the top and a propelled contender to the CodeIgniter system.

It is furnished with numerous highlights; for example, worked in help for client authentication and authorization. CodeIgniter missed these highlights. That is the reason the web advancement process utilizing CodeIgniter was very hard.

The expansion of the above highlights expanded the ubiquity and distinction of the Laravel structure. Numerous Laravel development companies engineers as their significant component for creating web applications and believe it is the best and most prestigious PHP structure.

Engineers likewise use Bootstrap Laravel formats while they grow large and complex applications. Numerous different highlights make Laravel the best PHP system in 2020.

We take an itemized conversation on the highlights and rule of the Laravel PHP system in web advancement:

Application structure

About the application structure in Laravel, it accompanies a default application structure. Its application structure is straightforward to use, thus giving high convenience to begin little or huge applications. With this component, designers can modify the application according to the proprietor requests.

Multiple File Storage System

Laravel is in build with various storage systems like cloud, Amazon, and other Exchanging between these profoundly included, and in vogue distributed storage systems will be a not too bad and simple errand because the API utilized for every one of these systems is the equivalent.

A standout amongst other things like this will be the designer will be permitted to use all these three distributed storage systems just in a single application. It will allow engineers to rapidly and effectively serve these files from various areas with no issue.

MVC Architecture Support

Concentrate on straightforwardness is an indispensable factor between business rationale and introduction being developed. Laravel supports MVC. MVC is named as Model View Controller. This design has a full scope of inherent capacities. MVC empowers engineers to support the presentation and offers reasonable documentation advantage.

To get a full favorable position of the Laravel structure, it is recommended to interface with experts having long stretches of understanding and aptitude as they are the individuals offering the total capacity to your web improvement given by Laravel.

Article Oriented Libraries

Laravel accompanies the enormous assortment of Object-Oriented Libraries fused with numerous pre-introduced and worked in libraries like Authentication library. CodeIgniter, Symphony, and other well-known PHP frameworks don’t offer these sorts of Object-Oriented Libraries.

Laravel Authentication Library is outfitted with a wide scope of cutting edge highlights. A portion of different highlights incorporates checking dynamic clients, cross-site insurance and REquest Forgery encryption, Bcrypt hashing, and secret key reset.

Restriction

Laravel offers restriction benefits that are useful to the engineers in a way to recover strings of a few dialects. Along these lines, the web application will bolster different dialects without any problem. It is beyond the realm of imagination with various frameworks, so it makes Laravel a worldwide marvel.

Pagination

Pagination is a run of the mill task in web advancement; however, Laravel makes it simpler at the initial step. It causes designers to make clever connections for any site created on the HTML and current page. Moreover, the connections made by designers utilizing pagination in Laravel will perfect with Bootstrap CSS structure.

Sharp edge Template Engine

One of the intriguing realities about Laravel is that it gives an in-manufactured layout motor named Blade. The powerful and smooth Blade templating motor necessarily accompanied Laravel 5.1. Laravel accompanies a first anyway still strong templating engine which isn’t accessible in other PHP frameworks.

It helps engineers from using the understandable code in the views. Also, the cutting edge views then effortlessly take care of into simple PHP code and are before revamped they are stored.

In a couple of conditions, altering or erasing an announcement appears to be an extreme errand while dealing with unpredictable and enormous undertakings. Be that as it may, Blade in Laravel encourages designers to expel or change the announcement with no issue handily.

Steering System

Laravel encourages designers to use a directing framework that is exceptionally helpful and straightforward. They require building up an index for the URI and afterward create and execute appropriate connects to the named courses.

The primary advantage is that while making the code, it puts the URIs depended on connections to the particular links and paths and updates them if the course change.

Authentication

There are just a couple of frameworks that realize that making authentication is straightforward and quick. Like this, everything has been designed and included as of now for the web engineers for the most part.

The arrangement files comprise every single extraordinary archive that is basic for dealing with the elements of authentication services.

Programming Task Management and arrangement

In each web advancement, the process task the executives and setup is a fundamental factor that ought to be considered by each engineer top to bottom. It is likewise a necessary errand to be done on schedule. It may be sending some other errands or an email, clearing the database, overseeing undertakings efficiently consistently assume a significant job.

Try not to stress the platitude possibly commonplace, yet usage isn’t as Laravel is here with an order scheduler.

While utilizing the order scheduler, just the code passage will be included your server. Corn calls this scheduler over and over.

After the execution of the order, Laravel assesses the booked errand and run all the pending assignments. As such, Laravel offers ease in planning and dealing with the undertakings.

Security

It is challenging to state if any web application is secure and ensured. With the Laravel PHP structure can give the top security to web applications as the passwords will never get spared inside the system as the understandable content. This is the principle reason Laravel uses the hashed secret phrase for security.

Laravel likewise gives the best counteraction to your web applications from infusion assaults. It utilizes SQL articulations to decrease the opportunity for genuine dangers.

Laravel offers numerous security features that include ensuring courses, encryption, HTTP essential authentication, and so forth.

Programmed Package Discovery

Programmed Package Discovery in Laravel discovers which bundles are wanted by clients to introduce. There is no compelling reason to set up any examination.

It is anything but challenging to impair this element, and engineers can do it with no issue. This component is likewise the purpose behind the ubiquity of Laravel.

In How many ways we can use Model in CakePHP

CakePHP is an MVC based framework and facilitates unlimited flexibility. A model in cake PHP is used for the data source and all the logics that require to gather the data.

Later we use a Model functions to get these formatted data in Controllers and send them to view using the set function.

Here we are going to learn in how many ways we can use a Model or data source in CakePHP applications.

The naming convention followed in CakePHP help us to reduce our effort and to make the development process rapid.

Since Model is used as a logical unit and data source we can use it in any Controller where we need the data, irrespective the name of model and controllers.

A Controller with name “Users” can access the functions written in Model User without any manual initialization. But the question is how to use another Model and its functions in Users Controller?

When we are developing a complex application we usually need to access data from many tables or we can say from many Models in a single controller.

If there is no association then we need to initialize the other Models manually. Once we initialize these models we can use any functions in these models in the Controller. We can use any data source in any controller.

Even we can use the Model in our plugins Model, in the same way, we use in our standard models.

There are different ways to initialize a model in any Controller:

  • Initialize at the start of Controller and use it in any action of Controller.
  • Initialize in the particular action of Controller.
  • Initialize and Using in Another model.

Initialize at the start of Controller and use it in any action of Controller

There are many such situations when we need to use any model continuously in all the functions, then we need to initialize a model that can be used from anywhere.

Here we once initialize the model is available anywhere in a controller to use. We should not use this method when we are using the Model in only a few functions.

This may create overhead to the application when each time a data source is being loaded without reason.

Initialize in a particular action of Controller

When we have limited usage in a controller then it is not a good practice to initialize a model at the start.

We should initialize when we need only.

There may be some particular function that needs to access data from another model.

Initialize and Using in Another model

There are many such situations arrived when you need to use another model functions in your model, then you need to import that model in your model.

When we need additional data apart from association we need to fetch data from a model that is not the current model. CakePHP provides flexibility to use a number of existing model functions in your model.

This facilitates code reusability and improves the maintainability of application and at the same time reduce overhead and development time.

Hope this article will help you in using a model in Cake PHP in different ways.

Happy Learning 🙂

How to start with Codeigniter

What is Codeigniter?

Codeigniter is a PHP based Web development framework.Code igniter follows MVC and HMVC pattern for application development. This is one of the easiest and the simplest MVC frame work available in PHP. It doesn’t demand any configurational setting before execution. We just need to download the Codeigniter source code and to execute it on webserver.

How to and from where we will find the CodeIgniter?

We can download the latest release source code from official website of CodeIgniter [https://codeigniter.com/download]. It is a 2.7 MB zip file for CodeIgniter 3.1.10.

We can also clone it or fork it from Git Hub [https://github.com/bcit-ci/CodeIgniter].

When we will extract we will find 3 folders

  1. application
  2. system
  3. user_guide

application – is what we will use for creating modules,display and our logic will remain there in Models,Views and Controllers.

system – folder is core files of CodeIgniter, that we don’t need to work on.

user_guide – is the tutorial, documentation and examples of how to use Code igniter and this is the best documentation available for any MVC framework.

How to configure it?

No any configuration required. Just put the extracted folder inside your localhost directory and run it, You will find a welcome home screen.

MVC Web Development Framework

What is Web Development Framework?

There is a huge number of server-side scripting languages, using them we can create web applications. Almost the scripts are full-fledged programming language and featured with Object Oriented Programming Systems. Popular of them are Java, PHP, Python, Ruby,Perl. At the early age of web the applications were built on conventional logic and components, are not organized or not reusable. As the next generation, web development technologies came into existence the requirement of frameworks increased.A need for such a tool was very important as they are time and cost efficient.

Now we have many frameworks with huge communities. Frameworks are the collection of basic building blocks and reusable code in an organized manner where maintenance and development both are painless processes. They implement code re-usability, inheritance, security, abstraction, accessibility, integrity, reliability, readability, maintainability in our applications. Now we are able to develop very robust applications in very less time. frameworks are enriched with various libraries and plugin. They also provide flexibility to extend the functionality of the core. Almost the framework is based on Model-View-Controller or MVC development pattern.

What is MVC?

MVC is a software architectural pattern, which provides a modular structure to an application and application is layered into Models(M), Views(V) and Controllers(C).

MODEL

Model is a layer where all the data building logic is present. This layer is abstract from direct access. We write or database queries and fetch and format data in this layer with given parameters. This layer is a central layer of all three.

VIEW

A view is a presentation layer. We see the desired results here in our browser. The user directly communicates with forms and perform actions and submit inputs. This is an end user layer where HTTP response displayed and request triggered by user actions.

CONTROLLER

A controller is an intermediate layer and create a pool between Model the data logic layer and View the representational layer. It collects user actions based on URI and parameters. Routing and reverse routing happen here.

Advantages of MVC Frameworks:

  1. Fast and quick development of complex web-applications.
  2. Collection of Plugins are available for most of the general purpose activities.
  3. Easy maintenance and debugging. Frameworks provide debugger kit , that eases the debugging process.
  4. MVC provides a modular structure to application that is why MVC based applications are flexible and robust.
  5. Most of them provide Database manipulation library, so no need to write custom and complex queries very often.
  6. Inbuilt security and migration features.
  7. Most of them come with a command-line interface to generate code-snippets and modules.
  8. They create SEO friendly URLs to easy for search engines to recognize your application urls.

What are the popular MVC framework based on PHP?

There are numerous MVC framework based on PHP. Some of them are as:
Laravel – Laravel is the most popular PHP framework with the latest release of PHP and suitable for heavy applications.It comes with Inbuilt Authentication and security features. Laravel has a powerful ORM and query builder. Laravel has a unique feature of artisan CLI tool.Blade template engine is used for presentation on view.

Zend Framework

Created by the developers of PHP.Zend Framework is a collection of professional PHP packages with more than 345 million installations. It can be used to develop web applications and services using PHP 5.6+, and provides 100% object-oriented code using a broad spectrum of language features. Zend Framework uses Composer as a package dependency manager; PHP Unit to test all packages; and Travis CI as a Continuous Integration service. Zend Framework also follows PHP-FIG standards and includes an implementation of PHR-7 for HTTP message interfaces (as shepherded by Matthew Weier O’Phinney, Zend Framework project lead).

CakePHP

CakePHP is a Rapid development framework written in PHP 5.6 and having a unique feature of Naming Convention. CakePHP has a powerful tool of bake console. We can create scaffolding within no time. It is suitable for Web services as well as small and heavy applications. We can use a template engine as well for the presentation layer.

Codeigniter

This is a zero-configuration framework and mostly used for small scale application. It comes with all the features of OOPS and security parameters. It is fast ,and the most flexible among others in a group. Code-igniter has wonderful and organized documentation and a huge community over the web. Codeigniter also provide the feature of HMVC and templating.

Yii

Fastest growing over the internet and popular in recent years. Featured with MVC structure and can be used for small as well as heavy applications. It handles complex WSDL services easily.

Phalcon

  • You can also clone the git repository of CodeIgniter.

Directory Structure for Codeigniter 4.x



A newly installed application has six directories:

  1. application
  2. system
  3. public
  4. writable
  5. tests
  6. Docs

Application Structure

  1. The framework still has app and system folders, with the same interpretation as before
  2. The framework now provides for a public folder, intended as the document root for your app
  3. There is also a writable folder, to hold cache data, logs, and session data
  4. The application folder looks very similar to that for CI3, with some name changes, and some subfolders moved to the writable folder
  5. There is no longer a nested application/core folder

The application directory i.e. app is the source code of your application. All the stuff done by you will remain here. The default structure of the app directory is as :

/app

        /Config         Stores the configuration files

        /Controllers    Controllers determine the program flow

        /Database       Stores the database migrations and seeds files

        /Filters        Stores filter classes that can run before and after a controller

        /Helpers        Helpers store collections of standalone functions

        /Language       Multiple language support reads the language strings from here

        /Libraries      Useful classes that don’t fit in another category

        /Models         Models the database and business logic.

        /ThirdParty     ThirdParty libraries that can be used in application

        /Views          Views make up the HTML that is displayed to the client.

The above concepts will help you when you will doing any application on code igniter or you will be in CodeIgniter interview.

Hooks in CodeIgniter

In code igniter hooks are the points before and after the execution where we can call some specific functions.

These functions are called hooks and points where we call hooks are called hook points.

Hooks in Codeigniter are useful when we have to make some changes throughout the application, then we can do this without hacking all the files, just adding one hook at the appropriate point.

We can modify the way of usual rendering in code igniter application.

So hooks facilitate modification in functionality without changing the core.

Hooks in Codeigniter is important part of any Codeigniter Interview.

How we can use a hook in the Codeigniter framework?

Before we use any hook in application we need to enable the hook in config.php file. Set the enable_hook config variable: TRUE,

$config['enable_hooks'] = TRUE;

The Codeigniter framework provides the number of Hook Points to ease the development and modification in the application:

[1]pre_system:
The pre_system is called very early during system execution.

Only the benchmark and hooks class have been loaded at this point.

[2]pre_controller:
As per the name just called before any of your controllers being called.

When all the base classes are loaded, routing and security checks are done a pre_controller hook is called.

[3]post_controller_constructor:
The hook is called just after the controller class instantiated but none of the methods is called.

[4]post_controller:
Called immediately after your controller is fully executed.

[5]display_override:
We have the _display() function in our core and we use it to render our view on the browser after the execution of all programs.

display_override allows use to display our own content at desired places.

$this->CI => get_instance();
$this->CI->output->get_output();

[6]cache_override:
We can call our own function instead of _display_cache() function using the cache_override hook. We can define our own cache display mechanism.

[7]post_system:
At the end of the system execution when final rendering is done post_system is called.

Define a hook :
A hook is defined in the hooks.php file located at application/config

Example of define a pre_controller hook:

$hook['pre_controller'] = array(  
            'class' => 'Classname',  
            'function' => 'functionname',  
            'filename' => 'filename.php',  
            'filepath' => 'hooks',  
            'params' => array('element1', 'element2', 'element3')  
            );  

The Hooks in Codeigniter will boost your learning  Codeigniter.
