PHP 7

About php 7:
                - PHP 7 was released in December 2015.
                - The main reason behind the PHP7 after PHP5.X is, PHP6 had already existed in the past as an experimental project but never reached the production phase and also there had been many resources available about PHP6.
Features of php 7:
                - PHP7 can boost your application development by using the latest resources.
                - It boosts application execution twice but you will also need fewer servers to serve the same       amount of users.
                - It improves Error Handling where you replace fatal and catchable fatal errors with exceptions.
                - It allows you to access class member on cloning of class.
                - It allows you to create Anonymous classes.
                - Anonymous classes are useful for simple one-off objects. With these classes, you can define a class and instantiate an object inline.
                               
                                - Example:
                                                class Category {
                                                }
                                               
                                                $category = new Category {
                                                                public function getCategory() {
                                                                                return "home";
                                                                }

                                                };

As a symfony developer what you should take care when symfony standard edition is legacy:

Now  symfony standard edition is legacy . So no need to worry much just go threw article and understand whats new in symfony 4 if standard edition is legacy now. This is the main difference in Symfony 4 from symfony 2 and symfony 3 . Older symfony versions provide by default doctrine, twig, form, validation, profiler, annotations and many other components. But some time user do not want to use it. Suppose what if user do not want to doctrine or twig? Still he has doctrine and twig in his dependency. That makes symfony heavy framework. When starting a new project developers do not like to assemble things manually. So symfony 2 and 3 provides standard edition for developers to start a big project. But was hard to scale down project and decrease dependency if user do not require some packages. Symfony 2 and 3  are big success and in years developers are now aware with composer and dependency injection. So adding/removing a new package is not a big deal. So symfony chose...

Laravel: How to protect .env files?

.env files: If you develop your applications using Laravel, you probably use .env files every day in your development life. We use these files to store the most secret information of our application. Be it database credentials, the application key or any third-party service credentials. So simply put: We do not want anyone to get access to these files!

To search for public .env files, all you need to do is google for one of these terms: DB_USERNAME filetype:env DB_PASSWORD filetype:env APP_DEBUG filetype:env Secure your .env files The reason that these .env files are accessible and also get scraped is because of two things: Misconfigured shared hosting The .env file has the wrong access rights Shared hosting If you use shared hosting, please make sure that the root folder of your Laravel application is not accessib...
