Go to from your favorite web browser and check that your Symfony website works. You can install them by running the following command:Įcho fs.inotify.max_user_watches=524288 | sudo tee -a /etc/nf You will also probably need Composer, a commonly used dependency manager for PHP. To be able to run PHP code you obviously need to install PHP. Let's start! Prerequisites Install PHP and Composer I will take an empty Symfony application as an example for this article. The commands will be detailed for Ubuntu 18.04, but they can be adapted for Mac OS and possibly for Windows. In this article, I will explain how I managed to make my development environment comparable to PhpStorm's. Moreover, I didn't want to invest €199 in the famous PHPStorm IDE… □ TL DR VS Code extensions you should install and configure for PHP development: I wanted to keep my VS Code habits and proficiency I had from my previous projects in Node.js and Vue.js, so I tried to configure VS Code for PHP development as well. If you have any questions regarding the article, please mention them in the comment section.I recently started programming in PHP using the well-known Symfony framework. If you are new to Python, I recommend that you take DataCamp's free Introduction to Python course. You have now seen how you can implement encapsulation in Python and the difference between the setter, getter and, property. # creating an object for the 'AnotherWay' class Let's check whether it's working properly or not. Make the setter and getter methods as private to hide them. Pass all the getter and setter methods to the property and assign it to the variable which you have to use as a class attribute. # condition to check whether var is suitable or not Obj = will set the value of a by checking the conditions we have mentioned in the method. # creating an object for the class 'Property' Let's test the class Property to check whether the decorators is working properly or not. To set the value of the private variable, we use in front of the method. We have to put a line in front of the method where we return the private variable. Self._a = is used to get the value of a private attribute without using any getter methods. # the attribute name and the method name must be same which is used to set the value for the a(self, var): Let's see how to implement the above class using the decorator. # creating an object for the class 'SampleClass1' Let's check the class by creating an object. # condition to check whether 'a' is suitable or not # calling the set_a() method to set the value 'a' by checking certain conditions Let's implement this by changing the set_a() method in the SampleClass. Let's say if the value we passed is even and positive then we can set it to the attribute, otherwise set the value to 2. Now, what if you want to have some conditions to set the value of an attribute in the SampleClass. If you want private attributes and methods you can implement the class using setters, getters methods otherwise you will implement using the normal way. It doesn't implement any encapsulation feature. It implements the encapsulation feature of OOPS. SampleClass hides the private attributes and methods.What's the difference between the above two classes. # Creating an object for the 'PythonicWay' class You can access it directly using the name of the attributes. You don't need any getters, setters methods to access or change the attributes. Let's write the same implementation in a Pythonic way. This is how you implement private attributes, getters, and setters in Python. # setting a new value to the 'a' using set_a() method # getting the value of 'a' using get_a() method That's why you implemented the getter method. You are not able to access the private variables directly in Python. set_a:- It is used to set the value of a using an object of a class.get_a:- It is used to get the values of private attribute a. _init_:- It is used to initialize the attributes or properties of a class. # setter method to change the value 'a' using an object # getter method to get the properties using an object Let's see how you can implement a private attribute in Python. If you are not familiar with the private attributes or private methods in Python, read this DataCamp article. Setters: These are the methods used in OOPS feature which helps to set the value to private attributes in a class.Getters: These are the methods used in Object-Oriented Programming (OOPS) which helps to access the private attributes from a class.
