What is an abstract class in PHP?

Hypertext Preprocessor (PHP) is a scripting language that serves as a versatile language used primarily on the website; He talks to databases, creates special effects and logic, and helps with administrative features such as managing members of the website. The PHP class code is used to make capsules that can be used continuously, so the programmer does not have to write the same encoding for each instance. The abstract class in PHP, which has been introduced with PHP5, is similar to the conventional class, but is used, but only part of the class code will be needed, while other sections will have to be defined for specific uses. The abstract class in PHP can be set as public or protected but not private. Within this class, the programmer writes a set of instructions such as CODE to turn the vehicle left or brake. This type of coding emulates object -oriented coding or coding that separates parts of the code on objects that have their own code sets. PHP is not naturally object -oriented code, alE can imitate it through this method.

The

Incomplete parts are filled when an abstract class is called during the program. For example, an abstract vehicle class will have basic instructions that work with all types of vehicles such as cars, trucks and motorcycles. However, each vehicle has its own specific needs and the abstract T will allow the programmer to fill in these specific needs without having to write separate coding for each vehicle. This makes coding more efficient, minimizes errors and facilitates rapid changes in each object that uses an abstract class.

Class

pHP are specified as public, protected or private. Each of these labels acts as a shield that limits code visibility according to the user's access level. Class settings as public allows each user to see the code, protected status limit of some of the code and private allows only specified users to see the code. The abstract class in PHP can be set as public or protected but cannot be private.
