Classes in PHP : A class is a unit of programmer-defined data type that describes the characteristics and behaviors of something, or of the group of things. A class includes local functions as well as local data<\/p>\n

For Example A class called Car, would describe the characteristics and behaviors common to all cars.<\/p>\n

A PHP<\/a> Class has 3 main elements<\/p>\n

PHP Data Member<\/h3>\n

Data members are also variable but difference is that they are in encapsulated form.<\/p>\n

PHP Property<\/h3>\n

A property is a variable inside the class which can contain some information. Like Name is the property of student class.<\/p>\n

Methods are functions inside the body of class, methods can also be accessible by those three types of users.<\/p>\n

 <\/p>\n

Syntax<\/strong> : To create a class, use PHP\u2019s class<\/b> keyword.<\/p>\n
