What is Class?
A PHP class is a group of values with a set of operations to manipulate this values. Classes facilitate modularity and information hiding. Classes are used to define a new data type.
What is Object?
Object is a compound data type, Values of more than one types can be stored together in a single variable. Object is an instance of user defined class.
Rules :
- A variable starts with the $ sign, followed by the name of the variable.
- A variable name must start with a letter or the underscore character.
- A variable name cannot start with a number.
- It can’t be PHP reserved word.
- You can’t assign computed value inside a class. ($a = 12+5; )
- You can’t concatenate in the class.(public $name=”ravi”.”Kumar”;)
