What is operator overloading in PHP?
We have operator overloading, function overloading etc. … When different operations are performed using the same operator, then it is called operator overloading. Similarly, if we define functions having an identical name but different set of arguments, then it is called function overloading.
What is method overloading and method overriding in PHP?
Method overloading occurs when two or more methods with same method name but different number of parameters in single class. PHP does not support method overloading. Method overriding means two methods with same method name and same number of parameters in two different classes means parent class and child class.
What is operator overloading with example?
This means C++ has the ability to provide the operators with a special meaning for a data type, this ability is known as operator overloading. For example, we can overload an operator ‘+’ in a class like String so that we can concatenate two strings by just using +.
What is method overloading and method overriding with example?
Overloading vs Overriding: Difference between Method Overloading and Method Overriding
| Method Overloading | Method Overriding |
|---|---|
| Is an example of compile-time polymorphism | It is an example of runtime polymorphism |
| Return type can be different but you must change the parameters as well. | Return type must be same in overriding |
Which method gets declared in the parent class when we need to implement the class that contains a particular method to be determined by the child class?
Overriding is done so that a child class can give its own implementation to a method which is already provided by the parent class. In this case the method in parent class is called overridden method and the method in child class is called overriding method.

What is method overloading What are the different rules to follow while overloading methods provide a suitable example to illustrate method overloading?
If a class has multiple methods having same name but different in parameters, it is known as Method Overloading. If we have to perform only one operation, having same name of the methods increases the readability of the program.
Can we create a program without main method?
Yes You can compile and execute without main method By using static block.
