Can we declare two functions with the same name in PHP Why or why not?

Short answer: No. There can only be one function with a given name.

Can there be two functions with same name?

That is, you can use the same name for two or more functions in the same program. … An overloaded function must have a parameter list that’s different from all other functions with the same name so the compiler has some way to tell the functions apart.

How many functions can have the same name?

two functions
You are allowed to define two functions with the same name if they have different Types, or if they can be distinguished by their external parameter argument labels.

Is function overloading possible in PHP?

You cannot overload PHP functions. Function signatures are based only on their names and do not include argument lists, so you cannot have two functions with the same name. Class method overloading is different in PHP than in many other languages. PHP uses the same word but it describes a different pattern.

Can we make two functions with the same name but with different number of operators in C?

Function overloading is a feature of a programming language that allows one to have many functions with same name but with different signatures. This feature is present in most of the Object Oriented Languages such as C++ and Java. … Have a void * type of pointer as an argument to the function.

Can two function declare variable with the same name?

Can two functions declare variables(non static) with the same name? Explanation: We can declare variables with the same name in two functions because their scope lies within the function.

Why function overloading is needed in PHP?

Function overloading in PHP is used to dynamically create properties and methods. These dynamic entities are processed by magic methods which can be used in a class for various action types. Function overloading contains same function name and that function preforms different task according to number of arguments.

Why multiple inheritance is not possible in PHP?

As you can see from the code, on calling the method greet() using object ClassC , it’s impossible for the compiler to decide whether it has to call ClassA’s greet() or ClassB’s greet() method. So, this is to avoid such complications, PHP does not support multiple inheritance.

How can stop function overriding in PHP?

The final keyword prevents child classes from overriding a method or constant by prefixing the definition with final . If the class itself is being defined final then it cannot be extended. Note: Properties cannot be declared final: only classes, methods, and constants (as of PHP 8.1. 0) may be declared as final.

How many arguments can pass when the function is overloaded in PHP?

But Other programming languages says , doTask(var1)anddoTask(var1,$var2) are overloaded methods. To call the latter, two parameters must be passed, whereas the former requires only one parameter. so this behavior i.e decision to call a function at coding time is known as static polymorphic i.e method overloading.

What is difference between overriding and overloading?

What is Overloading and Overriding? When two or more methods in the same class have the same name but different parameters, it’s called Overloading. When the method signature (name and parameters) are the same in the superclass and the child class, it’s called Overriding.

What is the difference between function overloading and function overriding PHP?

Function overloading and overriding is the OOPs feature in PHP. In function overloading, more than one function can have same method signature but different number of arguments. But in case of function overriding, more than one functions will have same method signature and number of arguments.

Can PHP class have multiple constructors?

PHP lacks support for declaring multiple constructors of different numbers of parameters for a class unlike languages such as Java. So, if we declare an another constructor in the above example like so. PHP will throw a fatal error upon running the above code.

Can we overload constructor in PHP?

16 Answers. You can’t overload ANY method in PHP. If you want to be able to instantiate a PHP object while passing several different combinations of parameters, use the factory pattern with a private constructor.

Does PHP support multiple inheritance?

PHP doesn’t support multiple inheritance but by using Interfaces in PHP or using Traits in PHP instead of classes, we can implement it. … Classes, case classes, objects, and traits can all extend no more than one class but can extend multiple traits at the same time.

What is the namespace in PHP?

Namespaces are qualifiers that solve two different problems: They allow for better organization by grouping classes that work together to perform a task. They allow the same name to be used for more than one class.

Can constructor be private in PHP?

The constructor may be made private or protected to prevent it from being called externally. If so, only a static method will be able to instantiate the class. Because they are in the same class definition they have access to private methods, even if not of the same object instance.

What is constructor and destructor in PHP?

Constructor is involved automatically when the object is created. Destructor is involved automatically when the object is destroyed. Used to initialize the instance of a class. Used to de-initialize objects already existing to free up memory for new accommodation. Used to initialize data members of class.
