Question 1

________Any representation of data in which the implementation details are hidden
A)overloading
B)data Abstraction
C)Encapsulation
D)member function

Accepted Answer

Data abstraction is a programming concept that allows you to hide the implementation details of a data type from the user. This can be done by creating a class or struct that contains the data and the methods that operate on the data. The user can then interact with the data type through the methods, without having to know how the data is actually stored or processed.

Question 2

__________ refers to a concept where we encapsulate all the data and member functions together to form an object.
A)overloading
B)data Abstraction
C)Encapsulation
D)member function

Accepted Answer

Encapsulation is the concept of bundling the data (attributes) and methods (functions) that operate on the data into a single unit called an object, ensuring that the object's internal state is hidden from the outside. This is a fundamental principle of object-oriented programming.

Question 3

__________ These are the function defined inside a class and are used to access object data.
A)child class
B)class
C)member function
D)parent Class

Accepted Answer

Member functions are defined inside a class and are used to access object data. They operate on the objects of the class, manipulating and retrieving the data of those objects.

Question 4

________ This is a programmer-defined data type, which includes local functions as well as local data.
A)child class
B)class
C)member function
D)parent Class

Accepted Answer

A class is a programmer-defined data type that encapsulates local functions (methods) and local data (attributes) to create objects.

Question 5

_______ A class that inherits from another class. This is also called a subclass or derived class.
A)child class
B)class
C)member function
D)parent Class

Accepted Answer

A child class is the correct term for a class that inherits from another class, making it a subclass or derived class.

Question 6

_________ An array with a numeric index. Values are stored and accessed in linear fashion.
A)associative array
B)multidimensional array
C)Numeric array
D)None of these

Accepted Answer

Numeric arrays are defined by having numeric indexes, which allows for the storage and linear access of values.

Question 7

____________An array with strings as index. This stores element values in association with key values rather than in a strict linear index order.
A)associative array
B)multidimensional array
C)Numeric array
D)None of these

Accepted Answer

An associative array uses strings as indexes rather than numbers, allowing for element values to be associated with key values, not just a linear index.

Question 8

__________ An array containing one or more arrays and values are accessed using multiple indices
A)associative array
B)multidimensional array
C)Numeric array
D)None of these

Accepted Answer

A multidimensional array is an array that contains one or more arrays, allowing values to be accessed using multiple indices.

Question 9

Validation means check the input submitted by the user.
A)true
B)false
C)both a and b
D)none of these

Accepted Answer

Validation indeed involves checking the input submitted by the user to ensure it meets the required criteria or format before processing or storing it.

Question 10

There are two types of validation are available in PHP. They are as follows ?
A)Client-Side Validation
B)Server Side Validation ?
C)input type validation
D)only a and b not c

Accepted Answer

Client-Side Validation and Server-Side Validation are the two types of validation available in PHP. Input type validation is not categorized as a separate type of validation in PHP.

Question 11

_________ Validation is performed on the client machine web browsers.
A)Client-Side Validation
B)Server Side Validation ?
C)input type validation
D)output type validation

Accepted Answer

Client-Side Validation is performed directly in the user's web browser, allowing for immediate feedback without the need to communicate with the server for each validation step. This enhances user experience by providing quick responses to input errors.

Question 12

___________ After submitted by data, The data has sent to a server and perform validation checks in server machine.
A)Client-Side Validation
B)Server Side Validation ?
C)input type validation
D)output type validation

Accepted Answer

Server Side Validation is the process where data is sent to the server, and validation checks are performed on the server machine.

Question 13

Core PHP means solving a Mathematical problem by using paper and pen and Frame work means solving Mathematical problem by using a calculator.
A)true
B)false
C)both a and b
D)none of these

Accepted Answer

Core PHP is a programming language, while a framework is a set of tools and libraries that can be used to develop web applications.
