    Can you assign the default values to a function parameters?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Yes, you can assign default values to function parameters. This allows the function to be called with fewer arguments, as the default values will be used for any parameters that are not provided. This is useful when you want to provide a default behavior for a function but also allow the caller to override it if desired.

    Can you create a class in pHP?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Yes, you can create a class in PHP. In object-oriented programming, a class is a blueprint for creating objects (instances of the class) that have properties (variables) and methods (functions). PHP supports object-oriented programming, allowing developers to define and create their own classes. By creating a class, you can encapsulate data and functions into a single entity, making your code more organized and modular.

    Which of the following keyword terminates the for loop or switch statement and transfers execution to the statement immediately following the for loop or switch?

    • Break

    • Continue

    Correct Answer
    A. Break
    Explanation
    The keyword "break" terminates the for loop or switch statement and transfers execution to the statement immediately following the loop or switch. When encountered, it breaks out of the loop or switch and continues with the next line of code outside the loop or switch. This allows for more control and flexibility in program flow, as it can be used to exit a loop prematurely or skip certain iterations. On the other hand, the "continue" keyword is used to skip the current iteration of a loop and move on to the next iteration without executing any further code within the loop.

    Which of the following magic constant of pHP returns function name?

    • _LINE_

    • _FILE_

    • _FUNCTION_

    • _CLASS_

    Correct Answer
    A. _FUNCTION_
    Explanation
    The magic constant _FUNCTION_ in PHP returns the name of the current function. It is useful for debugging and logging purposes, allowing developers to easily identify the specific function that is being executed at any given time.

    Which of the following provides content type of the uploaded file in pHP?

    • $_FILES['file']['tmp_name']

    • $_FILES['file']['name']

    • $_FILES['file']['size']

    • $_FILES['file']['type']

    Correct Answer
    A. $_FILES['file']['type']
    Explanation
    The correct answer is $_FILES['file']['type']. This is because the 'type' key in the $_FILES array provides the content type of the uploaded file in PHP. The content type represents the MIME type of the file, which indicates the nature and format of the file data.

    Which of the following is true about php variables?

    • Variables can, but do not need, to be declared before assignment

    • Variables in PHP do not have intrinsic types - a variable does not know in advance whether it will be used to store a number or a string of characters.

    • Variables used before they are assigned have default values.

    • All of the above.

    Correct Answer
    A. All of the above.
    Explanation
    All of the statements mentioned in the options are true about PHP variables. In PHP, variables can be assigned without prior declaration, they do not have intrinsic types, and if a variable is used before assignment, it will have default values. Therefore, the correct answer is "All of the above."

    Which of the following function returns selected parts of an array?

    • Array_reverse()

    • Array_search()

    • Array_slice()

    Correct Answer
    A. Array_slice()
    Explanation
    The function array_slice() returns selected parts of an array. It allows you to extract a portion of an array based on the specified start and length parameters. By using this function, you can retrieve a specific range of elements from an array without modifying the original array.

    • Header()

    • Reflect()

    Correct Answer

    Explanation

It allows the server to send a response back to the client with a new location, causing the client to redirect to that location. This function is commonly used in web development to redirect users to a different page or URL.
