PHP uses functions to simplify repetitive tasks and allow for greater variation.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
PHP uses functions to simplify repetitive tasks and allow for greater variation. Functions in PHP allow developers to encapsulate a set of instructions that can be reused multiple times throughout the code. This helps in reducing code duplication and makes the code more modular and maintainable. Functions also allow for greater variation as they can be customized with different parameters and return values based on the specific requirements. Therefore, the statement "PHP uses functions to simplify repetitive tasks and allow for greater variation" is true.Rate this question:

Would you use a function for basic tasks?
- A.
Yes
- B.
No
Correct Answer
A. YesExplanation
Using a function for basic tasks is beneficial for several reasons. Firstly, it promotes code reusability as functions can be called multiple times throughout a program. This saves time and effort in writing the same code repeatedly. Additionally, functions enhance code readability and organization by breaking down complex tasks into smaller, manageable chunks. They also allow for easier debugging and maintenance as any changes or fixes can be made within the function itself. Therefore, using a function for basic tasks is a recommended practice in programming.Rate this question:
