  4. None


Correct Option: B

AI Explanation

To answer this question, we need to understand the differences between the echo() and print() functions in PHP.

Option A) echo() - This option is incorrect because the echo() function does not return a value. It simply outputs the provided string or variable to the screen.

Option B) print() - This option is correct because the print() function returns a value of 1 if the output is successful. It also outputs the provided string or variable to the screen.

Option C) Both - This option is incorrect because although both echo() and print() can be used to output values to the screen, only the print() function returns a value of 1 when the output is successful.

Option D) None - This option is incorrect because the print() function returns a value of 1 when the output is successful.

Therefore, the correct answer is B) print().

AI Explanation

To answer this question, you need to understand the different ways to output or display data in programming.

Let's go through each option to understand why it is correct or incorrect:

Option A) echo() - This option is incorrect because the echo() function does not assign the output to a variable. It simply outputs the data to the screen.

Option B) print() - This option is incorrect because the print() function also does not assign the output to a variable. It only prints the data to the screen.

Option C) printf() - This option is incorrect because printf() is a function in C programming language, not in PHP. It is used to format and print data to the screen, but it does not assign the output to a variable in PHP.

Option D) sprintf() - This option is correct because the sprintf() function in PHP can assign the formatted output to a string variable. It allows you to format data and store it in a string variable for further use.

The correct answer is Option D) sprintf(). This option is correct because it assigns the output to a string variable.

Note: It is important to mention that the correct answer may vary depending on the programming language you are using. In this case, the correct answer is for PHP.
