Option B is the way to go. Accessing array elements using square brackets is the most straightforward and intuitive approach.

I'm not sure about option D) echo $test{2}. I think curly braces {} are used for variables, not string characters.

Haha, this is a classic PHP gotcha! I remember wasting an embarrassing amount of time on this exact question during my last interview.

I agree with Kristeen. Using square brackets [] is the correct way to access characters in a string.

D looks like the most logical choice to me. Who uses those weird parentheses anyway? Team curly braces all the way!

I always use curly braces for accessing characters in a string. E) echo $test{3}; is the way to go.

I was sure that A and C were the right answers. Guess I need to brush up on my PHP string manipulation skills.

B and D are the correct options. Arrays in PHP are zero-indexed, so the 3rd character is at index 2.
