Surprised that $test{2} still works, isn't that outdated?

I thought you had to start counting from 1, not 0.

Wait, why is $test(3) even an option? That's just wrong.

You can use $test[2] and $test{2} for the 3rd character.

I’m pretty sure B and D are the right answers, but I’m a bit confused about the curly braces.

I think I practiced something similar, but I’m not sure if using curly braces is still valid in newer PHP versions.

I remember that string indexing starts at 0, so the 3rd character should be at index 2.

Hmm, the curly brace syntax $test{3} is throwing me off. I don't think I've seen that before, so I'll skip that one and focus on the more familiar array/parentheses options.

I've got a good feeling about the $test[2] option. That's how I usually access individual characters in a string, so I'll go with that.

Wait, is it zero-indexed or one-indexed? I'm a bit confused on that. Maybe I should try both the (2) and [2] options just to be sure.

Okay, let me see... I think the array syntax $test[2] should work, since array indices start at 0. I'll try that one.

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.

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

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