Actually, the output is 1 because the increment function is not returning the updated value.

I think the output is 2 because the increment function should increase the value by 1.

Wait, why is the output not 1? Isn't the function just incrementing the value and then returning it? I'm confused.

The output will be 2. The increment operator (++) increments the value of $val by 1, so after calling the increment() function, the value of $val should be 2.
