I'd say the result is 'a good time', but that's probably not the right answer for a certification exam.

E) Parse error. The + operator is not valid for merging arrays in PHP, so this code will result in a syntax error.

Make sure to use the correct syntax for merging arrays in PHP.

I'm going with D) false. The array_merge function returns a new array, so $a[2] will not be defined, resulting in a false value.

I agree with B) 3. The value at index 2 in the merged array is 3.

I think it's E) Parse error because the syntax of array_merge is incorrect.

The correct answer is C) 2. The + operator will merge the arrays, but it will preserve the keys from the second array, so the element at index 2 will be 2.

No, it's actually C) 2. The keys from the second array are preserved.

I think the answer is B) 3. The array_merge function will combine the two arrays, and the element at index 2 will be 3 from the first array.
