If $a represents an array with numeric indices in PHP, the first element accessed by . . . . . . . .

Solution (By Examveda Team)

This question is about how we access elements in an array in PHP. Arrays are like containers that hold multiple values.

In PHP, arrays are indexed, meaning each value has a specific number associated with it, called an index. These indices start from 0 (not 1).

So, to access the first element in an array named $a, you use the index 0. This means you'd write: $a[0]

Let's look at the options:
* Option A: $a[1] This would access the second element of the array (because indices start from 0).
* Option B: $a[0] This is the correct way to access the first element of the array.
* Option C: $a.1 and Option D: $a.0 These are incorrect ways to access array elements in PHP. You use square brackets ([]) to access elements by index.

Therefore, the answer is Option B: $a[0]
