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

Answer: Option B

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 $a</strong>,youusetheindex<strong>0</strong>.Thismeansyo{u}^{\prime }dwrite:<strong>$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: $a.1</strong>and<strong>OptionD:$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]
