Solution (By Examveda Team)
This question asks about how to access the first element of an array in PHP. Arrays are like lists of data, and each element has a position, called an index.In PHP, the first element of an array always has an index of 0 (not 1). This is important to remember!
Now let's look at the options:
Option A: $a[1] - This would access the second element, not the first.
Option B: $a[0] - This is the correct way to access the first element of an array.
Option C: $a.1 - This is incorrect syntax for accessing array elements in PHP.
Option D: $a.0 - This is also incorrect syntax.
Therefore, the correct answer is Option B: $a[0]
