How does the use of ArrayObject in PHP differ from regular arrays when accessing elements at specific indexes?

When accessing elements at specific indexes, ArrayObject in PHP differs from regular arrays because it requires using the `offsetGet()` method instead of the square bracket notation. This method allows for more flexibility and control over how elements are accessed within the ArrayObject.

$myArray = new ArrayObject(['a', 'b', 'c']);

// Accessing element at index 1 using offsetGet() method
echo $myArray->offsetGet(1); // Output: b
