What best practice should be followed when initializing arrays in PHP to avoid potential errors or unexpected behavior?

When initializing arrays in PHP, it is best practice to explicitly define the array as an empty array using the array() construct or the [] shorthand. This helps avoid potential errors or unexpected behavior that can occur when using uninitialized arrays.

// Initializing an empty array using array() construct
$myArray = array();

// Initializing an empty array using [] shorthand
$myArray = [];
