What best practices should be followed when comparing arrays in PHP to ensure accurate results and avoid confusion?

When comparing arrays in PHP, it is important to use the `===` operator to ensure accurate results. This is because the `==` operator checks for equality in values, while `===` checks for equality in both values and types. By using `===`, you can avoid confusion and ensure that the comparison is strict. 

$array1 = [1, 2, 3];
$array2 = [1, 2, 3];

if ($array1 === $array2) {
    echo "Arrays are identical";
} else {
    echo "Arrays are not identical";
}
