What are some best practices for comparing arrays and objects in PHP to ensure accurate results?

When comparing arrays and objects in PHP, it is essential to use the appropriate comparison operators to ensure accurate results. For comparing arrays, you can use the `==` or `===` operators to check if the arrays have the same key/value pairs in the same order. For objects, you can use the `==` or `===` operators to compare if two objects are instances of the same class and have the same properties with the same values. 

// Comparing arrays using the === operator to ensure accurate results
$array1 = [1, 2, 3];
$array2 = [1, 2, 3];

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

// Comparing objects using the == operator to ensure accurate results
class Sample {
    public $value;
}

$obj1 = new Sample();
$obj1->value = 10;

$obj2 = new Sample();
$obj2->value = 10;

if ($obj1 == $obj2) {
    echo 'Objects are equal';
} else {
    echo 'Objects are not equal';
}
