What are the best practices for utilizing array_map function with class methods in PHP?

When using the array_map function with class methods in PHP, it's important to pass the class instance as the second parameter to array_map. This ensures that the class method is called within the context of the class instance. Additionally, make sure to specify the method as an array containing the class instance and the method name. 

class MyClass {
    public function myMethod($value) {
        return $value * 2;
    }
}

$myClass = new MyClass();
$array = [1, 2, 3, 4, 5];
$result = array_map([$myClass, 'myMethod'], $array);

print_r($result);
