How does PHP's approach to object-oriented programming differ from languages like Java and C++ in terms of type sensitivity and OOP principles?

PHP's approach to object-oriented programming differs from languages like Java and C++ in terms of type sensitivity and OOP principles. PHP is a loosely typed language, meaning that variables do not need to be explicitly declared with a specific data type. This can lead to potential issues with type mismatches and errors. In contrast, Java and C++ are strongly typed languages, where variables must be declared with a specific data type and type mismatches are caught at compile time. To address type sensitivity issues in PHP, developers can use type hinting in method signatures to enforce the type of parameters passed to a method. 

class MyClass {
    public function myMethod(string $param) {
        // method implementation
    }
}

$obj = new MyClass();
$obj->myMethod("Hello"); // This will work
$obj->myMethod(123); // This will throw a TypeError
