How can local variables impact the scope of object variables in PHP?

Local variables can impact the scope of object variables in PHP by potentially overriding or shadowing object variables within a method or function. To avoid conflicts between local variables and object variables, it's best practice to use the `$this` keyword to explicitly reference object variables within methods. 

class MyClass {
    public $variable = "Object variable";

    public function myMethod() {
        $variable = "Local variable";
        echo $this->variable; // Outputs: Object variable
    }
}

$obj = new MyClass();
$obj->myMethod();
