How can instance variables be accessed within a method in PHP?

Instance variables in PHP can be accessed within a method using the `$this` keyword followed by the arrow operator `->`. This allows the method to refer to the specific instance of the class and access its variables. By using `$this->variableName`, you can read or modify the instance variable within the method. 

class MyClass {
    public $instanceVar = "Hello";

    public function printVar() {
        echo $this->instanceVar;
    }
}

$obj = new MyClass();
$obj->printVar(); // Output: Hello
