How is "->" used in object-oriented programming in PHP?

In object-oriented programming in PHP, the "->" symbol is used to access methods and properties of an object. This is known as the object operator. By using "->", you can call methods or access properties of an object within a class. Example:

class Car {
    public $color;

    public function setColor($newColor) {
        $this->color = $newColor;
    }

    public function getColor() {
        return $this->color;
    }
}

$myCar = new Car();
$myCar->setColor("blue");
echo $myCar->getColor(); // Output: blue
