How does the "->" symbol relate to object-oriented programming in PHP?

The "->" symbol in PHP is used to access properties and methods of an object in object-oriented programming. This symbol is used to indicate that we are interacting with a specific instance of a class. To access a property or method of an object, we use the object instance followed by the "->" symbol and then the property or method name. Example: ``` class Person { public $name; public function greet() { echo "Hello, my name is " . $this->name; } } $person = new Person(); $person->name = "John"; $person->greet(); ```
