What is the significance of the T_OBJECT_OPERATOR error in PHP?

The T_OBJECT_OPERATOR error in PHP occurs when the "->" operator is used incorrectly, typically when trying to access a property or method of an object that doesn't exist. To solve this issue, ensure that the object being referenced is properly instantiated and that the property or method being accessed actually exists within the object. Example PHP code snippet:

class MyClass {
    public $property;

    public function myMethod() {
        return "Hello, World!";
    }
}

$obj = new MyClass();
echo $obj->property; // Accessing existing property
echo $obj->myMethod(); // Calling existing method
