Are there any specific PHP settings or configurations that could be causing the PHP script to behave unexpectedly after the object operator?

The issue of unexpected behavior after the object operator in PHP scripts could be caused by incorrect object instantiation or method calls. To solve this issue, ensure that the object is properly instantiated and that the method is being called on the correct object.

class MyClass {
    public function myMethod() {
        // method implementation
    }
}

// Correct instantiation and method call
$object = new MyClass();
$object->myMethod();
