How can developers troubleshoot and debug PHP errors related to member functions in objects?

To troubleshoot and debug PHP errors related to member functions in objects, developers can check if the object is properly instantiated before calling its member functions. They should also ensure that the member function exists within the object's class definition. Using error reporting functions like error_reporting(E_ALL) and ini_set('display_errors', 1) can help identify the specific error messages.

class MyClass {
    public function myFunction() {
        // function implementation
    }
}

$obj = new MyClass();

if ($obj instanceof MyClass) {
    $obj->myFunction();
} else {
    echo "Object is not properly instantiated.";
}
