This is an example using ReflectionMethod() to check if the parent class method is abstract or not. Calling an abstract method of a parent class will crash PHP. 

<?php
abstract class modProcessor {
    abstract public function process();
}

class ConcreteClass extends modProcessor {
   
     public function process() {
        $reflectionMethod = new ReflectionMethod('modProcessor', 'process');
        if (! $reflectionMethod->isAbstract()) {
            parent::process();
        } else {
            echo "Cannot call abstract parent method";
        }
    }
}

$c = new ConcreteClass($modx);

$c->process();
