PHP get overridden methods from child class

Question

Given the following case:

Answer 1

Reflection is correct, but you would have to do it like this:

$child  = new ReflectionClass('ChildClass');

// find all public and protected methods in ParentClass
$parentMethods = $child->getParentClass()->getMethods(
    ReflectionMethod::IS_PUBLIC ^ ReflectionMethod::IS_PROTECTED
);

// find all parent methods that were redeclared in ChildClass
foreach($parentMethods as $parentMethod) {
    $declaringClass = $child->getMethod($parentMethod->getName())
                            ->getDeclaringClass()
                            ->getName();

    if($declaringClass === $child->getName()) {
        echo $parentMethod->getName(); // print the method name
    }
}

Same for Properties, just you would use getProperties() instead.

Answer 2

You can use ReflectionClass to achieve this:

$ref = new ReflectionClass('ChildClass');

print_r($ref->getMethods());
print_r($ref->getProperties());

This will output:

Array
(
    [0] => ReflectionMethod Object
        (
            [name] => methodA
            [class] => ChildClass
        )

)

Array
(
    [0] => ReflectionProperty Object
        (
            [name] => attrB
            [class] => ChildClass
        )

)
