I'm building a unit testing framework for PHP and I was curious if there is a way to get a list of an objects methods which excludes the parent class's methods. So given this:

class Foo
{

    public function doSomethingFooey()
    {
        echo 'HELLO THERE!';
    }
}

class Bar extends Foo
{
    public function goToTheBar()
    {
        // DRINK!
    }
}

I want a function which will, given the parameter new Bar() return:

array( 'goToTheBar' );

WITHOUT needing to instantiate an instance of Foo. (This means get_class_methods will not work).


Use ReflectionClass, for example:

$f = new ReflectionClass('Bar');
$methods = array();
foreach ($f->getMethods() as $m) {
    if ($m->class == 'Bar') {
        $methods[] = $m->name;
    }
}
print_r($methods);

List all methods of a given class, excluding parent class's - php, You can use get_class_methods() without instantiating the class: $class_name - The class name or an object instance. So the following would work: $bar_methods = array_diff(get_class_methods('Bar'), get_class_methods('Foo')); If you want to receive all methods of a given Class in another Class you should use the PHP5 Reflection API. The following source allows to retrieve all methods from a derived class in its (abstract) Base Class.


You can use get_class_methods() without instantiating the class:

$class_name - The class name or an object instance.

So the following would work:

$bar_methods = array_diff(get_class_methods('Bar'), get_class_methods('Foo'));

Assuming there aren't repeated methods in the parent class. Still, Lukman's answer does a better job. =)

Class inheritance, a list of an objects methods which excludes the parent class's methods. So given this: class Foo { public function doSomethingFooey() { echo 'HELLO THERE! Most of the modern programming languages such as Java, C#, C++ follow OOP principles. So the good news is that learning object-oriented programming fundamentals will be valuable to you in a variety of circumstances—whether you’re working in Python or not.


$class_methods = get_class_methods('Bar');

From the PHP Documenation

This will not instantiate the class, and will allow you to get an array of all of the classes methods.

I'm not completely certain that this won't return parent class methods, but get_class_methods will work for uninstantiated classes. If it does, you can use Alix's answer to remove the parent's method from the array. Or Lukman's to use the reverse engineering aspect of PHP internal code base to get the methods.


BTW, if you type in new Bar(), it is going to create a new instance of Foo, as Bar extends Foo. The only way you can not instantiate Foo is by referring to it statically. Therefore, your request:

I want a function which will, given the parameter new Bar() return:

Has no possible solution. If you give new Bar() as an argument, it will instantiate the class.

Class Abstraction - Manual, The syntax to extend another class is: class Child extends Parent . By default, all methods that are not specified in class Rabbit are taken generated for extending classes without own constructors constructor ( args )  The Arrays class in java.util package is a part of the Java Collection Framework. This class provides static methods to dynamically create and access Java arrays. It consists of only static methods and the methods of Object class. The methods of this class can be used by the class name itself. Class Hierarchy: java.lang.Object ↳ java.util.Arrays


For anyone else wondering how to check if specific method belongs to specified class or its parent class, you can do this by getting its class name and then comparing it with actual class name like following.

$reflection = new \ReflectionMethod($classInstance, 'method_name_here');
if($reflection->class == MyClass::class)
echo "Method belongs to MyClass";
else
echo "Method belongs to Parent classes of MyClass";

3. Data model, Our child class may define optional arguments not in the parent's signature Old code that has no user-defined classes or functions named 'abstract' should run without You would have your class implement a particular interface if you were declare all their methods as abstract are not interfaces with different names. The goal of parenting is to teach kids to develop self-discipline. Many parents feel spanking is necessary for effective discipline. When parents learn and apply the three Fs of Effective using the parenting techniques on this page and others, they find that yelling, screaming and spanking disappear and a positive relationship is established.


3. Data model, If there is no __init__() method, the class must be called without arguments. C.x is translated to C.__dict__["x"] (although for new-style classes in particular there are a is depth-first, left-to-right in the order of occurrence in the base class list. A simplified version of MOF code that includes the class name, parent class (if any), and class properties, in alphabetical order, with data types. Methods table. If a class has methods, the methods are listed in the table immediately following the syntax block. Each implemented method is linked to a reference page. Properties list


Getting All Members of a Class Hierarchy, This search of the base classes uses the C3 method resolution order which behaves sequences, or mappings if they have methods with certain special names. from a class without __slots__, the __dict__ and __weakref__ attribute of the  if you are trying to deep-copy an object with get_object_vars(), strange behaviour can accidentally clobber your original object properties. please read very, very carefully: get_object_vars() may either return references to *or* deep copies of the object's properties *depending on whether that property has been set with the -> operator*.


That's why you can't remove parent methods in Python, You need to map all members of a class, including inherited members, into a dictionary of try: # Try getting all relevant classes in method-resolution order mro = list(aClass._ _mro_ _) except AttributeError: # If a class has no _ _mro_ _, then it's a classic class def getmro(aClass, recurse): mro = [aClass] for base in aClass. The getElementsByClassName() method returns a collection of an element's child elements with the specified class name, as a NodeList object. The NodeList object represents a collection of nodes. The nodes can be accessed by index numbers. The index starts at 0.
