Given the following case:
<?php
class ParentClass {
public $attrA;
public $attrB;
public $attrC;
public function methodA() {}
public function methodB() {}
public function methodC() {}
}
class ChildClass extends ParentClass {
public $attrB;
public function methodA() {}
}
How can I get a list of methods (and preferably class vars) that are overridden in ChildClass?
Thanks, Joe
EDIT: Fixed bad extends. Any methods, not just public ones.
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.
getMethods() then foreach through them calling getDeclaringClass()->getName(). If name != class name, then it's been overriden. The same can be done with getProperties()
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
)
)
See the manual for more useful information on reflection: https://www.php.net/manual/en/class.reflectionclass.php
class ChildClass extends ParentClass
