Questions:
Say I got a class like:
<?
class ObjectModel {
}
and I got some other classes like:
<?
class SomeNewClass extends ObjectModel {
}
class SomeOtherNewClass extends ObjectModel {
}
Is there a way to get the children (SomeNewClass & SomeOtherNewClass) based on the ObjectModel class?
How to&Answers:
class ObjectModel {
}
class SomeNewClass extends ObjectModel {
}
class SomeOtherNewClass extends ObjectModel {
}
class SomeOtherNewClassLol extends ObjectModel {
}
function get_extends_number($base){
$rt=0;
foreach(get_declared_classes() as $class)
if(is_subclass_of($class,$base)) $rt++;
return $rt;
}
echo get_extends_number('ObjectModel'); //output: 3
Yes, you can do it, DEMO
Answer：
You can iterate all classes returned by get_declared_classes() and inspecting their Reflection (Reflection::isSubclassOf)
But – this won’t work when you are using autoloading.
Answer：
Not sure if this is going to get downvoted but you can hack your way through:
get_declared_classesget_parent_classfor each class on 1
It’s not pretty, but if the child classes are loaded, it’s possible.
