In PHP 5.x, how can I detect if a class is abstract or not at run time?

Question

I'm looping through an array of class names in PHP, fetched via get_declared_classes().

How can I check each class name to detect whether or not that particular class is an abstract class or not?

Use reflection. ReflectionClass->isAbstract()

Use it like this:

$class = new ReflectionClass('NameOfTheClass'); $abstract = $class->isAbstract();
