Do you have experience using reflection mechanisms in development?

In PHP, the reflection mechanism allows for dynamically inspecting classes, methods, properties, and other code elements at runtime. This is useful, for example, for creating universal libraries, autoloaders, ORM, or frameworks.

An example of using ReflectionClass to get a list of class methods:

class Test {
    public function foo() {}
    private function bar() {}
}

$reflection = new ReflectionClass('Test');
$methods = $reflection->getMethods();
foreach ($methods as $method) {
    echo $method->getName() . "\n";
}

This approach helps to write more flexible and extensible code, but requires caution due to possible overhead and complexity of maintenance.
