PHP: Get method's arguments?

phpclassobjectmethodsarguments

提问by Rakward

In php I can check all available methods for an object like so:

在 php 中,我可以检查对象的所有可用方法,如下所示:

$methods = get_class_methods($object);

But how can I see wich arguments have to be sent to these methods?

但是我怎么能看到必须向这些方法发送哪些参数呢?

Is there a function for this?

有这个功能吗?

You can use reflection...

您可以使用反射...

$r = new ReflectionMethod($className, $methodName);
$params = $r->getParameters();
foreach ($params as $param) {
    //$param is an instance of ReflectionParameter
    echo $param->getName();
    echo $param->isOptional();
}
