PHP: Get method's arguments?
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();
}
