The ReflectionParameter class
(PHP 5, PHP 7)
Introduction
The ReflectionParameter class retrieves information about function's or method's parameters.
To introspect function parameters, first create an instance of the ReflectionFunction or ReflectionMethod classes and then use their ReflectionFunctionAbstract::getParameters() method to retrieve an array of parameters.
